if you declare a method as static it means whenever you will create the instance of the class the same copy of that method will be shared among all instances, and actually the last updated value of the method. Also, note that within a static method all properties must be static only otherwise you will receive an error. A static method is called by the class name (.) method name. open your RouteConfig.cs, under App_Start folder, here you will find that the RegisterRoute() method is declared as static, similarly Open BundleConfig.Cs file, here you will find that RegisterBundle() method is declared as Static because these are the method which loads the route and bundles in MVC app, so same copy of the updated method must be shared in the application. Hope this helped.

static methods are called using classname like classname.Delete(pass id);, non-static methods are called using class object like classObject.Delete(pass id);

There are two types of classes: Instance or Static. Instance - which is used by creating an object of the class with a new keyword. Static - will be used with the class name as it is shared in memory so you cannot have two different references for a static class (application for other static objects as well like, method, fields, etc). The best way to use static methods is to create helper methods.
