CodeMash 2013 Microsoft Data Stack
1 like436 views
The document discusses Microsoft's data stack, including REST, OData, and various client and server technologies. It provides information on understanding and exploring different data formats, clients, and service options. Specific topics covered include REST vs OData, WCF Data Services, the Entity Framework object modeling layer, and examples of consuming OData services from Netflix, TechEd 2010, and Twitter.
![ Implementation of IDataService
Expose functions & methods with [WebGet]
public class PocoData : DataService< PresenterData >
{
// This method is called only once to initialize service-wide policies.
public static void InitializeService(DataServiceConfiguration config)
{
config.SetEntitySetAccessRule("*", EntitySetRights.AllRead);
config.SetServiceOperationAccessRule("*", ServiceOperationRights.All);
config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2;
}
}

{
return new List<string>() { "Hello World", "Whee!" };
