Apps that are vulnerable to this issue perform work involving weak events or data binding after the Application.Run() function returns values.

• 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 the .NET Framework's 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, the .NET Framework will support dates that include 元.
