Issue Description

Trying to execute a simple test from VSTest Explorer doesn't work.

Steps to Reproduce

[SabotageAndi]

Could you create a small project to reproduce your issue? Thanks!

@SabotageAndi - https://github.com/venkatrao-rgare/specflow-vs2019, at this stage i am not sure if this is an issue with specflow or vs2019 or some setup in my machine. I am fairly new to specflow and visual studio. Please try this project and let me know if this works for you.

@venkatrao-rgare I could reproduce your issue. Your project is fine.
For me, the problem was, that the test explorer was set to x86, but I don't have .NET Core for x86 installed. I only have x64 installed.
You can see this in the logfile. There is an entry like Executing test executor at 'C:\Program Files (x86)\dotnet\dotnet.exe' 'exec ' .....

After changing to x64, I was able to execute the tests successfully.

@SabotageAndi - Thanks so much it worked for me too :)
