In ASP.NET MVC, we're required to use the suffix "Controller" for all controllers. This seems unnecessarily restrictive - is there a technical reason for it?
I'm mostly just curious, but can see situations where more flexible naming rules could improve code organization. Couldn't the discovery of possible controller classes be easily made using reflection to search for Controller derived classes? Or require that controller classes be marked with a ControllerAttribute?

In ASP.NET MVC, every controller class name must end with a word "Controller". For example, the home page controller name must be HomeController , and for the student page, it must be the StudentController . Also, every controller class must be located in the Controller folder of the MVC folder structure.
A controller is responsible for controlling the way that a user interacts with an MVC application. A controller contains the flow control logic for an ASP.NET MVC application. A controller determines what response to send back to a user when a user makes a browser request.
Step 1 − Create an MVC Empty Application and then right-click on the Controller folder in your MVC application. Step 2 − Select the menu option Add → Controller. After selection, the Add Controller dialog is displayed. Name the Controller as DemoController.
ASP MVC requires that all controllers implement IController interface. A controller doesn't need to derive from Controller or ControllerBase class. You can find an example of a custom controller implementing the IController interface in Adam Freeman's book.
The MVC community is heavily influenced by Ruby on Rails, which values "convention over configuration". By just naming things consistently, the application can run with zero configuration.

One of the benefits of this convention is that it's common to have a URL segment, controller, and a model class all have the same name.
URL: /product/ Controller: Product : Controller Model: Product
This would cause a naming conflict. So we made a convention to have controller names suffixed with "Controller" to avoid this conflict. However, you can override this behavior via our extensibility APIs.
