Doesn't work with .NET IL trimming in WinUI 3 project #1734

Closed JasonWei512 closed 1 year ago

JasonWei512 commented 1 year ago

Description

If I enable .NET IL trimming in a WinUI 3 project, App Center SDK stops working. It cannot send any data to the server.

Repro Steps

SampleProject.zip

  1. Create an empty .NET 7 WinUI 3 project.

  2. Install App Center nuget packages and enable it in App.xaml.cs.

  3. Run the app, and I can see STARTSESSION in Log Flow on App Center's website.

    When the app tracks an event, I can also see it in Log Flow.

    In Fiddler I can see my app sending network requests to https://appcenter.ms/api.

  4. Enable .NET IL trimming. Add these lines in .csproj file.

    <PropertyGroup>
   <PublishTrimmed>true</PublishTrimmed>
   <TrimMode>partial</TrimMode>
   <BuiltInComInteropSupport>true</BuiltInComInteropSupport>
</PropertyGroup>

    Now when my app runs, I can't see anything in Log Flow.

    When the app tracks an event, I can see "System.MissingMethodException" in "System.Private.CoreLib.dll" in Visual Studio's debugger output.

    In Fiddler I can't see any network request to App Center server.

    I guess this is related to json serialization.

@AnatolyPristensky Any updates on this problem? What did the "internal board" decide?

As we do not have plans to add support for this feature in the next year, I'm closing the issue.
