The WebInvokeAttribute attribute is applied to an operation in addition to the OperationContractAttribute and associates the operation with a UriTemplate as well as an underlying transport verb that represents an invocation (for example, HTTP POST, PUT, or DELETE). The WebInvokeAttribute attribute is a passive operation behavior (the IOperationBehavior methods do nothing) that adds metadata to the operation description. Applying the WebInvokeAttribute attribute to an operation has no effect unless a behavior that looks for this metadata in the operation description (such as WebHttpBehavior) is added to the behavior collection. The WebInvokeAttribute determines what HTTP method that an operation responds to. By default, all methods that have the WebInvokeAttribute applied respond to POST requests. The Method property allows you to specify a different HTTP method. If you want an operation to respond to GET, use the WebGetAttribute instead.

The following example shows how to use the WebInvokeAttribute attribute.

NoteNote:

Because the Method property is not specified in the following code, all operations are mapped to the HTTP POST method.
