Migrating to 2012.. Didn't think it will be so much work with all the lambdas I have!

Anyway, I think I got a hang of async/await stuff and all is well except for parallel coroutines.

Documentation: http://drc.ideablade.com/devforce-2012/bin/view/Documentation/program-asynchronously

suggests I use "await Task.WhenAll(..)"

Silverlight doesn't have .WhenAll, only .WaitAll and it is not awaitable. When I try to do Task.WaitAll - I get lock issue..

Is there something I'm missing here?

In Silverlight you can await TaskEx.WhenAll.
 
The Compatibility library also includes Coroutines if you find converting all your code to DF2012 too much work for now.

Thanks for quick reply!

Yeah, I already started. Big task but I'd rather do it right. It is also learning async/await pattern in addition to migrating..

There's also Cocktail's TaskFns class, which has platform independent implementations of WhenAll etc. in case you ever intend to share source code between platforms.
