WCF WebHttp Services in .NET 4
Part of the official .Net 4.0 framework release.
WCF WebHttp Services is the flavor of WCF that is most appropriate for developers who need complete control over the URI, format, and protocol when building non-SOAP HTTP services— services that may or may not subscribe to RESTful architectural constraints.

WCF WebApi
This project focuses on allowing developers to expose their apis for programmatic access over HTTP by browsers and devices.
Essentially this is a continuation of work done on the WCF Rest starter kit, and could be considered as a preview of wcf http services for .net 5.0?
WCF REST Starter Kit (depreciated)
The new WCF Web Api’s recently announced at PDC replace the REST Starter Kit and provide significant enhancements including better access to HTTP, more flexibility with representations and support for jQuery. Please go to http://wcf.codeplex.com/ for more information.

RestSharp
http://restsharp.org/ A client only api for consuming rest services
RestSharp is a simple, open source REST client for .NET designed primarily for consuming third-party HTTP APIs. RestSharp is NOT:
- A REST server framework
- A SOAP client
