Niner since 2012
No VisualStudio 11 support for us Windows 8 developers yet... :/
Speaking about, Achievements for WinJS would be nice, too!
Achievements for creating a native component, employing new controls like SemanticZoom and others come to mind
@AceHack: it is possible to wait for the result of an asynchronous operation in C++ using PPL tasks.
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);
Platform::String^ classification = classificationTask.get();
