You can use client application services to validate users by using forms authentication. To validate users, you will typically call the static Membership::ValidateUser method, which internally calls the ClientFormsAuthenticationMembershipProvider::ValidateUser method. Alternatively, you can call the ClientFormsAuthenticationMembershipProvider::ValidateUser method directly. You can call this overload to access an authentication service at the location specified by the serviceUri parameter. Using this overload is an alternative to setting the ServiceUri property and calling the ValidateUser(String^, String^) overload.

The following example code demonstrates how to use this method to validate the user through an authentication service at a specified location. The user credentials are retrieved from login controls in your application code. This example requires a TextBox control named usernameTextBox and a TextBox control named passwordTextBox.
