)

The visual.

DispatcherOperation
The dispatcher operation to track the outcome of the call.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type Visual. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
Exceptions
ExceptionCondition
InvalidOperationExceptionThe dispatcher has already shut down.
Remarks
DispatcherObject may have an empty Dispatcher, e.g. for Freezable objects, thus calling DispatcherObject.Dispatcher.BeginInvoke is considered unsafe. However Visual objects always have a valid dispatcher, so calling Visual.BeginInvoke via this extension can be considered safe.
