Thank you. I am not sure why I used static. It worked after removing.
what else do I need to take care when I have single service with multiple clients.( do I need to queue my request)

Mine requirement is stated here:

@ virusstorm : Thank you for the suggestion. I am just trying to learn WCF.

Here is my goal for today:
a. Single Service serving multiple clients.
b. Client will request for "Start Operation", Service will perform the operation and send the result back to the same client.

Let me know if I am not clear still..

Thank you Sergey.

I will keep you posted. I wanted to know if I am on right track.
