WCF Data Services

WCF Data Services replaces the ADO.Net Data Services; WCF Data Services helps us to expose data in a standardized format from datasource using Open Data Protocol (OData) which can be consumed by any application/service by placing a REST format HTTP Request.

WCF Data Services are available as part of Visual Studio 2010. WCF Data Services can be created on Data Models which are created using the ADO.Net Entity Data Model; they also support data models that are based on common language runtime (CLR) objects that return an instance of the IQueryable interface. This helps us to create data services for data which is placed in lists, arrays, and collections in the .NET Framework. To enable create, update, and delete operations for these data structures, we must implement the IUpdatable interface.
