WCF DataService

WCF Data Services allow you to expose and work with data by using the Open Data Protocol (OData). Data is exposed over REST-based services to allow for standard HTTP GET and POST requests. The data can be accessed based on a URL and standard query string formats for accessing tables and filtering data. These formats allow access from any client that can receive XML or JSON message notations.
