Hi Sukesh, If we want to create Singleton Pattern then class should be Sealed Right? In you are example its not sealed. Can you please explain me on this. And correct me if my understanding is wrong.

Basically my question is we can do these things without this private constructor, singleton. then what is the use?

sukesh i m not clear. can u explain me in detail. bcz to save settings across all user we can create normal class who has static property. if i want to share per user then i will store simple class object in session, and for per request no need to do anything just create simple object

@Sandeep - As "objPriSingleton" is a static object, hence CLR will ensure that it is created on only one thread, making it thread safe. Im not sure if the ASP.net implementation using "HttpContext.Current...." is thread safe. If you are creating an object through a method then you should use locking. Below is a good explanation of singelton pattern creation with object lock: http://msdn.microsoft.com/en-us/library/ff650316.aspx
