Description of the Security and Quality Rollup for .NET Framework 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, and 4.7.2 for Windows 7 SP1 and Server 2008 R2 SP1 and for .NET Framework 4.6 for Server 2008 SP2 (KB 4459942)

Notice

This update is included in the Security and Quality Rollup that's dated November 13, 2018. This update was previously released as part of the Preview of Quality Rollup on October 23, 2018.

Introduction

This update for Windows 7 Service Pack 1 (SP1) and Windows Server 2008 R2 SP1 includes cumulative reliability improvements in .NET Framework 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, and 4.7.2. Additionally, this update for Windows Server 2008 Service Pack 2 (SP2) includes cumulative reliability improvements in .NET Framework 4.6. 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.

Important

All updates for .NET Framework 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1 and 4.7.2 require that the d3dcompiler_47.dll update is installed. We recommend that you install the included d3dcompiler_47.dll update before you apply this update. For more information about the d3dcompiler_47.dll update, see KB 4019990 for Windows 7 SP1 and Windows Server 2008 R2 SP1. Or, see KB 4019478 for Windows Server 2008 SP2.
If you install a language pack after you install this update, you must reinstall this update. Therefore, we recommend that you install any language packs that you need before you install this update. For more information, see Add language packs to Windows.

Quality and reliability improvements

CLR¹	Updates Japanese dates that are formatted for the first year in an era and for which the format pattern uses “y年”. The format of the year together with the symbol "元" is supported instead of using year numeral 1. Also, formatting day numbers that include "元" is supported.
WF²	Fixes an issue in some .NET Framework remoting scenarios in which Transaction.Current resets to null after a remoting call if TransactionScopeAsyncFlowOption.Enabled is used. Sometimes this occurs because the remoting lease lifetime expires while the remoting call is outstanding (before .NET Framework 4.7.2). This also occurs if the remoting call does not leave the caller's application domain (AppDomain) (in .NET Framework 4.7.2). For the "lease lifetime expired" issue, a new AppSetting for the configuration file is introduced that enables you to specify the lease lifetime of the object that tracks Transaction.Current in the call context. You should set this lease lifetime value to the number of minutes of the longest expected remoting call. The AppSetting should resemble the following: <add key="Transactions:ContextKeyRemotingLeaseLifetimeInMinutes" value="5"/> Note The value specifies the lease lifetime for the object in minutes.
WinForms³	Fixes a performance regression issue that occurs when you create WinForms controls. This regression was introduced in .NET Framework 4.0 because calls were made to load the Common Control library (ComCtl32.dll).
WPF⁴	Fixes a race condition that involves temporary files and some antivirus scanners. This issue causes crashes and errors messages that resemble the following: The process cannot access the file temp_file_name. Fixes a crash that occurs because a TaskCanceledException can occur during shutdown of some WPF applications. Applications that continue to do work that involve weak event patterns or data binding after Application.Run() returns values are known to be vulnerable to this crash scenario.

¹ Common Language Runtime (CLR)
² Windows Workflow Foundation (WF)
³ Windows Forms (WinForms)
⁴ Windows Presentation Foundation (WPF)
