Re: Mono, Windows Forms, and Headless operation

Again, I agree with the separation of business logic from the GUI.  In
fact, on mono, I never want to see the GUI.  It¹s due to the fact that my
parallelism relies on multiple concurrent BackgroundWorkers.  I¹m
restricted to .net 2.0 , nothing later.  So I don¹t have the TPL
available.  I have BackgroundWorkers, Threads, and Threadpool.  As I
understand it, Threadpools don¹t have a way to know when they are finished
(at least, not directly).  Perhaps I misunderstand.  BackgroundWorkers are
simple, and are performing their function perfectly on Mono, so long as X
is there.  The only option left is directly using Threads.

So to be clear, the only reason I wanted Windows Forms on Mono is to use
BackgroundWorker because it¹s simple and it works.
