UWP messagebox mvvm

Question

I know there where many questions regarding how to open a MessageBox in UWP, but how do I open a MessageBox in MVVM?

After the User clicks A <Button> it fires a Command Command="{Binding FireComand}" in my VM it is handled like usual. In my case it adds an object to an ObservableCollection.

But I want my Users to get Feedback, that their Action worked/or not.

Is there an easy way to show a simple MessageBox "Done!" surrounded by a black Rectangle which closes after 2 sec?

EDIT: What I want is something like this

I thank you for the link - but the link does not answer my question for MVVM - I will edit my Question. — Daniel Maurer, May 22 '17 at 08:28
I have to correct myself. Toast is not what I am looking for! — Daniel Maurer, May 22 '17 at 10:43

You can dismiss a MessageDialog by cancelling the task created when calling its ShowAsync method, take a look at Programmatically dismiss a MessageDialog

Regarding MVVM, I abstracted dialogs into a service that I use in my ViewModels, take a look at https://github.com/igorkulman/Kulman.UWP/blob/master/Kulman.UWP/Services/DialogService.cs

Thank you! I will take a look in there. So DispatcherTimer dt = new DispatcherTimer(); dt.Interval = TimeSpan.FromSeconds(5); dt.Tick += dt_Tick; dt.Start(); } -> This Gets the Countdown, but how do I Close it from my VM? Sorry to bother you so much. – Daniel Maurer May 23 '17 at 08:43
Another question: How do I implement your Code? – Daniel Maurer May 23 '17 at 21:08
