In the last vscode extension when you launch "execute and debug", the application is not compiled any more... then not found and not launched
If you have an old build, it launches it.... and you can loose 1 hour to understand why you don't see your changes...
If you delete the launch.json conf file. if will build again, but the name of the build is not the right one, so it won't launch.
To summarize, it's buggy, not tested.
SDK 4.1.1 is also full of bugs.
I'm bored to raise bugs...
