How to activate an existing View in Catel.MVVM?

How to activate an existing View in Catel? IUIVisualizerService.Show() always create a new View. I am currently using the following code in ViewModel, which is not nice since it is dependent on Window.

private void ShowSomethingExecute() {
  var uiVisualizerService =  this.GetDependencyResolver().Resolve<IUIVisualizerService>();
  var viewManager = this.GetServiceLocator().ResolveType<IViewManager>();

  var testView = viewManager.GetFirstOrDefaultInstance(typeof(TestView));
  if (testView == null) {
    uiVisualizerService.Show(new TestViewModel());
  } else {
    (testView as Window)?.Activate();
  }
}

There is no way to re-activate a window in the current version. But the good news is that everything is pluggable / replaceable in Catel so you can easily provide your own version that supports this feature.

Or you could create a PR and support this in Catel as well ;-)
