Release of SDK 2.7.198 and Runtime 5.7.198 for Windows

Service Fabric version 5.7 of the runtime and 2.7 of the SDK is now available, packed with new features, improvements, and bug fixes for containers, SDK, Reverse Proxy, and the core system itself.

Some highlights of this release:

Run Reliable Services and Reliable Actors in Windows Containers (Preview)

Reliable Services and Reliable Actors can now be packaged and run in Windows containers. This feature is currently **in preview**, with Visual Studio integration planned for an upcoming release.

Assign unique IP addresses to services and containers with open networking mode

In addition to the default “nat” networking mode, Service Fabric now supports “open” networking mode. This mode allows each Service Fabric service - whether it's in a container or not - to get a dynamically assigned IP. Thus, with this feature, you can have multiple services listening on the same port.

ASP.NET Core 2.0 support

The Microsoft.ServiceFabric.AspNetCore.* NuGet packages now support ASP.NET Core 2.0.
Note that only stable builds of ASP.NET Core 2.0 packages are supported; pre-release/preview builds (for example, v2.0.0-preview2-final) of ASP.NET Core 2.0 are not guaranteed to work properly. A final stable build of ASP.NET Core 2.0 packages should be available on NuGet soon.
Also note that the ASP.NET Core WebListener package has been renamed to HttpSys in ASP.NET Core 2.0. Support in Service Fabric for the new HttpSys package is not available yet in this release, but is coming soon. See the full release notes for more details on this.

A consistent cluster configuration between your local development cluster, standalone clusters, and Azure clusters

The cluster configuration for a local development cluster now uses the same clustersettings.json format that a standalone cluster uses, instead of the older ClusterManifest.xml format. This is also more closely aligned with Resource Manager templates for Azure clusters, which has similar settings to clustersettings.json. This will make it much easier to configure a local development cluster to resemble a production cluster, because the configuration format is identical for standalone clusters and more similar to Azure clusters.

Ability to send urgent health reports to the cluster immediately

You can now send urgent health reports to the cluster immediately without waiting for the usual batch send interval. This is very useful in situations where a process crash is imminent, like during unhandled exceptions, where there isn't time to wait for the next batch send interval.

As always, be sure to read through the full release notes for a complete list of new features, improvements, and bug fixes.

See you at our upcoming Service Fabric Community Q&A on August 17th @ 10AM PST. Check back on this blog for more details.

    I have created a custom FabricTransportServiceRemotingProviderAttribute for my project, and your latest updates have broken my code.
    More specifically, in my IServiceRemotingListener.CreateServiceRemotingListener implementation, when I try to return a new FabricTransportServiceRemotingListener instance by passing the service Context and a custom ServiceRemotingDispatcher, I get this:

    The error is: Method not found: ‘System.String System.Fabric.ServiceContext.get_ListenAddress()’.
    at Microsoft.ServiceFabric.Services.Remoting.FabricTransport.Runtime.FabricTransportServiceRemotingListener..ctor(ServiceContext serviceContext, IServiceRemotingMessageHandler messageHandler, FabricTransportRemotingListenerSettings listenerSettings)

    Please inform me as soon as possible about what I can do to rectify the problem.

    1. Hi George – please open an issue here: – I’ve informed the engineers and they will look for your issue and respond. Thanks.

      1. Please make sure that the NuGet packages you are using is same or older version than the runtime. E.g. NuGet packages version 5.7 are not supported on clusters running 5.6 or older.

        1. George Gkionis says:

          I’ve managed to download the latest SF SDK (5.7.x), and the behavior returned to normal.

  2. Tomasz Sobkowiak says:

    Exactly the same problem here as George Gkionis mentioned – were there any changes to that?

    1. George Gkionis says:

      Download and install the latest SF SDK (5.7.x).

  3. All links inside DOC file are ending up in HTTP 404 (for example link below in document supposed to tell about new networking mode) which ends up in HTTP 404

    1. The docs are pending publishing and will be available soon.

  4. Hans Ravnaas says:

    The link for “Service Fabric networking modes” in the release notes seems to be incorrect. Returns a 404.

    1. Please see my comment above – The docs are pending publishing and will be available soon.

    Thanks Service Fabric team for completely breaking all my service fabric applications with the nuget updates in this release. I have reverted the whole thing.

    1. What specifically broke? Did you update both the cluster and NuGets? New NuGets will not work with older runtime.

      1. Vijay says:

        After spending a bit more time – it got fixed after I deployed compiling in x64 mode. Previously would work even if the solution was set to AnyCPU. But, this is hit or go. I guess x64 works reliably all the time.

        My workers were erroring out for no apparent reason. Some strange, meaningless error indicating service could not start. Also, when I deployed multiple times in this state, once it failed because it could not read the configuration defined in the application parameters xml file.

        1. Thanks for reporting back Vijay, glad you got it working.

    Updated to the newest VS 2017 SDK but the tools version didn’t update. Will tools be updated separately as VS extension or is there something I am missing?

    1. Nick Randell says:

      I’m seeing errors such as “Unable to find version 1.6.1 of package ‘Microsoft.VisualStudio.Azure.Fabric.MSBuild'”
      nuget only has version 1.6.0

      1. There you go, that was a miss – sorry for the inconvenience.

        FYI the NuGet packages are also distributed with the SDK and tooling.
        SDK: C:\Program Files\Microsoft SDKs\Service Fabric\packages
        Tooling: C:\Program Files (x86)\[VS Version]\Common7\IDE\Extensions\Microsoft\Service Fabric Tools

    2. Visual Studio 2017 Update 3 (15.3) has the tooling version 1.7. For Visual Studio 2015, the updated tooling is available via Web Platform Installer. The 1.6 version of the tooling will still work with the updated SDK.

      1. Juho Hanhimäki says:

        That explains. I am still on 2017 15.2. Would be nice if stuff like this was documented.

    Hi. I have problem with reverse proxy. When i try to browse reverse proxy url (localhost:19081/myapp/myservice) after 60 seconds i get 504 gateway timeout. I tried increase timeout value with Timeout= in url but i get timeout after specified time. I can browse local service url (localhost:808x) and it works. I have cluster with two VMs running Windows server 2016, CodeVersion:, i used this template
