Sitefinity MVC Modes: Classic, Pure, and Hybrid
Sitefinity supports three MVC modes. We call them classic, pure and hybrid. The mode used depends on your development process as well as the functionality you want to implement.

For more information on the different modes, see the documentation: Three MVC Modes, as well as the following sections:
For additional information on which mode to chose for your implementation, see the article: Which mode should I use.
