Doctor Who, thanks for the question! Yes, I’m working in VS 2019. But you can unload a project in any VS. When you do it, in the Solution Explorer you will see just one line saying “MatchingGame (unloaded)”. When you right-click on, the option “Edit MatchingGame.csproj” becomes available (it was not there when the project was loaded). That is only for old style project files. For the new SDK-style projects the option “Edit MatchingGame.csproj” is always available on the right-click on the project in Solution Explorer so there is no need to unload a project.
