Download .NET Framework
.NET Framework is a Windows-only version of .NET for building client and server applications.
We recommend that all new product development uses .NET 8 or later. These newer .NET versions are cross-platform, support more application types, and deliver high performance.
You should only download .NET Framework if one of the following is true:
- An application you're building requires .NET Framework.
- An application you're using requires .NET Framework.
