I want to build a web chat by using Ajax. The chat message should be stored in an Application object, so every user can receive the chat messge through access the content of Application object.

So i want to use the Ajax.net Pro library, but i found there is something wrong while try to access the Application object in a method which is marked by [AjaxPro.AjaxMethod()] attribute.

Would you please give me some suggestion about how to access the Application object by using the Ajax.net Pro library?
