Updated (2017): See .NET Core Releases to learn about newer releases.
We are excited to announce the release of .NET Core 1.0, ASP.NET Core 1.0 and Entity Framework Core 1.0, available on Windows, OS X and Linux! .NET Core is a cross-platform, open source, and modular .NET platform for creating modern web apps, microservices, libraries and console applications.
This release includes the .NET Core runtime, libraries and tools and the ASP.NET Core libraries. We are also releasing Visual Studio and Visual Studio Code extensions that enable you to create .NET Core projects. You can get started at https://dot.net/core. Read the release notes for detailed release information.
The Visual Studio team also released Visual Studio 2015 Update 3 today. You need that release to build .NET Core apps in Visual Studio.
We are releasing .NET documentation today at docs.microsoft.com, the new documentation service for Microsoft. The documentation you see there is just a start. You can follow our progress at core-docs on GitHub. ASP.NET Core documentation is also available and open source.
Today we are at the Red Hat DevNation conference showing the release and our partnership with Red Hat. Watch the live stream via Channel 9 where Scott Hanselman will demonstrate .NET Core 1.0. .NET Core is now available on Red Hat Enterprise Linux and OpenShift via certified containers. In addition, .NET Core is fully supported by Red Hat and extended via the integrated hybrid support partnership between Microsoft and Red Hat. See the Red Hat Blog for more details.
This is the biggest transformation of .NET since its inception and will define .NET for the next decade. We’ve rebuilt the foundation of .NET to be targeted at the needs of today’s world: highly distributed cloud applications, micro services and containers.
Moving forward .NET Framework and .NET Core and Xamarin are all important products that will continue to evolve, for Windows, cross-platform cloud and cross-platform mobile, respectively. The .NET Framework and traditional ASP.NET will continue to be relevant for your existing workloads. You can share code and reuse your skills across the entire .NET family so you can decide what to use and when, including mobile apps with Xamarin. And because we designed .NET to share a common library (the .NET standard library) .NET Framework, .NET Core and Xamarin apps will share new common capabilities in the future.
Getting Started
It’s really easy to try out .NET Core and ASP.NET Core on Windows, OS X or Linux. You can have an app up and running in a few minutes. You only need the .NET Core SDK to get started.
The best place to start is the .NET Core home page. It will offer you the correct .NET Core SDK for the Operating System (OS) that you are using and the 3-4 steps you need to following to get started. It’s pretty straightforward.
If you want to use Visual Studio, make sure you have Visual Studio 2015 Update 3 installed. You’ll need to install the .NET Core Tools for Visual Studio.
To give you an idea, once you have the SDK installed, you can type these three simple commands for your first “Hello World” app. The first generates a template for you for a console app, the second restores package dependencies and the last builds and runs the app.
dotnet new
dotnet restore
dotnet run
You’ll see (no surprise!):
Hello World!
You’ll likely get bored of “Hello World” quite quickly. You can read more in-depth tutorials at .NET Core Tutorials and ASP.NET Core Tutorials.
Check out the Announcing EF Core 1.0 post to find out how to get started with Entity Framework Core 1.0.
The .NET Core Journey
About two years ago, we started receiving requests from some ASP.NET customers for “.NET on Linux”. Around the same time, we were talking to the Windows Server Team about Windows Nano, their future, much smaller server product. As a result, we started a new .NET project, which we codenamed “Project K”, to target these new platforms. We changed the name, shape and experience of the product a few times along the way, at every turn trying to make it better and applicable to more scenarios and a broader base of developers. It’s great to see this project finally available as .NET Core and ASP.NET Core 1.0.
Open source is another important theme of this project. Over time, we noticed that all of the major web platforms were open source. ASP.NET MVC has been open source for a long time, but the platform underneath it, the .NET Framework, was not. We didn’t have an answer for web developers who cared deeply about open source, and MVC being open wasn’t enough. With today’s releases, ASP.NET Core is now an open source web platform, top to bottom. Even the documentation is open source. ASP.NET Core is a great candidate for anyone who has open source as a requirement for their web stack.
We’d like to express our gratitude for everyone that has tried .NET Core and ASP.NET Core and has given us feedback. We know that tens of thousands of you have been using the pre-1.0 product. Thanks! We’ve received a lot of feedback about design choices, user experience, performance, communication and other topics. We’ve tried our best to apply all of that feedback. The release is much better for it. We couldn’t have done it without you. Thanks!
If you are not a .NET developer or haven’t used .NET in a while, now is a great moment to try it. You can enjoy the productivity and power of .NET with no constraints, on any OS, with any tool and for any application. All of that fully open source, developed with the community and with Microsoft’s support. Check out dot.net to see the breadth of .NET options.
Community Contribution
This is a huge milestone and accomplishment for the entire .NET ecosystem. Nearly 10k developers contributed to .NET Core 1.0. We never imagined that many folks contributing to the product. We’ve also been impressed by the quality of the contributions. There are significant components that the community is driving forward. Nice work, folks!
We also found that another 8k developers are watching these same repos, which effectively doubles the count. We believe that these developers watch these repos to either find that first opportunity to contribute or want to stay up-to-date on the project as part of their approach to .NET Core adoption.
At this point, nearly half of all pull requests for .NET Core related projects (e.g. corefx, coreclr) come from the community. That’s up from 20% one year ago. The momentum has been incredible. Check out the set of developers who contributed pull requests that were merged to the product. Thanks!
Here’s the breakdown of developers that created pull requests, created issues or made comments in any one of the .NET Core related repos, per organization, as determined by using the GitHub API:
| User Count | Organization | Example repo |
|---|---|---|
| 5176 | aspnet | mvc |
| 3804 | dotnet | corefx |
| 2124 | nuget | NuGet.Client |
| 560 | microsoft | visualfsharp |
Total unique users: 9723
Note: The counts don’t sum to the total because some users contribute to multiple organizations (thanks!) and we’ve tried to avoid double-counting.
Note: The counts from the Microsoft org are specific to the few .NET Core-related repos that exist there, such as visualfsharp.
Note: These numbers include Microsoft employees, which are (at most) 10% of the count.
Samsung joins the .NET Foundation
Increased interest in .NET Core has also driven deeper engagement in the .NET Foundation, which now manages more than 60 projects. Today we are announcing Samsung as the newest member. In April, Red Hat, Jet Brains and Unity were welcomed to the .NET Foundation Technical Steering Group.
“.NET is a great technology that dramatically boosts developer productivity. Samsung has been contributing to .NET Core on GitHub – especially in the area of ARM support – and we are looking forward to contributing further to the .NET open source community. Samsung is glad to join the .NET Foundation’s Technical Steering Group and help more developers enjoy the benefits of .NET.” Hong-Seok Kim, Vice President, Samsung Electronics.
The contributions from Samsung have been impressive. They have a great team of developers that have taken an interest in .NET Core. We’re glad to have them as part of the larger team.
.NET Core Usage
Some customers couldn’t wait until the final 1.0 release and have been using preview versions of .NET Core in production, on Windows and Linux. These customers tell us that .NET Core has had a significant impact for their businesses. We look forward to seeing many of the applications that will get built over the next year. Please keep the feedback coming so that we can decide what to add next.
Illyriad Games, the team behind Age of Ascent, reported a 10-fold increase in performance using ASP.NET Core with Azure Service Fabric. We are also extremely greatful for their code contributions to this performance. Thanks @benaadams!
NetEase, a leading IT company in China, provides online services for content, gaming, social media, communications and commerce, needed to stay on the leading edge of the ever-evolving mobile games space and chose .NET Core for their back end services. When compared to their previous Java back-end architecture: “.NET Core has reduced our release cycle by 20% and cost on engineering resources by 30%.” When speaking about the throughput improvements and cost savings: “Additionally, it has made it possible to reduce the number of VMs needed in production by half.”
We used industry benchmarks for web platforms on Linux as part of the release, including the TechEmpower Benchmarks. We’ve been sharing our findings as demonstrated in our own labs, starting several months ago. We’re hoping to see official numbers from TechEmpower soon after our release.
Our lab runs show that ASP.NET Core is faster than some of our industry peers. We see throughput that is 8x better than Node.js and almost 3x better than Go, on the same hardware. We’re also not done! These improvements are from the changes that we were able to get into the 1.0 product.
.NET developers know that the platform is a great choice for productivity. We want them to know that it’s also a great choice for performance.
.NET Core 1.0
We’ve been talking about .NET Core for about two years now, although it has changed significantly over that time. It’s good to recap in this post what defines and is included in .NET Core 1.0.
.NET Core is a new cross-platform .NET product. The primary selling points of .NET Core are:
- Cross-platform: Runs on Windows, macOS and Linux.
- Flexible deployment: Can be included in your app or installed side-by-side user- or machine-wide.
- Command-line tools: All product scenarios can be exercised at the command-line.
- Compatible: .NET Core is compatible with .NET Framework, Xamarin and Mono, via the .NET Standard Library.
- Open source: The .NET Core platform is open source, using MIT and Apache 2 licenses. Documentation is licensed under CC-BY. .NET Core is a .NET Foundation project.
- Supported by Microsoft: .NET Core is supported by Microsoft, per .NET Core Support
Composition
.NET Core is composed of the following parts:
- A .NET runtime, which provides a type system, assembly loading, a garbage collector, native interop and other basic services.
- A set of framework libraries, which provide primitive data types, app composition types and fundamental utilities.
- A set of SDK tools and language compilers that enable the base developer experience, available in the .NET Core SDK.
- The ‘dotnet’ app host, which is used to launch .NET Core apps. It selects and hosts the runtime, provides an assembly loading policy and launches the app. The same host is also used to launch SDK tools in the same way.
Distributions
There are two main distributions for .NET Core:
- .NET Core – Includes the .NET Core runtime and framework. The current version is “.NET Core 1.0”
- .NET Core SDK – Includes .NET Core and the .NET Core Tools. The current version is “.NET Core SDK 1.0 Preview 2”.
The .NET Core Tools are considered “Preview” currently. We chose “Preview” because we are not yet done shaping the tools. We know that there are still some changes coming. It’s not a quality statement. We’re quite happy with the quality and use the .NET Core tools ever day as part of our engineering system.
Most people will want to get the .NET Core SDK from dot.net/core. You can, however, check out our latest builds, where it’s easy to see the two different distributions.
Workloads
By itself, .NET Core includes a single application model — console apps — which is useful for tools, local services and text-based games. Additional application models have been built on top of .NET Core to extend its functionality, such as:
.NET Core Tools
You typically start .NET Core development by installing the .NET Core SDK. The SDK includes enough software to build an app. The SDK gives you both the .NET Core Tools and a copy of .NET Core. As new versions of .NET Core are made available, you can download and install them without needing to get a new version of the tools.
Apps specify their dependence on a particular .NET Core version via the project.json project file. The tools help you acquire and use that .NET Core version. You can switch between multiple apps on your machine in Visual Studio, Visual Studio Code or at a command prompt and the .NET Core tools will always pick the right version of .NET Core to use within the context of each app.
You can also have multiple versions of the .NET Core tools on your machine, too, which can be important for continuous integration and other scenarios. Most of the time, you will just have one copy of the tools, since doing so provides a simpler experience.
The dotnet Tool
Your .NET Core experience will start with the dotnet tool. It exposes a set of commands for common operations, including restoring packages, building your project and unit testing. It also includes a command to create an empty new project to make it easy to get started.
The following is a partial list of the commands.
- dotnet new – Initializes a sample console C# project.
- dotnet restore – Restores the dependencies for a given application.
- dotnet build – Builds a .NET Core application.
- dotnet publish – Publishes a .NET portable or self-contained application.
- dotnet run – Runs the application from source.
- dotnet test – Runs tests using a test runner specified in the project.json.
- dotnet pack – Creates a NuGet package of your code.
dotnet works great with C# projects. F# and VB support is coming.
.NET Standard Library
The .NET Standard Library is a formal specification of .NET APIs that are intended to be available on all .NET runtimes. The motivation behind the Standard Library is establishing greater uniformity in the .NET ecosystem. ECMA 335 continues to establish uniformity for .NET runtime behavior, but there is no similar spec for the .NET Base Class Libraries (BCL) for .NET library implementations.
The .NET Standard Library enables the following key scenarios:
- Defines uniform set of BCL APIs for all .NET platforms to implement, independent of workload.
- Enables developers to produce portable libraries that are usable across .NET runtimes, using this same set of APIs.
- Reduces and hopefully eliminates conditional compilation of shared source due to .NET APIs, only for OS APIs.
.NET Core 1.0 implements the standard library, as does the .NET Framework and Xamarin. We see the standard library as a major focus of innovation and that benefits multiple .NET products.
Support
.NET Core is supported by Microsoft. You can use .NET Core in a development and deploy it in production and request support from Microsoft, as needed. Each release also has a defined lifecycle, where Microsoft will provides fixes, updates, or online technical assistance.
The team adopted a new servicing model for .NET Core, with two different release types:
- Long Term Support (LTS) releases
- Typically a major release, such as “1.0” or “2.0”
- Supported for three years after the general availability date of a LTS release
- And one year after the general availability of a subsequent LTS release
- Fast Track Support (FTS) releases
- Typically a minor release, such as “1.1” or “1.2”
- Supported within the same three-year window as the parent LTS release
- And three months after the general availability of a subsequent FTS release
- And one year after the general availability of a subsequent LTS release
Some customers want to deploy apps on very stable releases and do not want new features until the app is developed again. Those customers should consider LTS releases.
Other customers want to take advantage of new features as soon as possible, particularly for apps that are almost always in development. Those customers should consider FTS releases.
Note: We haven’t released an FTS verion yet. .NET Core 1.0 is an LTS version.
.NET Core Tools Telemetry
The .NET Core tools include a telemetry feature so that we can collect usage information about the .NET Core Tools. It’s important that we understand how the tools are being used so that we can improve them. Part of the reason the tools are in Preview is that we don’t have enough information on the way that they will be used. The telemetry is only in the tools and does not affect your app.
Behavior
The telemetry feature is on by default. The data collected is anonymous in nature and will be published in an aggregated form for use by both Microsoft and community engineers under a Creative Commons license.
You can opt-out of the telemetry feature by setting an environment variable DOTNET_CLI_TELEMETRY_OPTOUT (e.g. export on OS X/Linux, set on Windows) to true (e.g. “true”, 1). Doing this will stop the collection process from running.
Data Points
The feature collects the following pieces of data:
- The command being used (e.g. “build”, “restore”)
- The ExitCode of the command
- For test projects, the test runner being used
- The timestamp of invocation
- The framework used
- Whether runtime IDs are present in the “runtimes” node
- The CLI version being used
The feature will not collect any personal data, such as usernames or emails. It will not scan your code and not extract any project-level data that can be considered sensitive, such as name, repo or author (if you set those in your project.json). We want to know how the tools are used, not what you are using the tools to build. If you find sensitive data being collected, that’s a bug. Please file an issue and it will be fixed.
We use the MICROSOFT .NET LIBRARY EULA for the .NET Core Tools, which we also use for all .NET NuGet packages. We recently added a “DATA” section re-printed below, to enable telemetry from the tools. We want to stay with one EULA for .NET Core and only intend to collect data from the tools, not the runtime or libraries.
Using .NET Core 1.0
You can build .NET Core apps with Visual Studio, Visual Studio Code or at the command-line. Visual Studio Code is the newest experience for building .NET apps. Let’s take a look at building .NET Core apps with it.
Using Visual Studio Code
Show the experience using Visual Studio Code.
To get started with .NET Core on Visual Studio Code, make sure you have downloaded and installed:
You can verify that you have the latest version of .NET Core installed by opening a command prompt and typing dotnet --version. Your output should look like this:
Next, you can create a new folder, scaffold a new “Hello World” C# application inside of it with the command line via the dotnet new command, then open Visual Studio Code in that directory with the code . command. If you don’t have code on your PATH, you’ll have to set it.
If you don’t have C# language plugin for Visual Studio Code it installed already, you’ll want to do that.
Next, you’ll need to create and configure the launch.json and tasks.json files. Visual Studio Code will have asked if it can create these files for you. If you didn’t allow it to do that, you will have to create these files yourself. Here’s how:
-
- Create a new folder at the root level called
.vscodeand create thelaunch.jsonandtasks.jsonfiles inside of it. - Open
launch.jsonand configure it like this:
- Create a new folder at the root level called
-
- Open the
tasks.jsonfile and configure it like this:
- Open the
- Navigate to the Debug menu, click the Play icon, and now you can run your .NET Core applications!
Note that if you open Visual Studio code from a different directory, you may need to change the values of cwd and program in launch.json and tasks.json to point to your application output folders.
You can also debug your application by setting a breakpoint in the code and clicking the Play icon.
Comparison with .NET Framework
The major differences between .NET Core and the .NET Framework:
- App-models — .NET Core does not support all the .NET Framework app-models, in part because many of them are built on Windows technologies, such as WPF (built on top of DirectX). The console and ASP.NET Core app-models are supported by both .NET Core and .NET Framework.
- APIs — .NET Core contains many of the same, but fewer, APIs as the .NET Framework, and with a different factoring (assembly names are different; type shape differs in key cases). These differences currently typically require changes to port source to .NET Core. .NET Core implements the .NET Standard Library API, which will grow to include more of the .NET Framework BCL APIs over time.
- Subsystems — .NET Core implements a subset of the subsystems in the .NET Framework, with the goal of a simpler implementation and programming model. For example, Code Access Security (CAS) is not supported, while reflection is supported.
- Platforms — The .NET Framework supports Windows and Windows Server while .NET Core also supports macOS and Linux.
- Open Source — .NET Core is open source, while a read-only subset of the .NET Framework is open source.
While .NET Core is unique and has significant differences to the .NET Framework and other .NET platforms, it is straightforward to share code, using either source or binary sharing techniques.
Closing
Thanks for all the feedback and usage. It’s been a pleasure to build .NET Core and see so many people try it out. We really appreciate it. Please continue exploring the product and learning what it’s capable of.
We’ll update the .NET Core Roadmap as we have clear plans for upcoming versions.
Thanks for being part of the .NET community!
Make sure you have VS 2015 Update 3 before installing the VS package: https://www.visualstudio.com/news/releasenotes/vs2015-update3-vs
Thanks for the heads up!
The beginning of the post should say “Entity Framework Core 1.0”, not “Entity Framework 1.0”. Please update, thank you.
Fixed. Thanks!
Is it done yet? Hahaha… great to see that it finally is. 🙂 Congratulations to the entire team, and to the rest of us that will be using it for the next decade, and beyond!
Congratz
This is the best news I’ve had all year! Thank you so much to everyone, though I feel I can safely say that the journey is just beginning!
Glad the news and the release makes you happen. Agree … just the beginning.
This is great news! Looking forward to F# support 🙂
Me, too. It’s close.
It’s great news, lets do some tests 🙂
Great Work Guys! Waited eagerly for it.
ASP.NET Core 1.0 RTM Announements Talking about Breaking Changes:
https://github.com/aspnet/Announcements/issues?q=is%3Aopen+is%3Aissue+milestone%3A1.0.0
Is there a new IIS hosting installation available for Core 1.0? The docs link you to an RC2 version – is that still compatible with the 1.0 release?
There is a new ASP.NET Core Module available with this release that ships as part of the .NET Core Windows Server Hosting bundle: https://go.microsoft.com/fwlink/?LinkId=817246. I will make sure we get our stale doc links updated.
Thank you!
The .NET Standard Library link under the .NET Core 1.0 heading is broken (https://docs.microsoft.com/dotnet/articles/standard/library.md), can you please update?
Fixed. Sorry! Thanks for reporting.
Woohoo! Now we need the rest of the world to catch up! Any clue on when Swagger/Swashbuckle and Autofac will have their .NET Core releases?
Many projects have been waiting for our v1 release. I expect we’ll see more activity now.
How nuget packages will be supported with .net core projects?
Can we filter out by “supported by .net core” or there will be whole new package platform for this?
Great question. There isn’t an awesome experience yet.
Here’s an example: https://www.nuget.org/packages/Newtonsoft.Json/. Notice that it supports .NETStandard 1.0. That tells you it will work for .NET Core apps and libraries.
I created an issue for this: https://github.com/dotnet/core-docs/issues/678
What is the proper way to target the .NETStandard Framework? Will there be a .NETStandard 1.0 targeting pack for Visual Studio?
Thanks.
For anyone else interested, I found this tutorial that helps to answer the question:
https://docs.microsoft.com/en-us/dotnet/articles/core/tutorials/libraries
I find this tool to be super-extra-useful to explore what a package supports: https://github.com/NuGetPackageExplorer/NuGetPackageExplorer
Thank you .NET team… Really appreciate your efforts. In my view, it will soon become an ultimate framework & toolset to develop lightweight and powerful cloud apps. Want to see the Xamarin sharing the more and more of common capabilities very soon.
Glad you are happy. We are working closely with the Xamarin folks. A major goal is to make the common experiences the same and better for both.
Thank you .NET team. There is no other platform I would consider for my projects. *handshake *thank you
Just upgraded from RC2 and my website with 150+ EF7 objects is smoking fast now. Thank you so much for the performance enhancement work. It is really is appreciated.
BTW, if you put the MyModelBinderFactory work around for the RC2 enhancement issue (Ref: https://github.com/aspnet/Mvc/issues/4666), don’t forget to remove it after upgrade. Also If you have a project already, open the global.json file and change the .net version to “1.0.0-preview2-003121”. Then do package updates in nuget.
My debug startup times were about 20 seconds to home page and first hit to EF7 db call was about 30 seconds. Now they are 14 seconds and 5 seconds!
Those times are much higher than we’d hope. Can we chat about it? I’m rlander@ms.
Same error as last time. I think it’s because I’m behind a corporate proxy.

@LachlanB –
I believe you are running an older version of dotnet.exe
After I’ve uninstalled earlier versions, and installed the .NET Core SDK (see http://dot.net), I see the following version of dotnet.exe:
c:\hw>dotnet –version
1.0.0-preview2-003121
After you update to the latest bits, if you still see a problem with dotnet restore, we’d like to hear it. If so, please file an issue at http://github.com/nuget/home/issues
Thanks, Rob
NuGet team
I’m pretty sure that’s a really old version. Can you uninstall .NET Core and re-install?
This is the version # on my machine: 1.0.0-preview2-003121
Awesome….
Congratulations guys!
First of all, congratulations on the release!
I’m really looking forward to how this continues to develop.
Previously I’ve cloned the repository and built my own copy a few dozen times over the last year.
While this works great in setting up a development environment, it should not be a required step once released.
However, I am having trouble finding all of the required components.
I would expect the binaries to be available here:
https://github.com/dotnet/coreclr/releases
But alas only the source is available.
I don’t want an installer, so after jumping through several hoops, I found the binaries here:
https://www.microsoft.com/net/download#core
After extracting this, it appears that,
1) There are no symbol files, for either the CoreClr or CoreFX.
2) There is no debug build.
So I guess I’ll need to sync with Github again to build my own copy.
Improvements here would be greatly welcome!
Congrats on this amazing milestone. Two notes:
1) A note: I was having trouble following along with the debugging step in VS Code, until I tried updating the C# plugin to TODAY’s release (6/27/16). You can do this using [Ctrl+P] and then “ext install csharp”
2) A comment: The “File->New…” experience is quite different to .NET 4.X, and a little more guidance around adding .NET library dependencies would be helpful. For example, I was getting compiler errors when I wrote my first line of code in the body of Program.Main, “var dcs = new System.Runtime.Serialization.DataContractSerializer();” until I realized that each of these is now a NuGet package. I remembered reading that it was redesigned as “opt-in” but it still took me some time to figure out what was going on. In my case, it was even more confusing, because I added the NuGet that corresponded to my namespace (System.Runtime.Serialization), and even that wasn’t enough, as I needed to bring in System.Runtime.Serialization.Xml. This makes sense from a design perspective – I like it a lot – but it clearly needs more tooling for us dark matter developers, and I’m sure (or at least hope) this is on the roadmap.
Congratulations….Well Done Team.
how to set proxy in dotnet core cli?
something wrong with “dotnet restore”,
error info:
error: Unable to load the service index for source https://dotnet.myget.org/F/dotnet-core/api/v3/index.json.
error: Response status code does not indicate success: 407 (Proxy Authentication Required).
Hi Jeffrey, you can add proxy settings to your nuget.config file. I’d also suggest you install cntlm and try.
Hi Ronan
thanks, preview 2 can fix proxy problem. the proxy settings which I had put it in nuget.config
wow, it’s so excited, we will try our first .net core 1.0 project as soon as quickly
Great Work ! Congratz guys!
Really happy with the news, have been desperately waiting for the final production release. The team had been doing its best to convince all our customers to move to Cloud using ASP.NET Core since last 6 months (after RC 1 release) and even delayed delivery of some of the projects because of the delay in release date. 🙁
Anyways all is well that ends well, now waiting desperately for the support for ASP.NET Core Apps in Azure Cloud Services. 🙂
Congratulations to the team. (y) 🙂
Wonderful news!
Congratulation !!! I’ve been waiting this excited news for long time !!! Hope that new move of .net will be BIG !!!
Congratulations! Great milestone!
System.Reflection.Emit – version 4.0.1
System.Reflection.TypeExtensions – 4.1.0
Are you serious?
Can you elaborate on the concern?
Here’s an explanation: https://docs.microsoft.com/en-us/dotnet/articles/core/versions/index#packages
Great! We are to see a stable ARM release soon as well! 🙂
ARM is an important CPU target for the project. We don’t have a specific date so far on it.
milestone!
Thank you .NET team. You all are awesome. #handshake #thankyou
So is dotnet-dev-1.0.0-preview2-003121 supposed to be RTM or are the directions not updated? Ubuntu directions BTW.
Yeah, I’m really confused by this as well. I tried to just install 1.0.0 instead of the -preview2-003121 but it didn’t work, so idk.
“Preview” is for some of the tooling, which will RTM later. .NET Core itself is 1.0.
Correct. We need to update our docs on this topic. I agree that it isn’t intuitive.
Yeah, the naming/numbering is pretty difficult to follow but the preview2-003121 really is the one you want. It contains the RTM of Core 1.0.0 runtime, and the “preview 2” of the tooling (dotnet command line, etc.) If you look at the Ubuntu repo packages you’ll actually see lots of “rc2” and “preview3” packages but those are nightlies that came before & after (respectively) this announcement. The 003121 build number seems to be the magic number for all platforms.
http://stackoverflow.com/questions/38104390/install-update-net-core-1-0-on-ubuntu-which-package-version
And what about ARM support like Windows 10 IoT on Raspberry Pi 3? When it is planned? Thanks 😉
Maybe 1.1.0
https://github.com/aspnet/Home/issues/1685
Fedora 24,
Failed to initialize CoreCLR, HRESULT: 0x80131500
Up. Would it possible to add instructions for Fedora 24 on https://www.microsoft.com/net/core#fedora ?
By the way, great work.

Hi guys,
I’ve been having the same problem…
Could you help me with install .Net Core in Fedora 24????
Fedora 24 has libraries too new to work with .NET Core – for now you have to stick with Fedora 23…
You can see the list and the status of the OSes supported…

well Fedora 25 is on the map for release now.. so would be nice if this could be addressed sometime soon.
vscode 1.4 is now available and things are looking good.. just need to hop on that 🙂
Congratulations Microsoft Team.
Congratulations Guys.
It’s a great news. thanks .net core team.
Congratulations, Great News..
Good Job,
Waiting for new things…
Getting confusion about .net core please clarify me !!!
Before .Net core1.0 introduced June 27th; in 2015 MS announced a version called as .net core 5.0 and Asp.net core 5.0.
Resource where i found above information :-
https://blogs.msdn.microsoft.com/cesardelatorre/2014/11/18/what-is-net-core-5-and-asp-net-5-within-net-2015-preview/
So my question is if MS announced .Net core 1.0 in last week then what about .Net core 5.0 mention in that blog ?
Is it beta version ?
If yes then why the name again 5.0 not 1.0 .
Please clarify me.
Take a look: http://www.hanselman.com/blog/ASPNET5IsDeadIntroducingASPNETCore10AndNETCore10.aspx

Anyone able to use the code generator to create a view after the upgrade?
“There was an error running the selected code generator” No executable found matching command ‘dotnet-asp net-code generator'”
It worked prior to the upgrade for me.

Around 7 or 8 years ago I started using .Net and used it as my main development platform for around 3 years. Then the market evolved, and in comparison .Net was bulky, Windows-only, too closed, new frameworks were way more complicated than they should be (looking at you WCF), you had many ways to achieve the same thing (like concurrent programming), Visual Studio was too expensive, and I could go on and on. I saw it as a project without a future, and migrated to other frameworks, like Ruby/Rails, then NodeJs, then Go.
A few months ago though I watched Microsoft Build and I was surprised to say it was the first time in many years that I was excited about anything related to .Net. .Net Core and friends (ASP.Net/EF) solved basically all the problems by killing the monsters that were the old versions and starting over. I have been happily using the Core products almost full-time since then and I’m pretty sure .Net will once again become my primary development platform. Great work Microsoft!
Everything was fine and dandy until i got to this part “.NET Core Tools Telemetry”! opting out means many users wouldn’t know about it! you really need to make it crystal clear or have an option to somehow acknowledge users that they are taking part in this experiment! wtf is wrong with you? stop being so intrusive!
Can someone explain why it takes hours to install ?
Thanks for confirming. I thought it was because I was installing on a wimpy 1.6 GHz laptop with 4GB ram. The progress bar didn’t move for so long was ready to cancel, convinced something was wrong. Now it has at least inched (or more accurately millimeter-ed) .
What exactly are you guys installing?
It took me seconds to install the framework. The SDK was also very quick.
The longest for was the Visual Studio 2015 Update 3, that actually caused a BSOD closer to the end of the install and left Visual Studio in disarray. I actually had to uninstall Visual Studio, and then install it from scratch, before installing the tooling preview. Tooling preview install was not quick, but definitely under an hour.
What about the removal of the project.json file, breaking change even after the 1.0 ? do we need to wait for it before creating new projects in .NET core ?
I’m a bit confused.
I think the idea is that project.json will be automatically converted to whatever supersedes it. Not entirely sure how that will play out for projects that target multiple frameworks…

You Microsoft are truly arrogant. What Oracle Java is better than yours is that Oracle Java never drops down APIs, they just mark them as deprecated. I suggest that you DON’T DEVELOP .NET CORE ANY MORE, JUST FORK MONO AND DEVELOP, make it more like a Microsoft software.

During a planning meeting today an issue came up, which could be a show stopper. It appears that the new configuration system is built around JSON. We have been using SlowCheetah and the Web.config translation tools for our different builds. Does .NET Core, or its tooling, have a translation system for the JSON configuration files?
no
