Login screen in Windows store app - MessageDialog

Question

I'm wondering, how to create login screen to looks like in picture below. It looks like MessageDialog, but I have no idea, how to achieve that kind of stuff. I was searching on net for this, but nothing usefull for total beginner as I am.

I know how to create MessageDialog, but don't know, how to add any textboxes to this dialog. Or maybe is this even not MessageDialog, but some kind of xaml file? As I say'd, i'm total beginner.

Answer 1

This is the CredentialPicker control.

There's an example of how to use it on MSDN.

Answer 2

First of all. Do you need call this dialog or create your own similar like this? If you need call this dialog than you should know that this is standart windows dialog and you can't add any additional fields. It shows when you call function XboxLIVEService.SignInAsync() inother case - create your own user control
