Problem description

Visual Studio 2022 hangs on Open Folder when Test Explorer is open.

It occurs when IVsSccFolderProviderBinder.SccBindingsChanged event is called from IVsSolutionEvents7.OnAfterOpenFolder method.

This repository contains a synthetic example for demonstration purposes, but the problem was originally reproduced on a real-world source control plug-in.

Steps to reproduce

1. Initial settings for Visual Studio Experimental Instance:
   • Tools -> Options... -> Environment.
     • On startup, open: Empty environment.
   • View -> Test Explorer.
     • Pin the window so that it appears the next time you start Visual Studio.
2. Download the project.
3. Open the solution in Visual Studio.
4. Debug -> Start Debugging (F5).
5. In the opened Visual Studio Experimental Instance:
   • Tools -> Options... -> Source Control.
     • Current source control plug-in: Test Source Control Provider.
   • File -> Open -> Folder....
   • Select any folder.
