I was getting a similar issue and noticed somehow an app.config file had been added to my test project. Removing this config file fixed it for me.

Answer 3

I solved this issue by installing NUnit3TestAdapter NuGet into my project (https://www.nuget.org/packages/NUnit3TestAdapter/).

dotnet add package NUnit3TestAdapter --version 3.17.0

My .csproj file

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

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="16.7.1" />
    <PackageReference Include="NUnit" Version="3.12.0" />
    <PackageReference Include="NUnit3TestAdapter" Version="3.17.0" />
    <PackageReference Include="RestSharp" Version="106.11.7" />
  </ItemGroup>

</Project>

Answer 4

You can try to change your default processor architecture in your Test Setting from X86 to X64. In my case this was the problem.

This happens if the platform target of your project under test is set to x64.

Answer 5

In Visual Studio 2017 I just uninstall and reinstall NUnitTestAdapter or install new package like NUnitTestAdapter.WithFramework package and problem gone.

Answer 6

In my case Reinstalling Nunit3 Adapter, Deleting temp folders, Changing architecture and nothing worked. Its because of the Daemon Resharper caused the problem.

Add or Remove Programs> Find Resharper > Repair > Install again > Restart VS 

That resolves the issues.
