Issues that are fixed in this update
SQL Server (SQL)
- Fixes an issue in which the .NET Framework API SqlConnection.ConnectionString property is used to set a null or empty connection string. In this situation, a Null Reference Exception (NRE) occurs when you use the API together with .NET Framework 4.7.2. [611802, System.Data.dll, Bug]
- Fixes an issue in which you connect to Azure SQL DB and MultipleActiveResultSets=true is used in the connection string together with System.Data.SqlClient.SqlConnection. In this situation, the async query operations cause a bad TDS protocol request stream to be sent from the client. This causes the Async Query APIs to fail. [620109, System.Data.dll , Bug]
Windows Presentation Framework (WPF)
- Adds an AppContext switch that opts out of some work that was done during AppDomain or process shutdown. This issue can reduce (but not eliminate) the possibility of a crash in applications that make unwarranted assumptions about the timing of the finalizer thread. [593963, WindowsBase.dll, Bug]
- Fixes a crash in WPF that occurs when you multiple characters are replaced by a single character (in a different language than the original text) by using IMEPad. [605996, PresentationFramework.dll, Bug]
- Combo box grouped items now report children correctly through UIAutomation. [605922, PresentationFramework.dll, Bug]
This version of .NET Framework runs side-by-side with .NET Framework 3.5 SP1 and earlier versions. However, it performs an in-place update for .NET Framework 4, 4.5, 4.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7, and 4.7.1.
- Applications that rely on .NET Framework to initialize a COM component and that run with restricted permissions may fail to start or run correctly, and return "access denied," "class not registered," or "internal failure occurred for unknown reasons" errors.
