Description of Preview of Quality Rollup for .NET Framework 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, and 4.7.2 for Windows 8.1, RT 8.1 and Server 2012 R2 (KB 4342315)

Introduction

This August 2018 update for Windows 8.1, Windows RT 8.1, and Windows Server 2012 R2 includes cumulative reliability improvements in .NET Framework 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

All updates for Windows 8.1, Windows RT 8.1 and Windows Server 2012 R2 require that update KB 2919355 is installed. We recommend that you install update KB 2919355 on your Windows 8.1-based, Windows RT 8.1-based or Windows Server 2012 R2-based computer so that you receive updates in the future.
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.NET¹	Fixes an issue in which .NET Framework Data Provider for SQL Server (SqlClient) logon may hang indefinitely. This issue occurs when the .NET Framework Data Provider for SqlClient truncates a small millisecond time out value to zero when the Provider converts the timeout period to seconds.
CLR²	Fixes an issue that results in a System.InvalidProgramException exception for some very large XSLT transforms. This fix may also resolve this kind of issue for other very large methods.
SQL³	Fixes an issue in which .NET Framework Data Provider for SQL Server (SqlClient) logon may use an infinite time out because of truncating a small millisecond time out to zero when it converts to seconds.
WCF⁴	Fixes a race condition that exists in the AsyncResult that closes a WaitHandle before Set() is called. When this occurs, the process crashes and returns an ObjectDisposedException exception. Fixes an issue in which applications that use WCF to communicate with web services or applications through data contract serialization directly may experience some failures because the serialization process does not first deserialize the CultureAwareComparer object. You might receive the following exception, but other exception types are possible also: Exception type: System.Runtime.Serialization.SerializationException Message: 'EndElement' 'Comparer' from namespace '' is not expected. Expecting element '_compareInfo'.
WPF⁵	Fixes an issue that could cause a deadlock condition in multithreaded WPF applications that process large packages at the same time. This condition may occur when one file is closing, and the other file starts to consume larger amounts of memory. Fixes an issue in which WPF applications that use WindowChromeWorker may experience high CPU usage or may crash under certain conditions.

¹ Active Server Pages .NET (ASP.NET)² Common Language Runtime (CLR)³ SQL Server (SQL)⁴ Windows Communication Foundation (WCF)⁵ Windows Presentation Foundation (WPF)
