Aaron at Pluralsight is all over this release of a starter kit for accessing REST APIs in an easier way. Essentially, it introduces a new class – HttpClient – that contains a bunch of methods suitable for talking to REST APIs.

You can download the preview here and in the process of looking at this info, I also found a dedicated set of resources on REST with WCF on MSDN (whaddyaknow?) 

Have a look at this great video from Aaron that covers building a Twitter client (Console!) using the kit in 3 mins. Or take a look at the code here.
