.NET is a general purpose development platform for any kind of app or workload, providing key capabilities for building high quality apps including automatic memory management and support for modern programming languages.
Productive, multi-purpose, type-safe, object-oriented, open source
C# and Visual Basic are programming languages designed for creating a variety of applications that run on the .NET Framework. These languages are powerful, type-safe, and object-oriented. They are built on the .NET Compiler Platform “Roslyn” which provides rich code analysis APIs and it’s all open source on GitHub.
F# is an open source, cross-platform, functional-first programming language that enables developers to tackle computing problems with simple, maintainable and robust code. F# is on GitHub, and many tools and libraries are available from the F# community.
Open, flexible tools you need to create and deploy modern web apps
Leverage your skills in C# and Visual Basic to take advantage of the power of Windows 10 to build the next generation of apps.
Windows 10 runs on a single, unified core across devices—mobile, desktop, Xbox, or elsewhere. Windows 10 apps you build with C# and Visual Basic run as fast as C++ with the .NET Native runtime.
The .NET framework and Visual Studio enable you to develop data-centric, modern line of business applications (LoB) for Windows. Create visually stunning user experiences with WPF or use WinForms productive WYSIWYG designers to incorporate UI, media, and complex business models. Rapidly develop enterprise-class line of business applications with a comprehensive set of features like controls, data binding, animation, styles, templates, and more.
.NET Core is a set of runtime, library and compiler components optimized for modern workloads that run on Windows, Mac OS X and Linux. It can be installed locally with your app with only the packages you need. .NET Core runtime, libraries and compiler are all open source on GitHub and are taking contributions.
