.NET Framework June 2019 Preview of Quality Rollup

Quote:
Today, we are releasing the June 2019 Preview of Quality Rollup.

Quality and Reliability

This release contains the following quality and reliability improvements.

WPF1
  • Addresses an issue in which applications that target .NET Framework 4.7 and later, or that set Switch.System.Windows.Controls.Grid.StarDefinitionsCanExceedAvailableSpace to “false,” experienced hangs because of the manner in which the algorithm allocated space to grid columns or rows whose width or height include an asterisk (*). [806901]
  • Improves the memory allocation and cleanup scheduling behavior of the weak-event pattern. To opt-in to these improvements, set AppContext switches to “true”: Switch.MS.Internal.EnableWeakEventMemoryImprovements and Switch.MS.Internal.EnableCleanupSchedulingImprovements. [763101]
  • Addresses an InvalidOperationException that can arise during weak-event cleanup, if called re-entrantly while a weak-event delivery is in progress. [812614, 822169]
ASP.NET
  • Addresses InvalidOperationException errors in System.Web.Hosting.RecycleLimitMonitor+RecycleLimitMonitorSingleton.AlertProxyMonitors. Worker processes for ASP.Net 4.7 and later are vulnerable to unexpected crashes because of this exception if the worker process consumes close to its configured Private Bytes recycling limit and application domains are being created or recycled (perhaps because of configuration file changes, or the presence of more than one application per worker process). [776516, 856170]
Workflow
  • Addresses an issue in which it was possible for a Workflow Service to get into a looping situation if an unhandled exception occurs during Cancel processing. To break this cycle, the Web.config file for the workflow service can have the following AppSetting specified that will cause the workflow service instance to terminate, instead of abort, if an unhandled exception occurs during Cancel processing. [721251, 866801]
<appSettings>
<add key=”microsoft:WorkflowServices:TerminateOnUnhandledExceptionDuringCancel” value=”true”/>
</appSettings>
