MORE INFORMATION

There are currently five released versions of the .NET Framework:
  • The .NET Framework 4
  • The .NET Framework 3.5

    Service Pack 1 (SP1) is the latest service pack.
  • The .NET Framework 3.0

    Service Pack 2 (SP2) is the latest service pack.
  • The .NET Framework 2.0

    Service Pack 2 (SP2) is the latest service pack.
  • The .NET Framework 1.1
    Service Pack 1 (SP1) is the latest service pack.
  • The .NET Framework 1.0
    Service Pack 3 (SP3) is the latest service pack.
You may have several versions of the .NET Framework installed on your computer. Each version of the .NET Framework can co-exist with the other versions on the computer.

Note Most of the time, you can use the latest version of the .NET Framework to run applications that were created by using earlier versions of the .NET Framework. The .NET Framework 4 does not automatically roll forward older applications. Older applications require the Framework they target to be installed unless the developer provides a configuration file to redirect the application to run on .NET Framework 4.

Note Before you install a release version of the .NET Framework, you must remove any beta versions on which the release version is based. If you do not do this, the installation of the release version of the .NET Framework will fail. You can uninstall beta versions of the .NET Framework by using the Add or Remove Programs tool in Control Panel. This is a good first step to try if the installation of the .NET Framework fails from the Microsoft Update Web site and you need to troubleshoot the issue.

The following list includes some of the benefits of having the .NET Framework installed:
  • Easier installation of commercial applications: Many commercial applications from Microsoft and from third parties rely on the .NET Framework to support their core functionality. If you have the .NET Framework installed, these applications are easier to install. Some applications that depend on the .NET Framework for support include the following:
    • Microsoft Security Essentials
    • Intuit QuickBooks
    • HP Image Zone
    • Streamload
    • PayPal
    • Grouper
  • Easier updates: After the .NET Framework is installed, it is updated automatically by the Microsoft Update service. If you receive Automatic Updates through Control Panel, any versions of the .NET Framework that are installed on the computer will always be up to date with the latest service packs.
