About .NET

.NET is a unified resource for many developer needs. Whether you are building a web app, a mobile game, or an AI-driven service, you can do it with .NET - and target multiple platforms at the same time. With first-class support for C#, F# and Visual Basic, plus frameworks like ASP.NET for the web and .NET MAUI for mobile and desktop, it provides a powerful and flexible toolkit.

One of .NET's strengths is that it is fully open source and community-driven. Microsoft leads the project, but thousands of developers around the world contribute libraries, tools and SDKs. You’ll find everything from official SDKs to niche open source projects on GitHub. And if you get stuck, community resources like Stack Overflow are full of .NET questions and answers - you’re rarely alone.

In short: if you want to build modern, scalable, cross-platform applications on a solid foundation with a large ecosystem, .NET is an excellent choice.

.NET is often used together with
