I don’t use the Solution explorer but I also don’t think it has one.
I usually kickstart a fresh application with a SLN and a few projects in the dotnet CLI and VSCodium picks up the launch project automatically when I tell it to create a launch.json. For existing applications, if the .vscode folder already exists it will just pick it up or I can also just ask it to create a launch.json.
That workflow has been ingrained into me since there were no real C# utilities for VS Code when it first launched, so not much changed for me when going to VSCodium.
Thanks for documenting it for future people! Glad you got it to work.
