The November 19, 2019 update for Windows 7 SP1 and Server 2008 R2 SP1 and Server 2008 includes cumulative reliability improvements in .NET 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, 4.7.2. 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.

Important

  • Starting in August, 2019, updates to .NET Framework 4.6 and above, for Windows Server 2008 SP2, Windows Server 2008 R2 SP1, and Windows 7SP1, require SHA-2 Code signing support. Please make sure that you have all the latest Windows Updates before applying this update to avoid installation issues. For more detailed information about SHA-2 code signing support updates, please see KB 4474419.

  • All updates for .NET Framework 4.7.2, 4.7.1, 4.7, 4.6.2, 4.6.1, and 4.6 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, see KB 4019990.

  • 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

ASP.NET

ASP.NET will now emit a SameSite cookie header when HttpCookie.SameSite value is "None" to accommodate upcoming changes to SameSite cookie handling in Chrome. As part of this change, FormsAuth and SessionState cookies will also be issued with SameSite = 'Lax' instead of the previous default of 'None', though these values can be overridden in web.config.

CLR2

Addresses an issue where System.Windows.Forms.ComboBox control with ImeMode set to ImeMode.NoControl on CHS with Pinyin keyboard retained input mode of the parent container control instead of switching to disabled IME when navigating using mouse clicks and when focus moves from a control with disabled IME to this ComboBox control.

SQL

Addresses an issue with SqlClient Bid traces where information wasn't being printed due to incorrectly formatted strings.

WCF1

Addresses a race condition when using WCF TCP Port Sharing where a client which disconnects part way through the session establishment handshake can result in the WCF Service no longer being able to accept new connections.

When an IIS worker process has many WCF TCP web services using TCP Port Sharing and the worker process crashes while under high CPU load, a race condition during TCP Port sharing reinitialization can result in some endpoints not being able to accept client connections. Added an AppSetting to enable retrying initialization when this happens.
