DispatcherOperationCallback Delegate

.NET Framework 4.5

Represents a delegate to use for dispatcher operations.

Namespace: System.Windows.Threading
Assembly: WindowsBase (in WindowsBase.dll)

public delegate Object DispatcherOperationCallback(
	Object arg
)

Parameters

arg: Type: System.Object
An argument passed to the callback.

Return Value

Type: System.Object
The object returned by the callback.

Remarks

It is not necessary to use this delegate for dispatcher operations, but DispatcherOperationCallback and SendOrPostCallback use dynamic invoking.

Partial Trust applications do not support dynamic invoking, so you must use either DispatcherOperationCallback or SendOrPostCallback if the application is going to be running in Partial Trust.
