VSTS: Test runner finds no tests

Question

I have a .net 4.6 MVC app and a standard test project which was generated by Visual Studio with a few controller tests. These all discover and pass in VS test runner but I'm trying to get VSTS to execute these tests now and fail the build if any tests fail. However, no tests are discovered and I get a lot of 'Input string not in the correct format' error. I haven't changed anything in the tests and all I did was add the test task to my build phase. Here is the full test output:

Has anyone come across this before? I kinda assumed that the standard Visual Studio test task in VSTS would run a standard test project generated by VS2017 by default! Thanks

My SLN is a simple file->new app and has two projects:

Answer 1

The template provided in VSTS for the Visual Studio Test defaults the Test Assemblies parameter as:

**\*test*.dll
!**\*TestAdapter.dll
!**\obj\**

Unfortunately, other assemblies may sneak into the search path. Try adjusting the Test Assemblies to the following:

**\*test*.dll
!**\*TestAdapter*.dll       <--- changed
!**\*VisualStudio*.dll      <--- added
!**\obj\**
