# .NET

> An open-source platform for building apps and cloud services

.NET is a free, open-source development platform for building applications and services. Developers use it for web backends, desktop software, mobile apps, cloud services, and other workloads, with shared libraries and tools across projects. It runs on Windows, Linux, and macOS, while specific application frameworks determine which devices and operating systems an app can target.

The platform provides APIs for common tasks such as working with collections, files, and network connections, and NuGet supplies additional packages. Developers can write C# using Visual Studio, Visual Studio Code, or the .NET command line, then connect builds and deployment to automated workflows. Teams can start with a small service or application and reuse familiar language features, libraries, and development practices as their needs expand.
