Can u help me plzzz. Its really very urgent.

Code of WCF Service

[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]
   public class Service1 : IService1
       //bool boolValue = true;
       //string stringValue = "Hello ";
       public string Greet(string words)
           return GreetInternal(words);
       public string Greet2(string words)
           return GreetInternal(words);
       string GreetInternal(string words)
           MySessionState state = (MySessionState)HttpContext.Current.Session["MySessionState"];
           if (state == null) {
               state = new MySessionState();
               HttpContext.Current.Session["MySessionState"] = state;
           int counter = state.Touch();
           return string.Format("[Session '{0}'] You said: {1} (counter: {2})", HttpContext.Current.Session.SessionID, words, counter);

   class MySessionState
       int counter;
       public MySessionState() { }
       public int Counter { get { return this.counter; } }
       public int Touch() { return Interlocked.Increment(ref this.counter); }

Note to OP: Please do not use text speak. Also, it may be urgent for you, but not for us. So try avoiding that while posting.

There are three things to consider while sharing sessions:

1. aspNetCompatibilityEnabled = true
2.[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
3. allowCookies = true

I think that's enough hint for you to proceed.

BTW, I personally do not like kind of design. I would have used following approach:

Your session object should made a data contract or a message contract and then passed on to service. That IMHO is cleaner and decoupled way of doing things.
