Asynchronous HttpHandlers and WriteAsync

Question

I've been experimenting with some code code on Ayende Rahien's blog here which demonstrates using asynchronous HttpHandlers to improve the number of requests that can be processed concurrently.

Unfortunately I can get even the basic example to work. I'm getting the following error:

'System.IO.TextWriter' does not contain a definition for 'WriteAsync' and no extension method 'WriteAsync' accepting a first argument of type 'System.IO.TextWriter' could be found (are you missing a using directive or an assembly reference?)

for the line.

return context.Response.Output.WriteAsync("Hello World!");

I would imagine the method is an extension method added in net4 as part of the Parallel Extensions however for the life of me I can find the correct namespace.

Wouls any of you hardcore csharpers please shed the light.
