Target framework: netcoreapp1.0

New test library project with 2 simple test classes, attempting to run "dotnet test" from command line yields exception:

@gyorgynadaban I am testing this using https://github.com/rprouse/NUnitPlatformTests , and can't repro. Can you check using the same repo, you should see 50 passed tests, 2 skipped and 2 failed.

@gyorgynadaban is your project multi-targetted? Can you post a copy of your CSPROJ file?

NUnit does depend on System.Runtime.InteropServices.RuntimeInformation. If you look at the adapter in NuGet, https://www.nuget.org/packages/NUnit3TestAdapter/ we depend on Microsoft.DotNet.InternalAbstractions which pulls in the System.Runtime.InteropServices.RuntimeInformation.

You've also added a reference to Microsoft.NET.Test.Sdk?

I tried to reproduce and cannot, I created a new project with the following CSPROJ,

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

  <PropertyGroup>
    <TargetFramework>netcoreapp1.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.0.0" />
    <PackageReference Include="NUnit" Version="3.7.1" />
    <PackageReference Include="NUnit3TestAdapter" Version="3.8.0" />
  </ItemGroup>

  <ItemGroup>
    <Service Include="{82a7f48d-3b50-4b1e-b82e-3ada8210c358}" />
  </ItemGroup>

</Project>

From the command line in the project directory, I run dotnet test,

C:\src\Spikes\CoreTests\CoreTests [master +1 ~1 -1 !]
λ dotnet test

My mistake, I switched the above from netcoreapp1.1 to netcoreapp1.0 and get the error you mentioned.

I'm not sure why this is working in the test solution, we will need to look into it.

Workaround for now is to switch to netcoreapp1.1 for now.

[rprouse]

It looks like targeting netcoreapp1.0 causes a reference to System.Runtime.InteropServices.RuntimeInformation version 4.0.0 to get pulled in. A second workaround is to add System.Runtime.InteropServices.RuntimeInformation` version 4.3.0 as a dependency.

We could add this as a NuGet dependency to fix.

@rprouse, can you review and approve #418?
