@spottedmahn and @ekennedy6334 Check your solution files and see if they have a “GlobalSection(NestedProjects) = preSolution” section. If they do:

Close Visual Studio.
Make a copy of your solution file for safe keeping.
Completely delete that section in your solution file.

Once I did that, “Live Unit Testing” started working again. I’m not sure what that section of the solution file does, but deleting it doesn’t appear to have negative side effects for me.

Just posting in case anybody has this issue recently like me. I had the exact same issue on Visual Studio 2019 Target: .NET 4.7.1. Absolutely no fixes on any thread, testing framework, or anything would fix the issue including restoring NuGets, Repairing VS, and adding adapter references. My solution was to reset all values in Test > Live Unit Testing > Options to EXACTLY match the following from How to configure and use Live Unit Testing
