Client application services provide simplified access to Microsoft Ajax login, roles, and profile services from Windows Forms and Windows Presentation Foundation (WPF) applications. You can use the Services page of the Project Designer to enable and configure client application services for your project.
With client application services, you can use a centralized server to authenticate users, determine each user's assigned role or roles, and store per-user application settings that you can share across the network. For more information, see Client Application Services.
To access the Services page, select a project node in Solution Explorer, and then click Properties on the Project menu. When the Project Designer appears, click the Services tab.
Client application services require the full version of the .NET Framework, and are not supported in the .NET Framework Client Profile. If the Enable client application services check box is disabled, verify that the Target framework is set to the .NET Framework 3.5 or later. To view the Target framework setting in C#, open the Project Designer and then click the Application page. To view the Target framework setting in Visual Basic, open the Project Designer, click the Compile page, and then click Advanced Compile Options.

If you leave this box blank, you must pass a valid user name and password to the Membership.ValidateUser method. You must specify the credentials provider as an assembly-qualified type name. For more information, see Type.AssemblyQualifiedName and Assembly Names. In its simplest form, an assembly-qualified type name looks similar to the following example: MyNamespace.MyLoginClass, MyAssembly
