      • On Main() and Command Line Arguments (C# Programming Guide) , there is a statement: It (the Main method) is declared inside a class or struct. It must be static and it should not be public. (In the example above it receives the default access of private.) In contrast, the main method of Java MUST be public. Could anybody explain why the Main method of C# should not be public Thanks.
