If in the background thread you're not accessing any shared resources you may not need to do any synchronization. You can use BeginInvoke with a delegate to call a function and put it on a background thread to do background processing. Some people will use a callback to set off a function that say accesses excel, I usually don't do that. I'll call that function at the end of the method that does the background task. In that called function I'll use if (Invoke.Required) to switch back to the ui thread if necessary or not if the function doesn't touch the ui and then that function can do whatever it needs to do.

I want to do some work on a background thread. At the end of the background processing I need to access Excel to insert some data into a worksheet. Do I need to do any synchronisation as in a windows forms application? If I need to, how should I do it? I haven't found an ISynchronizeInvoke implementation. Or does the runtime do the synchronisation? The Excel classes are COM interop.
