Universal Apps MessageBox: "The name 'MessageBox' does not exist in the current context"

Question

I want to use MessageBox for showing download errors in my WP8.1 app. I added: ``` using System.Windows; ``` but when I type: ``` MessageBox.Show(""); ``` I get error: ``` "The name 'MessageBox' does not exist in the current context" ``` In Object Browser I found that such class should exist and in "Project->Add reference... ->Assemblies->Framework" is shown that all assemblies are referenced. Do I miss something? Or is there another way how to show something like messagebox?

Accepted Answer

For Universal Apps, the new APIs require you to use `await MessageDialog().ShowAsync()` (in Windows.UI.Popups) to bring it into line with Win 8.1.

```
var dialog = new MessageDialog("Your message here");
await dialog.ShowAsync();
```
