The [OperationContract] Attribute

Methods that you wish to be used within the WCF framework must be attributed with the

[OperationContract] attribute, which may also be configured with various named properties.

Using the properties shown in Table 25-7, you are able to declare that a given method is intended

to be one-way in nature, supports asynchronous invocation, requires encrypted message data,

and so forth (again, many of these values may be ignored based on your binding selection).

Table 25-7.
