Introduction

This November 2018 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 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

  • Fixes an issue that occurs when many processes that use the workstation garbage collection (GC) are running on the same system. In this situation, you may experience high CPU usage. After you apply this fix, the GC no longer calls VirtualAlloc when it runs under workstation GC mode.

SqlClient2

  • Provides an AppContext flag for making the default value of TransparentNetworkIPResolution false in SqlClient connection strings.

WCF3

  • Fixes a System.AccessViolationException that occurs when accessing a disposed X509Certificate2 instance in a rare race condition. The fix defers the service certificate cleanup to GC. The affected scenario is WCF NetTcp bindings using reliable sessions with certificate authentication. Customer can opt-in to the fix by adding the follow AppSetting to the configuration file. Without setting AppSetting to true, existing services won’t be affected by this code change.

    <appSettings>
      <add key="wcf:deferSslStreamServerCertificateCleanup" value="true"/>
    </appSettings>


1 Common Language Runtime (CLR)
2 .NET Framework Data Provider for SQL Server (SqlClient)
3  Windows Communication Foundation (WCF)
