Description of Preview of Quality Rollup for .NET Framework 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1, and 4.7.2 for Windows 7 SP1 and Server 2008 R2 SP1 and for .NET Framework 4.6 for Server 2008 SP2 (KB4502558)

Applies to:

Microsoft .NET Framework 4.6, Microsoft .NET Framework 4.6.1, Microsoft .NET Framework 4.6.2, Microsoft .NET Framework 4.7, Microsoft .NET Framework 4.7.1, Microsoft .NET Framework 4.7.2

The June 2019 update for Windows Server 2008 SP2 includes cumulative reliability improvements in .NET 4.6. We recommend that you apply this update as part of your regular maintenance routines. Before you install this update, see the Prerequisites and Restart requirement sections.

Important

  • All updates for .NET Framework 4.6 for Windows Server 2008 Service Pack 2 (SP2) require that the d3dcompiler_47.dll update is installed. We recommend that you install the included d3dcompiler_47.dll update before you apply this update. For more information about the d3dcompiler_47.dll, see KB 4019990.

  • If you install a language pack after you install this update, you must reinstall this update. Therefore, we recommend that you install any language packs that you need before you install this update. For more information, see Add language packs to Windows.

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 (*).

  • 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.

  • Addresses an InvalidOperationException that can arise during weak-event cleanup, if called re-entrantly while a weak-event delivery is in progress.

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).

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:

<appSettings>

<add key="microsoft:WorkflowServices:TerminateOnUnhandledExceptionDuringCancel" value="true"/>

</appSettings>
