Quality and reliability improvements

Note In addition to the following quality and reliability improvements, this update includes all previously released security, quality, and reliability improvements.

CLR

  • Very rarely, an instance of ReaderWriterLock may crash when releasing a lock. A new configuration variable is introduced to enable opting in to the fix. Set the environment variable COMPlus_ReaderWriterLock_UseFixedIdGeneration to 1 when you start the application to fix the issue.

WMI

  • Code was changed to make the setting of the permissions event-driven so that it could support changes in the option values.
