.NET framework is a Microsoft technology which allows one to port programs developed in Microsoft technologies to multiple platforms. It also allows the developers to integrate with other tools and technologies making it faster to develop compelling applications.

The .NET framework includes:

  • Common Language Runtime that provides an abstraction layer over the Operating System
  • Base Class Libraries for low level programming tasks
  • Development framework for reusable solutions for larger programming tasks.
