Don't know how that happened! Yes the quote should of course read:
/"*InvokeOnMainThread* will suspend the execution of your thread, and
wait for the delegate to be executed on the main thread. When that
completes, the thread resumes execution."/
Seems this is the solution to the OP's question? Mojo can you confirm?
Thanks,

Hey,
You misquoted the site. "InvokeOnMainThread" blocks execution until
the delegate is invoked. *Begin*InvokeOnMainThread does not.

Wouldn't plain 'InvokeOnMainThread' do what you are looking for?
From the Wiki at: http://wiki.ios.xamarin.com/HowTo/Threading
/"BeginInvokeOnMainThread will suspend the execution of your
thread, and wait for the delegate to be executed on the main
thread. When that completes, the thread resumes execution."

I would opt for Task and ContinueWith(). It's an awesome way of
dealing with such situations.
All locking, WaitHandles or Sleep calls can block the UI thread
on iPhone and cause very weird behavior or lockups.

You really can't do it without manually waiting for it.
What you can do is:
object obj = new object ();
BeginInvokeOnMainThread (delegate {
//Do something
lock (obj) { Monitor.Notify (obj); }
});
Thread.Sleep (2000);
lock (obk) { Monitor.Wait (obj); }
Ideally we would provide wrappers for common idioms of the .NET
plataform like making the
function return an IAsyncResult or Task object.

Hi,
In this code...
ThreadPool.QueueUserWorkItem (delegate {
BeginInvokeOnMainThread (delegate {
// Do something
});
Thread.Sleep(2000);
// Check something
});
... how can I make sure the "// Do something" is completely
done before
"//Check something"?
In other words, how can I check when BeginInvokeOnMainThread
is done and
then do some stuff still in the ThreadPool.QueueUserWorkItem?
Thanks!
