To get it to work.

In your class

private SynchronizationContext synchronizationContext;

In the UI thread (main thread)

synchronizationContext = System.Threading.SynchronizationContext.Current;

In the worker thread

synchronizationContext.Post(    
   state => DoUpdateInUIThread((Abc)state),     
   abc);
