net5.0-windows fails because of WPF/XAML bug

[archi-Doc]

Hi,
I tried ThisAssenbly for a console app, and it worked perfectly.
But didn't work for a windows app.

error CS0103: The name 'ThisAssembly' does not exist in the current context

csproj file is

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net5.0-windows</TargetFramework>
    <UseWPF>true</UseWPF>
    <LangVersion>9.0</LangVersion>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="ThisAssembly" Version="1.0.0" />
  </ItemGroup>

</Project>

Looks like ThisAssemly generates correct code and I can see the generated code, but windows app can't reference those code.

This is due to a bug in WPF: dotnet/wpf#3404.
The workaround is https://docs.microsoft.com/en-us/aspnet/core/grpc/troubleshoot?view=aspnetcore-3.0#wpf-projects-unable-to-generate-grpc-c-assets-from-proto-files (basically use a class library instead, quite the #fail).

Since this is not something we can fix in this project, I'm going to tentatively close it. Please do reopen if there is an actual fix at some point and we need to do something on this project.

Thanks!

This search shields a potential manual workaround alternative for your own repo: https://github.com/dotnet/arcade/search?q=_WpfTempProjectNuGetFilePathNoExt

Thanks for the reply.
I'll wait for Microsoft to resolve this issue.

Doesn't work within Blazor(server) apps as well.

@springy76 could you link to the relevant MS issue on their side too, in case they are aware, so others can also track that as needed?
