Gets or sets the object used to marshal the event handler calls that are issued as a result of a process exit event.

When the Exited event is handled by a visual Windows Forms component, such as a Button, accessing the component through the system thread pool might not work, or might result in an exception. Avoid this by setting to a Windows Forms component, which causes the methods handling the Exited event to be called on the same thread on which the component was created.
If the Process is used inside Visual Studio 2005 in a Windows Forms designer, is automatically set to the control that contains the Process. For example, if you place a Process on a designer for Form1 (which inherits from Form) the property of Process is set to the instance of Form1:
Me.process1.StartInfo.Domain = "" Me.process1.StartInfo.LoadUserProfile = False Me.process1.StartInfo.Password = Nothing Me.process1.StartInfo.StandardErrorEncoding = Nothing Me.process1.StartInfo.StandardOutputEncoding = Nothing Me.process1.StartInfo.UserName = "" Me.process1.SynchronizingObject = Me
Typically, this property is set when the component is placed inside a control or form, because those components are bound to a specific thread.
