DataService<T> DataService<T> DataService<T> DataService<T> Class

Definition

The main entry point for developing an ADO.NET Data Service.

generic <typename T>
public ref class DataService : System::Data::Services::IRequestHandler
[System.ServiceModel.Activation.AspNetCompatibilityRequirements(RequirementsMode=System.ServiceModel.Activation.AspNetCompatibilityRequirementsMode.Allowed)]
[System.ServiceModel.ServiceBehavior(InstanceContextMode=System.ServiceModel.InstanceContextMode.PerCall)]
public class DataService<T> : System.Data.Services.IRequestHandler
type DataService<'T> = class
    interface IRequestHandler
Public Class DataService(Of T)
Implements IRequestHandler

Type Parameters

T

Type that defines the data service.

Remarks

The DataService<T> 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 DataService<T> class and by referencing a compatible data model.

The type of the DataService<T> must expose at least one property that returns an entity set that is an IQueryable<T> collection of entity types. This class must also implement the IUpdatable interface to enable updates to be made to entity resources.

Constructors
