Ordinarily the
Application.Current.RootVisual.Dispatcher property is used to retrieve the
System.Windows.Threading.Dispatcher for an application. Of course this won't work if performed before the
RootVisual has been assigned. To get the Dispatcher for an application before the
RootVisual has been assigned, use the
System.Windows.Deployment.Current.Dispatcher property.
C#:
var dispatcher = Deployment.Current.Dispatcher;
VB.NET:
Dim dispatcher As Dispatcher = Deployment.Current.Dispatcher
