Microsoft announced earlier this year that it would end support for the Microsoft .Net Framework 4, 4.5 and 4.5.1 on January 12, 2016. End of support means that these .Net versions won’t receive security updates, technical support or hotfixes anymore.

The discontinuation of support won’t affect the following versions of the framework: 3.5, 4.5.2, 4.6 and 4.6.1.

Unlike previously released versions of the .Net Framework, these supported versions are defined as components instead of independent products by Microsoft. Components are supported for the lifecycle of the operating system they are available for which means that the listed .Net versions that are still supported by Microsoft after January 12, 2016 are supported for as long as the underlying version of Windows is supported.

Supported .Net versions running on a system with Windows Vista will be supported until April 11, 2017 for instance, while the same versions are supported until October 14, 2025 on systems running Windows 10.

System administrators and end users need to ensure that a supported version of the .Net Framework is installed on devices they manage or use. In most cases, this means updating the .Net Framework 4.x to version 4.5.2, 4.6 or 4.6.1.

Determining the .Net Framework version

End users can run the installer on their system to update the framework to the selected version. All available versions will be supported by Microsoft until the operating system reaches its end of support.
