In .NET there is only one thread that does UI work, this is how you
access it irrespective of what thread makes the call. I use this for
event patterns often. The key is "SendOrPostCallback" which determines
if you are running on the UI thread.
I use this code often and it works under Mono. I think the behavior is
very different but the end result is what I am looking for.
protected SynchronizationContext _uiContext;
_uiContext = WindowsFormsSynchronizationContext.Current;
// * Interact with controls here
