Need Debugging and Testing instructions for contributors

I was able to run the tests in a terminal, but they don't show up in the VS Test Explorer, so I don't know how to debug them or to run a particular test. Can we make them discoverable by the VS Test Explorer? Maybe adding a .runsettings file would do it?

I installed the Expecto.VisualStudio.TestAdapter nuget package in the FsAutoComplete.Tests.Lsp project, but that did not reveal any tests in the VS Test Explorer.

I was also able to run all the tests by setting the FsAutoComplete.Tests.Lsp project as the startup project in VS Solution Explorer. But again, how do I tell it to run a particular test, not all of them?

Also, how does one debug FsAutoComplete? I ran it in the debugger and got a blank console window, but I don't know what to do with it. Entering F# code in that window did not do anything. I want to know how to hit a breakpoint when FsAutoComplete offers suggestions for an undefined symbol, for instance.

Thanks!
