Question

Is it possible to define more then one function in AJAX Enabled WCF Service ?
For instance:

[OperationContract]
    public string GreetUser(string uname)
    {
        return "Hello " + uname;
    }
 public string DeleteUser(string uname)
    {
        return "Hello " + uname;
    }

Answer 1

Just add an [OperationContract] above DeleteUser.

Note that you cannot overload a function/method using WCF Services. The names have to be unique. You can change the OperationContract Name attribute to fix overloaded functions/methods.
