Hi All,

I know Thread.Sleep(number) is looked down upon as it locks the UI thread however reading a C# threading guide it uses Thread.Sleep(0); to give control to another thread. In some of past code there was annoying waits for things that was caused by the Threading were freed up via a Thread.Sleep(100) will Thread.Sleep(0); free up things with out a wait while the form does nothing!
Opions please!

is the same thing for Thread.SpinWait() I can't seem to find anything on it other than MSDN, from I can gather from a cursory read is it holds the thread like Thread.Sleep but not. Too much coding not enough coffee!!

You better do asynchronous calls where the endcall invokes a delegate that brings data / image / etc to the gui thread.
With asynchronity the GUI thread doesn't lock and the processing goes on. It gives better responsiveness to the system. You can create an abort call because buttons keep working....
