Cannot update Silverlight UI from asynchronous method completed callback?

Degorolls is right in suggesting the TPL, your code would look like below (except without the comments)(Also, exceptions MUST be handled in the TPL, so that might make it not worth it, but I don't think it should). The first methods would remain the same, and yes in event-based async programming thread-safety is taken care of (ie: you always return to the same thread you called out from) I also noticed that the text output is all doing = instead of +=, but that is probably more of a problem of typing into overflow So, test1 and test2 will print out at the same time, however everything being spit out from the TPL code should print as it comes in. UI code should not be doing anything that requires too much time, though...only updating the UI.

So, do think of this as a point to refactor? Let me know if this helps or if I missed what you were looking for.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
