.NET Framework system requirements

The tables in this article provide the hardware, operating system, and software requirements for the following .NET Framework versions:

  • .NET Framework 4.8 and its point release (4.8.1).
  • .NET Framework 4.7 and its point releases (4.7.1 and 4.7.2).

For information on .NET Framework versions earlier than .NET Framework 4.7, see .NET Framework versions and dependencies.

Development environments that enable you to develop apps for .NET Framework have a separate set of requirements.

Important

All .NET Framework versions since .NET Framework 4 are in-place updates, so only a single 4.x version can be present on a system. In addition, particular versions of .NET Framework are preinstalled on some versions of the Windows operating system. This means that:

  • If there's a later 4.x version installed on the machine already, you can't install a previous 4.x version.
  • If the OS comes preinstalled with a particular .NET Framework version, you can't install a previous 4.x version on the same machine.
  • If you install a later version, you don't have to first uninstall the previous version.

For download information and links, see Install the .NET Framework for developers.

For information on the support lifecycle of .NET Framework versions, see Microsoft Support Lifecycle.
