Remarks

Resource-level change authorization and validation is implemented by methods annotated on the ChangeInterceptorAttribute. WCF Data Services provides the infrastructure required for service developers to write per-entity change processing rules and validation.

Entity-level access control and validation can be enforced through query interceptors. For more information, see QueryInterceptorAttribute.

Examples

For more information, see the example in the QueryInterceptorAttribute topic.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
