The .NET platform (pronounced as "dot net"; formerly named .NET Core) is a free and open-source, managed computer software framework for Windows, Linux, and macOS operating systems. It is a cross-platform successor to the .NET Framework. The project is mainly developed by Microsoft employees by way of the .NET Foundation and is today released under an MIT License.

New versions of the .NET platform are released annually, typically in November. The most recent version of .NET is .NET 10, released in November 2025, which is a long-term support (LTS) version, and is scheduled to receive updates until November 2028.
