Known issues

For IT administrators

After installing this update, some .NET Framework 3.5 apps may experience issues or fail to open. Affected applications include the use of some optional components in the .NET Framework 3.5, such as Windows Communication Foundation (WCF) and Windows Workflow (WWF) components.

Advanced users or IT administrators can do this programmatically by using an elevated command prompt (run as administrator) and running the following command:

dism /online /enable-feature /featurename:netfx3 /all

dism /online /enable-feature /featurename:WCF-HTTP-Activation

dism /online /enable-feature /featurename:WCF-NonHTTP-Activation

This update will be delivered to users through Windows Update. The user does not need to take any action as the download and installation are automatic.
