Codespace: dotnet process not terminating automatically

[Arlodotexe]

Problem

Labs is designed to be run in a GitHub Codespaces. That means when the user is able to select a Lab project from the "Run" dropdown, and upon running, build and view a sample in the browser.

However, there's a bug which prevents this from being done more than once without manually running killall dotnet or rebuilding the codespace.

Repro steps

1. Open Labs in a Codespace
2. Build and run a sample.
3. Either stop the build with the "Stop" button, or refresh the page.
4. Try to build and run again. You'll be met with an error like "address is in use".

@Arlodotexe could we just add a killall dotnet to the top of the commands run in the launch.config?

If the process is left running, how does that work for codespace going to idle or whatever after the tab is closed?

Actually we might able to add it as a prelaunch task to the existing run tasks.
