Earlier this week, we released the November 2020 Security and Quality Rollup Updates for .NET Framework.

Security

The November Security and Quality Rollup Update does not contain any new security fixes. See October 2020 Security and Quality Rollup for the latest security updates.

Quality and Reliability

This release contains the following quality and reliability improvements.

SQL
  • Addressed an issue in System.Data.SqlClient where querying string columns would fail if the database had a Kazakh collation.
WPF2
  • Addressed a regression from a previous update, arising when two HostVisual elements disconnect at the same time.
  • Addressed a crash and/or hang when typing into a TextBox in a WPF app, when the OS feature “use text cursor indicator” is enabled.

2 Windows Presentation Foundation (WPF)
