[BUG] Failing to Build WPF Project #140

Closed drepamig closed 2 years ago

drepamig commented 2 years ago

Describe the bug This behavior happened on a more developed project, but I'm able to reproduce it on a new WPF project.

In a nutshell, I'm unable to build a project when Splat.DependencyInjection.SourceGenerator is included in the project. When I do, I get the following errors:

The curious thing is this used to work just fine on version 1.1.33 but now, when I revert, it still doesn't work. I've rolled back to an older commit on my main project that DID work, but it still won't build. This leads me to believe it's something with NET6. I'm on SDK 6.0.400. I would have likely been on 6.0.300 when I last had a successful build, but I have not yet tested that theory.

Steps To Reproduce

Failing Example Project: WpfApp1.zip

Provide the steps to reproduce the behavior:

  1. Create WPF C# App targeting NET 6
  2. Add ReactiveUI nuget packages: 
    <ItemGroup>
    <PackageReference Include="ReactiveUI" Version="18.3.1" />
    <PackageReference Include="ReactiveUI.Events.WPF" Version="15.1.1" />
    <PackageReference Include="ReactiveUI.Fody" Version="18.3.1" />
    <PackageReference Include="ReactiveUI.WPF" Version="18.3.1" />
    <PackageReference Include="Splat.DependencyInjection.SourceGenerator" Version="1.1.69">
        <PrivateAssets>all</PrivateAssets>
    </PackageReference>
</ItemGroup>
  3. Build
  4. See error

Expected behavior It should build.

This is a known dotnet bug at the moment
