Description

If I choose 'start debugging (run extension) in the newly generated extension, extension host does not actually start and the whole thing is in some "hang state". In a while "Waiting for preLaunchTask 'build'..." message appears.

Appeared that default build task depends on two watch tasks, and they, eventually never finish.

Quick googling revealed a problem, but the solution from that post did not help.

Changing preLaunchTask to a non-watch task (i.e.: npm: compile) helps, but increases startup time.

Also, it was mentioned earlier: https://github.com/microsoft/vscode-generator-code/issues/311

Research direction

Inspect the generated extension's default build task, preLaunchTask, and the two watch tasks described in the report. Compare them with the non-watch npm: compile task and determine how the generated debugging configuration should avoid waiting indefinitely. Done means a newly generated TypeScript extension starts debugging without the reported hang.
