.NET Framework Update KB4489192 (April 2, 2019)

On April 2, 2019, Microsoft released a cumulative security update KB4489192 for .NET Framework 3.5 and 4.7.2 for Windows 10, version 1809, and Windows Server 2019.

The list of improvements and fixes for the KB4489192 cumulative security update is pleasingly short:

• Addresses an issue in which the Framework throws an exception if the year in the parsed date is greater than or equal to the start year of the next era. Now, the framework will not throw such exception.
• Updates Japanese Era dates that are formatted for the first year in an era and for which the format pattern uses the "y年" characters. The format of the year together with the symbol "元" is supported instead of using year number 1. Also, formatting day numbers that include "元" is supported.
• Allows the output of Gannen characters in Japanese Era formatting of first year dates regardless of whether the format pattern includes single quotation marks around the "年" character.

So once again we are talking about patching the Japanese calendar. There are no known problems with this update. The update must be triggered in the settings page via > Settings > Update & Security > Windows Update, and select Check for updates.
