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 this method directly, as shown in the Example section.

Forms authentication requires that the user specify their credentials through login controls provided by your application. You can retrieve the credentials and pass them to the Membership::ValidateUser method. You can also pass in empty strings or nullptr to use a credentials provider. For more information, see How to: Implement User Login with Client Application Services.

The following example code demonstrates how to use this method to validate the user by using an IClientFormsAuthenticationCredentialsProvider implementation. This example requires that you to configure your application to use a credentials provider. For more information, see How to: Configure Client Application Services.
