The December 10, 2019 update for Windows 7 SP1 and Windows Server 2008 R2 SP1 and Windows Server 2008 SP2 includes cumulative reliability improvements in .NET 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, and 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 4.6 for Windows Server 2008 Service Pack 2 (SP2) 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 now emits 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 are also issued with SameSite = 'Lax' instead of the previous default of 'None', though these values can be overridden in web.config. Applications that use these cookies across sites – or with iframes – may see a loss of functionality that will require configuration updates to remedy.
For more information, refer to: https:⁠//docs.microsoft.com/en-us/aspnet/samesite/system-web-samesite.
