.NET Framework is a software framework developed by Microsoft that runs primarily on Microsoft Windows. It includes a large class library named Framework Class Library (FCL) and provides language interoperability (each language can use code written in other languages) across several programming languages.
With .NET you can target any application type running on any platform. Developers can reuse skills and code across all of them in a familiar environment. That means developers can build apps faster, with less cost.
From mobile applications running on iOS, Android, and Windows, to Enterprise server applications running on Windows Server and Linux, or high-scale microservices running in the cloud, .NET provides a solution for you.
