The Test Runner runs fine without coverage, but "Run all, with coverage" shows errors. See messages from Output window below.
- The Test project is configured for .NET Framework 4.7
- The nuget packages MSTest.TestFramework v1.4.0 and MSTest.TestAdapter v1.4.0 are loaded
Apparently the assembly Microsoft.VisualStudio.TestPlatform.Core, Version=14.0.0.0 is missing.
My output directories (Debug and Release) list:
Microsoft.VisualStudio.TestPlatform.TestFramework.Extensions.dll
Microsoft.VisualStudio.TestPlatform.MSTest.TestAdapter.dll
Microsoft.VisualStudio.TestPlatform.MSTestAdapter.PlatformServices.dll
Microsoft.VisualStudio.TestPlatform.MSTestAdapter.PlatformServices.Interface.dll
Microsoft.VisualStudio.TestPlatform.TestFramework.dll
the one with .Core is missing.

Hi Olivier,
Thank you for pointing out the problem.
This is a known issue. The Test Runner API in Visual Studio 2019 has been changed and we planned to support the Code Coverage feature in our future releases.
We will inform you when this feature is implemented.
Hi Andrew,
Thank you for answering my issue promptly. Fortunately I have still VS 2017 installed.
I'm glad that you can use a workaround. We will try to support this functionality as quickly as possible.
