Quality and Reliability

This release contains the following quality and reliability improvements.

  • Addresses an issue with a crash on COM interop to properly return the hresult for the Out of Memory Exception
  • Addresses an issue in some 32 bit apps where, in certain scenarios, the JIT might omit a function call
  • Improved support for cleaning up private temporary certificate keys

  • Improved spell checking so words like "etc." and "e.g." will no longer be identified as spelling errors when spell-checking is enabled in WPF TextBox or RichTextBox
  • Addresses an issue with a null-reference crash in automation code, arising from re-entrancy when reconnection to a remote desktop
