Applies to: .NET Framework

Improvements and fixes

This update includes quality improvements. No new operating system features are being introduced in this update. Key changes include:

• Addresses an issue in which the System.Security.Cryptography.Algorithms reference was not correctly loaded on .NET Framework 4.7.1 after the July 10, 2018 and August 14, 2018 patches.
• Addresses a crash due to TaskCanceledException that can occur during shutdown of some WPF apps. Apps that continue to do work involving weak events or data binding after Application.Run() returns are known to be vulnerable to this crash.
• Addresses a race condition in temporary files and some antivirus scanners that causes .NET Framework applications to stop working. The error message is, "The process cannot access the file <name of temp file>".
• Updates support for the formatting of Japanese dates for the first year in the eras. When the format pattern is “y年”, the year format will use the symbol 元 and not use year number 1. Additionally, we will support dates that include 元.
• Updates Venezuela currency information. This will affect the culture of “es-VE” as follows:

• Currency symbol is changed to “Bs.S”
• English currency name is changed to “Bolívar Soberano”
• Native currency name is changed to “bolívar soberano”
• International currency code is changed to “VES”

• Addressed an issue with KB4096417 where we switched to CLR-implemented write-watch for pages. The GC will no longer call VirtualAlloc when running under workstation GC mode.
• Addressed a System.AccessViolationException due to accessing disposed X509Certificate2 instance in a rare race condition to defer the service certificate cleanup to GC. The impacted scenario is WCF NetTcp bindings using reliable sessions with certificate authentication.
• Provides an AppContext flag for making the default value of TransparentNetworkIPResolution false in SqlClient connection strings.
• Addressed an issue on some .NET Remoting scenarios, when using TransactionScopeAsyncFlowOption.Enabled, it was possible to have Transaction.Current reset to null after a remoting call. This occurred when the remoting call did not leave the caller’s AppDomain (with 4.7.2).
