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(String, String) method. Alternatively, you can call the ClientFormsAuthenticationMembershipProvider::ValidateUser method directly. You can call this overload to pass in a rememberMe value in addition to the username and password values.

The following example code demonstrates how to use this method to validate the user by using login controls in your application code. This example requires a TextBox control named usernameTextBox, a TextBox control named passwordTextBox, and a CheckBox control named rememberMeCheckBox.
