Remarks

The WebGetAttribute attribute is applied to an operation in addition to the OperationContractAttribute and associates the operation with a UriTemplate as well as the HTTP protocol Get verb. The association with HTTP Get verb means that the operation is used to retrieve information. The WebGetAttribute attribute is a passive operation behavior (the IOperationBehavior methods do nothing) that adds metadata to the operation description. Applying the WebGetAttribute attribute to an operation has no effect unless a behavior that is looking for this metadata in the operation description (such as WebHttpBehavior) is added to the behavior collection.

Operations with the WebGetAttribute attribute applied should be logical retrieval operations. The HTTP GET method is associated with all operations marked with the WebGetAttribute attribute.

Examples

The following example shows how to use the WebGetAttribute attribute.
