Summary

This update for the .NET Framework 4.6 and 4.6.1 on Window 8.1 and Windows Server 2012 R2 includes cumulative improvements in reliability in the .NET Framework 4.6 and 4.6.1. We recommend that you apply this quality rollup as part of your regular maintenance routines. Before you install this update, see the "Prerequisites" and "Restart requirement" sections.

Quality and reliability improvements

  • Windows Presentation Foundation (WPF)

    Customers loading WPF applications that target SxS versions of the .NET Framework in a single process may experience crashes or unexpected behavior on stylus or touch enabled devices. This is sometimes seen when the Visual Studio Tools for Office add-in that is loaded is written in WPF.This error occurs because of a conflict between different versions of PenIMC.dll. This update addresses and fixes this issue.

    Note This update also contains cumulative updates that were released previously starting from October 11, 2016.
