WCF Advantages over Web Service
WCF supports more of the WS-* standards than Web Services. You can’t really do streaming or support atomic transactions etc in Web Services. WCF supports multiple binding’s HTTP, WSHTTP, TCP, MSMQ etc. ASP.NET Web Services has only http.
Web Services have no instance management, i.e. you cannot have a singleton web service, or a session-full web service. You can maintain state of web services but we all know how painful that is.
WCF while very similar to Web Services also incorporates many of the features of Remoting and .NET Enterprise Services (COM+ Services Components).
It is flexible and extensible like Remoting only more so.
It is compatible like Web Services only more so.
It is feature rich like Enterprise Services only more so
1) WCF can maintain transaction like COM+ Does
2) It can maintain state
3) It can control concurrency
4) It can be hosted on IIS, WAS, Self hosting, Windows services
5) It has AJAX Integration and JSON (JavaScript object notation) support

Dear Srinu,
I have seen your write-up four days ago and writing this since I felt very happy on seeing your Blog in Google while I was surfing in a non-affirmation that I get our village’s name, but luckicly enough, I have seen it and felt and for some moments, there are no words. I came to know that you are doing in the present situation when I visited our native last year, your brother told me. I would like to share my ideas with you provided you continue mails and I would like to know how to make an entry in our village’s google site. Because I want to provide some information about village since I was a dude in our cute village.
Wish you all the best and may God take you to even higher positions.
With warm wishes,

Hi Srinivas Sir,
Thax for ur information
Hi Sir,
Nice to see your profile. I am Suma Chandra working for Amsol.
Can u pls provide me the code or any idea about disabling back after user log out
To disable the back button, you have to clear previous history from the browser.
http://www.developerfusion.com/thread/51491/how-to-disable-back-button-of-the-browser-after-logout/ link might help you.
you can use javascript method ie:history.back() on body load event
you can use these binding with different security levels.
