Provided tasks from extension are not recognized when told to launch in a preLaunchTask from the "workspace" configuration file. However, if a launch.json is provided in the .vscode/ folder, with the "preLaunchTask": "someTaskExtensionProvides" then it works.

There seems to be no documentation anywhere that describes the difference here or what I need to do, to expose my provided task to be recognized from the workspace configuration file.
