The ASP.NET MVC is a discontinued web application framework developed by Microsoft, which implements the model–view–controller MVC pattern. It is open-source software, apart from the ASP.NET Web Forms component which is proprietary.
ASP.NET Core has since been released, which unified ASP.NET, ASP.NET MVC, ASP.NET Web API, and ASP.NET Web Pages a platform using only Razor pages. MVC 6 was abandoned due to Core and is not expected to be released. Core is currently planned to merge into “.NET 5”.
Based on ASP.NET, ASP.NET MVC allows software developers to build a web application as a composition of three roles: Model, View and Controller. The MVC model defines web applications with 3 logic layers:
A model represents the state of a particular aspect of the application. A controller handles interactions and updates the model to reflect a change in state of the application, and then passes information to the view. A view accepts necessary information from the controller and renders a user interface to display that information.
In April 2009, the ASP.NET MVC source code was released under the Microsoft Public License MS-PL.
"ASP.NET MVC framework is a lightweight, highly testable presentation framework that is integrated with existing ASP.NET features. Some of these integrated features are master pages and membership-based authentication. The MVC framework is defined in the System.Web.Mvc assembly."

In March 2012, Scott Guthrie announced on his blog that Microsoft had released part of its web stack including ASP.NET MVC, Razor and Web API under an open source license Apache License 2.0.
Guthrie wrote that "Doing so will enable a more open development model where everyone in the community will be able to engage and provide feedback on code checkins, bug-fixes, new feature development, and build and test the products on a daily basis using the most up-to-date version of the source code and tests."
The source code now resides on CodePlex. ASP.NET Web Forms was not included in this initiative for various reasons.
