Late last week we released the September 2018 Preview of Quality Rollup.
Quality and Reliability
This release contains the following quality and reliability improvements.
CLR
- Updated code to prevent errors regarding invalid date format when Japanese Era 4 is used with a future date [568291]
- Parsing Japanese dates having a year number exceeding the number of years in that date era will succeed instead of throwing errors [603100]
- When asynchronously reading a process output an IndexOutOfRangeException is thrown when less than a character’s worth of bytes is read at the beginning of a line [621951]
- Fix in the JIT compiler for a rare case of struct field assignments, described here: https://github.com/Microsoft/dotnet/issues/779 [641182]
- DateTime.Now and DateTime.Utc will now always be synchronized with the system time, DateTime and DateTimeOffset operations will continue to work as it used to work [645660]
- Spin-waits in several synchronization primitives were conditionally improved to perform better on Intel Skylake and more recent microarchitectures. To enable these improvements, set the new configuration variable COMPlus_Thread_NormalizeSpinWait to 1. [647729]
- Corrected JIT optimization which resulted in removal of interlocked Compare Exchange operation [653568]
WPF
- Under certain circumstances, WPF applications using the spell-checker that use custom dictionaries can throw unexpected excpetions and crash [622262]
Note: Additional information on these improvements is not available. The VSTS bug number provided with each improvement is a unique ID that you can give Microsoft Customer Support, include in StackOverflow commentsor use in web searches.
