Silverlight 1.0 RC1 is Here!


As indicated in a previous post, we’re homing in on the launch of Silverlight 1.0, and today marks another milestone with the launch of the first release candidate. Since the beta we released at MIX, we’ve fixed approximately 2000 bugs and work items and we’re now feature complete with the final JavaScript-based API. This version of the runtime is vastly more stable than the beta release: our stress test runs show improvements of two or three orders of magnitude in many cases, and the product demonstrates the polish one might expect from a near-final release.


Along with the 1.0 RC1 release, we’ve also refreshed the 1.1 bits. We’ve not exposed any significant changes in the .NET extensions, but the 1.1 “alpha refresh” includes the same core runtime as 1.0 RC1. A note on installation: if you have the beta release on your machine, there’s no need to uninstall – simply run the RC1 installer and it will overwrite the existing binaries on your machine.


Here’s the runtime itself:



Some tools for building Silverlight applications:



Inevitably (given that this release isn’t 100% compatible with the previous one, particularly as regards the object activation model), a lot of the samples out there today are broken. We’ve worked with a few folk that we know to help them prepare for this release, but if you have a Silverlight sample or site out there today based on the existing beta release, you’ll want to pick up the new silverlight.js and work through the breaking changes to move your site up to the new release. We won’t break you again, we promise!

    Hey,

    I got a few questions about the versioning scheme of SilverLight 1.1 in the assemblies. Hopefully you’ll be able to answer or to point me to someone :)

    In the first Alpha of SilverLight, the assemblies where versionned as 2.1.xxxx, now it’s 1.1.xxx. That’s ok, but in the assemblies, the version string of the metadata is still 2.0.50727, which is the version number of the .net 2 framework, so it’s somewhat confusing for tools dealing with assemblies. Do you plan to change that? Also, it looks like you incremented the CLI header version from 2.0 to 2.5. Do you plan any metadata layout change, or is it only for the sake of being able to distinguish SilverLight assemblies to normal assemblies? That would really help to have something consistent inside the metadata.

    Many thanks,

  11. tims says:

    zyborg, you might try the "direct link" hyperlink next to the Silverlight runtime entries, rather than the indirect links to the pages themselves; as mentioned, it will take a couple of hours to propagate through the download center but the direct link should work in the meantime.

  13. Jb Evain says:

    To add just another thing to my comment, it appears that the CLI header version has not been incremented, so my concern is mainly about the string version, that could be used to determine which version of the runtime this assembly is supposed to work on. It should really be something else that the version number of .net 2.0.

    Tim –

    What is the policy from here forward on Silverlight back compat?

    I am one of the folks with a dead site as of last night.  Will RC1 sites be supported by the Silverlight runtime when v1.0, v2.0 and v3.0 ship?  

    I like Silverlight a lot, but it was a rude surprise to have my site no longer visible at all after updating to the new runtime.

    Anybody else having problems with Image and MediaElement Elements pointing at http urls?

  43. tims says:

    Devin,

    It’s probably because we disable cross-domain file access. So for example, if your Silverlight page is hosted at a file:// location, you can’t reference images and media via an http:// moniker, and vice versa. You don’t have to host them on the site of origin, just reference them the same way.

    Hope this helps,

    Tim

  44. tims says:

    John, sorry about that – we did our very best to reach out to as many affected sites as we could, but it was hard to identify everyone. We’re done now – you should never be affected by this again. The API is fixed for v1; in the future, we wouldn’t break changes without introducing a new version that ran side-by-side.

  53. tims says:

    Dionysos, although it’s not sponsored or endorsed by Microsoft, the Mono project is producing a Silverlight implementation for Linux at present: http://www.mono-project.com/Moonlight#Getting_Started

    I think it’s challenging to make the case that Solaris is a "popular" OS, at least on the desktop.

    With the 1.1 release, we’ll support over 96% of machines on the internet (not including Moonlight) – the next 2% are Windows 9x, and then you’re into the long tail of operating systems with 0.x% market share, which includes Solaris. With >96% reach, I’d be surprised if this was the biggest blocker to adoption of Silverlight.

    I’m using these stats as a rough-and-ready reference: they broadly match our own research: http://marketshare.hitslink.com/report.aspx?qprid=2

  55. Mikko S. says:

    First of all, congratulations on getting the RC 1.0 out.

    Being totally new to the Silverlight, could someone fill me in on some basics?

    I read some of the technical documents from msdn and they all stated that I could use the Visual Studio tools for creating web pages that have Silverlight components. Are there any free tools that I could use instead? And how about the server side, do I have to have IIS server, or could I use e.g. Apache?

    Best regards.

  56. Tim,

    Why is the new refresh SDK 199 megs vs. the old SDK was only 7 meg?  

    …I guess

  57. tims says:

    Hi Corbin, the "new refresh" SDK includes the documentation and samples; whereas the "old" (preview) SDK was purely the Visual Studio template and a breaking change document.

  58. tims says:

    Mikko, yes – you absolutely can. All you need to build a Silverlight-based site is any text editor that can publish to the web. If you download the SDK, you’ll find a "silverlight.js" file that you need to include, which handles the Silverlight runtime activation, but otherwise, this is pretty straightforward. (Of course, if you want WYSIWYG XAML editing support, you’ll need something like Expression Blend.)

    Maybe I should put together a blog post that talks about this in more detail…
