How do I popup in message in UWP?

Question

In my Windows 8.1 app I used MessageBox.Show() to popup a message. That is gone in UWP. How can I show a message?

Yup, indeed something like that, the new method is to use the MessageDialog class. You have to create an object of that type. You can also add buttons. It's a bit more complex I think. But you can also use some shortcuts here. To just show a message, use this:

await new MessageDialog("Your message here", "Title of the message dialog").ShowAsync();
To show an simple Yes/No message, you can do it like this:

MessageDialog dialog = new MessageDialog("Yes or no?");
dialog.Commands.Add(new UICommand("Yes", null));
dialog.Commands.Add(new UICommand("No", null));
dialog.DefaultCommandIndex = 0;
dialog.CancelCommandIndex = 1;
var cmd = await dialog.ShowAsync();

if (cmd.Label == "Yes")
{
    // do something
}
