Comment Feed for Channel 9 - Language Support for Asynchronous Programming http://ch9files.blob.core.windows.net/ch9/01ff/f9ddc4c6-0383-4cc9-820e-b75a866f01ff/LangNEXT2012MadsTogersenAsync_220.jpg Channel 9 - Language Support for Asynchronous Programming Asynchronous programming is what the doctor usually orders for unresponsive client apps and for services with thread-scaling issues. This usually means a bleak departure from the imperative programming constructs we know and love into a spaghetti hell of callbacks and signups. C# and VB are putting an end to that, reinstating all your tried-and-true control structures on top of a future-based model of asynchrony. en Sun, 26 May 2013 03:11:24 GMT Sun, 26 May 2013 03:11:24 GMT Rev9 Re: Language Support for Asynchronous Programming I'm glad to see so many questions about async\await.  Hopefully a similar pattern will show up in other languages... hint, hint, C++ Smiley  Keep up the amazing work!!!

It may need conversion from IAsyncOperation<> to a Concurrency::task<> and then you can use Concurrency::task<>::get() to comfortably achieve the same thing as await.

auto classificationOp = runClassification(result->docText, result->lang);
task<Platform::String^>classificationTask(classificationOp);
Platform::String^ classification = classificationTask.get();

It took a while for that video to go up so I was completely unaware that Herb was already thinking about await as a C++ language extension or I would not have mentioned it again.  Thanks all language guys at Lang.Next, I've been very impressed.
