Console Application Related problem??

Aravind,

Its not a problem. it usually the rule in .net, that any project solution will have only one main method. If you have more than one main() method then it will pop up an error.

The main method is considered as the entry point of a C# console application or windows application. When you run the application, main is the first method that is invoked.
