'Declaration <AspNetCompatibilityRequirementsAttribute(RequirementsMode := AspNetCompatibilityRequirementsMode.Allowed)> _ <ServiceBehaviorAttribute(InstanceContextMode := InstanceContextMode.PerCall)> _ Public Class DataService(Of T) _ Implements IRequestHandler
Type that defines the data service.
Thetype exposes the following members.
|AttachHost||Attaches the data service host to the data service identified by the parameter host.|
|CreateDataSource||Creates a data source of the template class that will be used by the data service.|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|HandleException||Called when an exception is raised while processing a request.|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|OnStartProcessingRequest||Called before processing each request. For batch requests, it is called one time for the top batch request and one time for each operation in the batch.|
|ProcessRequest||Processes an HTTP request.|
|ProcessRequestForMessage||Processes an HTTP request.|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
The class does the basic integration of all components of the server system. A new data service that uses system defaults for authorization and caching is created by defining a class that derives from the class and by referencing a compatible data model.
The type of the must expose at least one property that returns an entity set that is an IQueryable(Of T) collection of entity types. This class must also implement the IUpdatable interface to enable updates to be made to entity resources.
