Visual Studio 2017 does not detect unit tests

Question

I run .NET Framework 4.6.1to create a library of test classes, where I build tests MSTest( Microsoft.VisualStudio.TestTools.UnitTesting). I can do tests fine by going to the folder containing the test project and running it dotnet test.

However, VS does not detect tests in the text explorer. I updated every single NuGet package to the latest, as recommended in some answer to this problem:

I also tried both Test -> Test Settings -> Default Processor Architecture -> x86and x64.

I always get the following error:

[1/10/2018 5:01:03 PM Warning] The test run will use the DLL (s) created for Framework Framework45 and the X86 platform. The following dlls will not be part of the run:
