At PDC10, you were introduced to Async (new async and await language keywords), a new language feature in C# and VB.NET. At the same time, the Rx team shipped the latest version of their software, which adds the following capabilities to the library:
- Support for the new C# await keyword (Observable.GetAwaiter)
- ToTask and ToTaskLast operators
- IAsyncEnumerable interface and all standard query operators for this interface.
Enjoy. Learn. Code.
