BenchmarkDotNet fail in WPF project with .NET 5.0-windows target

[lindexi]

Step:

1. Create a WPF project
2. Add BenchmarkDotNet package
3. Add and run any Benchmark code

Running the Benchmark code that we can find error NU1201: Project Benchmark is not compatible with net5.0 (.NETCoreApp,Version=v5.0). Project Benchmark supports: net5.0-windows7.0 (.NETCoreApp,Version=v5.0)

Hi @lindexi

This problem has been already reported (#1535) and fixed (#1560) but we just have not released new version to NuGet.org

To get it working today you need to use the latest preview version from our CI feed: https://benchmarkdotnet.org/articles/guides/nuget.html#nightly

Thanks,
Adam

Thank you @adamsitnik

@adamsitnik I just hit this same problem.
Switching to the nightly 0.12.1.1527 did not help.
Suggestions? Thanks! :)

[adamsitnik]

@raffaeler is there a chance you could create a small GitHub repo with a repro?

[raffaeler]

Hi Adam, the project looks like straightforward.
Could you try this project configuration first?

All I do is just calling BenchmarkRunner.Run<MyBenchmark>(); with a very simple test.

<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>net5.0-windows10.0.19041.0</TargetFramework>
        <Platforms>x64;x86</Platforms>
    </PropertyGroup>

    <ItemGroup>
        <PackageReference Include="Microsoft.VCRTForwarders.140" Version="1.0.7" />
    </ItemGroup>

    <ItemGroup>
        <PackageReference Include="BenchmarkDotNet" Version="0.12.1.1527" />

        <!-- C# projection of my C++ library -->
        <PackageReference Include="WinNativeUtilities" Version="1.0.412.163840" />
    </ItemGroup>
</Project>

@raffaeler I was able to repro, sent the fix in #1691 I am sorry for the delay but recently I've been 100% busy ;/

[raffaeler]

@adamsitnik no worries, I totally understand, I am also on several projects and it's difficult to multiplex the time
Hope to meet in some conference before or later, toasting with beers :)
