Applies to: .NET Framework 4.6.2


The November 2017 Update for Windows 10 version 1507 fixes an issue in the .NET Framework 4.6.2. We recommend that you apply this update as part of your regular maintenance routines. Before you install this update, see the "Prerequisites" and "Restart requirement" sections.

Issues fixed

Windows Presentation Framework (WPF)

  • Mixed mode WPF applications that handle first chance exceptions see a System.Argument.Null exception, as TargetFrameworkName is NULL in mixed-mode applications.
  • A WPF application may not always load resources from a resource dictionary assembly if two or more versions of the same assembly are loaded.
  • A WPF application that's running on a touch/stylus-enabled system that creates new windows on separate dispatcher threads will experience a single handle leak per dispatcher thread. In some scenarios, this could lead to handle exhaustion over time.
  • 4048718 WPF crashes after the October 2017 Security and Monthly Quality Rollup is applied on Windows 10 version 1507 that has Microsoft .NET Framework 4.6.2 installed.
