Version:
.NET Framework 3.5 and 4.7.2

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”
