Silverlight 4 Data and Services Cookbook

Controlling a user's access to a service and service methods

In the previous recipe, we've learned how to track a user's identity. However, most applications that need a user's identity need it to do something with it, for example, restricting access to a certain service or a service method so that only an authenticated user can access it. This will make sure that our service can't be freely used by anyone. Only the users we allow in will be able to use it. In this recipe, you'll learn how to restrict access to a service or service method to authenticated users only.
