Remarks

In applications with Middle Tier Security, call this method on the server and client sides to register your custom permission requests and custom logon parameters. You do not need to use this method when you use standard logon parameters and do not have custom permission requests. Do not use this method to register business classes.

The AddKnownType method throws an InvalidOperationException if the WebApiDataServerHelper.GetKnownTypes method was already called internally. If you receive this exception, call this method earlier, before the data server and/or client application are initialized.
