Property Value

BaseCompatibilityPreferences.HandleDispatcherRequestProcessingFailureOptions

A value that defines how the dispatcher reacts to failures.

Remarks

The Windows Presentation Foundation dispatcher reacts to failures that it encounters when requesting processing by setting a timer or posting messages to itself. If these operations fail because the underlying operating system resource is exhausted, the dispatcher becomes unresponsive. Typically, this failure is caused by an application posting messages faster than the dispatcher can handle them or by starving the dispatcher's message pump. To aid in diagnosing the cause of the dispatcher's unresponsiveness, you can control how the dispatcher responds to these failures by setting this property.

This property value can be changed at any time. If it is changed from multiple threads, the value is that set by the last writer ("last writer wins" behavior).
