Do Windows 8 Store apps have a MessageBox equivalent?

Question

Do Windows 8 Store apps have something like a MessageBox?

I need something like a popup window to show the user e.g. when a input is wrong or a error happened. Is there something already in the API or do I have to make my own?

Answer 1

Modern UI guidelines sugest inline error messages for input. However, if you still want a MessageBox, you can have it in the MessageDialog.

 MessageDialog dlg = new MessageDialog("Message"); await dlg.ShowAsync();

Answer 2

You're looking for the MessageDialog class
