We've been extensively testing my code change and so far it works great in production, average CPU usage went down from 90% to 4% on exchange operations.

I also looking into async a while ago. I did take a a bit of a different approache. I decided to create a new project targeting .NET 4.5 to leave the existing code in place and use partials to extend the classes with Async methods (not everything has support nor has it been properly tested). I cleaned/updated the code some days ago to feed as input for a discussion on async for EWS-Managed and whether it is desired to have it included (e.g. the framework is not threadsafe to begin with). The branch can be found at async.

@WGroenestein good approach - I honestly don't mind which one is chosen, as long as we can use async within EWS.

Any update on a merge for the async support ? or a pointer to an existing Async EWS Managed API somewhere else ?

Like @ticapix said is there any update on this? This is a necessity nowadays to have async methods.
Thanks

Oh, very nice! Did you base it on HttpClient?
