Why we don't include Main() in namespace definition? If we use Main() in namespace then will that cause any error?

Why would you want to include main() in namespace declaration? What do you understand Namespace to mean?

A namespace contains similar type of classes as its members.
I am new to c# programming. Just for practice I created a new namespace and when I complied it I got entry point error I believe it was because of Main() and then this question occured to me.
Please explain.

In Windows applications and console apps, Main() is reserved as the entry point. That is where all startup point for your entire application.
