Not compatible with VSCode?

[VFerguson-haikurange]

I followed the directions found here:
https://docs.microsoft.com/en-us/dotnet/core/tutorials/testing-library-with-visual-studio-code?pivots=dotnet-6-0

Does not seem to work. I'm getting an error:
error CS0234: The type or namespace name 'VisualStudio' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)

I found others with this issue, but no solution.

Which version of TestFx are you using?
