Warning in extension project: warning : Some features may not work correctly, because the generation of the runtime configure file (*.runtimeconfig.json) has been disabled.

I get this warning (which was introduced by this PR) on a iOS extension:

/usr/local/share/dotnet/packs/Microsoft.iOS.Sdk/16.2.1024/targets/Xamarin.Shared.Sdk.targets(979,3): warning : Some features may not work correctly, because the generation of the runtime configure file (*.runtimeconfig.json) has been disabled. [/Users/.../ShareExtension/ShareExtension.csproj]

I have not set GenerateRuntimeConfigurationFiles to false, but when I set it to true explicitly, the warning disappears. On the main project, the warning does not show up, even without having to set GenerateRuntimeConfigurationFiles=false.
Is it safe to ignore the warning? Should I set GenerateRuntimeConfigurationFiles=false or does this have any unwanted side-effects?

@tipa I filed an issue, because we should solve this somehow.

My initial guess is that GenerateRuntimeConfigurationFiles defaults to false (or not set at all) because app extension projects are actually library projects, in which case the fix is probably to set GenerateRuntimeConfigurationFiles=true (and workaround would be to do that in your own project).

If you have a binlog you could upload that would be great!

The warning is easy to reproduce with dotnet publish -c Release, using this project: test.zip

Do you still need a binlog?

No need, thanks for the test project!
