Modifying WPF controls from the background thread

To be able to change anything from another thread on the WPF window, you can use the Dispatcher.

 

Define function inside Your CodeBehind or ModeView

private void InvokeOnWindow(Action action)
{
    System.Windows.Application.Current.Dispatcher.Invoke(DispatcherPriority.Background, action);
}

using:

InvokeOnWindow(()=>{SomeProperty="Value"});
