The Web Application Toolkit for REST services allows for ASP.NET and AJAX clients to call RESTful services, where as the WCF REST Starter kit allows you to create and consume RESTful services using WCF.

Nope. Both uses WCF.Web Application Toolkit for REST Services says "It exposes an API using REST services built with the Windows Communication Foundation that can consumed by client applications"WCF-REST Starter Kit is all about WCF.

Sorry, my bad. Hopefully the edited version is better.

Sorry, but no. Quoute: "This Web Application Toolkit shows how to easily add REST service interfaces for an existing Web application" Both can be used to create WCF Rest services.

This is the first time I have come across the Web Application Toolkit for REST services. After downloading it and sniffing around, it appears to be more of a sample application that shows you how to use the WCF REST capabilities that were released in .NET 3.5.

The WCF REST Starter kit built on top of the REST library in .net 3.5 to make it easier to produce REST services. In my opinion, WCF REST Starter kit Preview 2 has been completely replaced by the capabilities that are in .Net 4.0.

In summary the toolkit is a set of samples that show you how you can use WCF REST in .Net 3.5. WCF REST Starter kit was a set of experimental extensions that have been released in .Net 4.
