Where the methods of Global.asax come from?

Question

When I add Global.asax to the page, five methods (Application_Start,Session_Start,...) are added to the page automatically. But where they come from ? I looked at the application class and its interfaces but I couldnt find them at all.

Thanks in advance,

These methods don't come from anywhere, they exist only on your class. However, the ASP.NET runtime looks for methods in your class with these names and calls them at appropriate times in the application/page lifecycle.
