Hello Gerald!

Thank you for contacting us.

Could you please check that the problem project has references to the following nuget packages required to run tests:

<PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.3.0" />
<PackageReference Include="xunit" Version="2.2.0" />
<PackageReference Include="xunit.runner.visualstudio" Version="2.2.0" />

Thank you.

Hi Angelina,

I've been stuck on the same problem for the past 3 days. I'm running Visual Studio 2017 (15.5.6), Resharper 2017.3.2 with Machine.Specifications.Runner.Resharper 2.1.2 extension. I made sure my project has the following includes:

However the tests are not being run. The error messages look exactly like the ones Gerald pasted. Can you please give me some help?

Thank you.

Hello Marco!

Thank you for contacting us.

Is the issue reproduced in some specific solution only or in newly created also?

Could you please provide the full list of package references?

Thank you.

Good morning Angelina,

I managed to fix this problem by installing .NET Core cross-platform development feature for my Visual Studio. Turned out it's a VS problem rather than Resharp's. Thanks a lot!
