Remarks

WMIWorker is an implementation of the abstract ThreadWorker class, which performs work in a background thread allowing your foreground GUI to continue interacting with a user. Results are returned via a callback routine that is invoked when you poll for completed items.

See the remarks for ThreadManager for a comprehensive discussion of how to wire up and use ThreadWorkers.

Since CleanCode 0.9.07.
