Events

	Name	Description
	SafeDispatcherUnhandledException	Occurs when a thread exception is thrown and not caught during execution of a delegate by way of Invoke, BeginInvoke, or InvokeAsync.

Remarks

The SafeDispatcher class is a wrapper on the WPF Dispatcher class, and exposes a safe variant for the Invoke, BeginInvoke, and InvokeAsync methods of the Dispatcher class. These methods internally handle any exceptions raised by the delegates called by the methods, and can notify user about the error for handling.

Do not use the SafeDispatcher class directly in your code. It is exposed as a protected property on the DynamicsBaseHostedControl Class, and you should use this property on your custom hosted control instance that is derived from the DynamicsBaseHostedControl Class.

Thread Safety

Any public static ( Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
