Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. .NET Framework versions and dependencies
In this articleEach version of .NET Framework contains the common language runtime (CLR), the base class libraries, and other managed libraries. This article describes the key features of .NET Framework by version, provides information about the underlying CLR versions and associated development environments, and identifies the versions that are installed by the Windows operating system (OS). Each new version of .NET Framework adds new features but retains features from previous versions. Note .NET Framework is serviced monthly with security and reliability bug fixes. .NET Framework will continue to be included with Windows, with no plans to remove it. You don't need to migrate your .NET Framework apps, but for new development, use .NET 6 or later. The CLR is identified by its own version number. The .NET Framework version number is incremented at each release, but the CLR version is not always incremented. For example, .NET Framework 4, 4.5, and later releases include CLR 4, but .NET Framework 2.0, 3.0, and 3.5 include CLR 2.0. (There was no version 3 of the CLR.) Tip
Version informationThe tables that follow summarize .NET Framework version history and correlate each version with Visual Studio, Windows, and Windows Server. Visual Studio supports multi-targeting, so you're not limited to the version of .NET Framework that's listed.

Remarks for version 4.5 and later.NET Framework 4.5 is an in-place update that replaces .NET Framework 4 on your computer, and similarly, .NET Framework 4.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, 4.7.2, and 4.8 are in-place updates to .NET Framework 4.5. In-place update means that they use the same runtime version, but the assembly versions are updated and include new types and members. After you install one of these updates, your .NET Framework 4, .NET Framework 4.5, .NET Framework 4.6, or .NET Framework 4.7 apps should continue to run without requiring recompilation. However, the reverse is not true. We do not recommend running apps that target a later version of .NET Framework on an earlier version. For example, we do not recommend that you run an app the targets .NET Framework 4.6 on .NET Framework 4.5. The following guidelines apply:
Some changes in .NET Framework may require changes to your app code; see Application Compatibility before you run your existing apps with .NET Framework 4.5 or later versions. For more information about installing the current version, see Install the .NET Framework for developers. For information about support for the .NET Framework, see .NET Framework official support policy on the .NET website. Remarks for older versions.NET Framework versions 2.0, 3.0, and 3.5 are built with the same version of the CLR (CLR 2.0). These versions represent successive layers of a single installation. Each version is built incrementally on top of the earlier versions. It's not possible to run versions 2.0, 3.0, and 3.5 side by side on a computer. When you install version 3.5, you get the 2.0 and 3.0 layers automatically, and apps that were built for versions 2.0, 3.0, and 3.5 can all run on version 3.5. However, .NET Framework 4 ends this layering approach, and it and later releases (.NET Framework 4.5, 4.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, 4.7.2, and 4.8) also represent successive layers of a single installation. Starting with .NET Framework 4, you can use in-process, side by side hosting to run multiple versions of the CLR in a single process. For more information, see Assemblies and Side-by-Side Execution. In addition, if your app targets version 2.0, 3.0, or 3.5, your users may be required to enable .NET Framework 3.5 on a Windows 8, Windows 8.1, or Windows 10 computer before they can run your app. For more information, see Install the .NET Framework 3.5 on Windows 11, Windows 10, Windows 8.1, and Windows 8. Important Starting with Visual Studio 2022, Visual Studio no longer includes .NET Framework components for .NET Framework 4.0 - 4.5.1 because these versions are no longer supported. Visual Studio 2022 and later versions can't build apps that target .NET Framework 4.0 through .NET Framework 4.5.1. To continue building these apps, you can use Visual Studio 2019 or an earlier version. Next steps
