app without a window

Question

hi
MultiPage

the above project just have two pages and no windows.

Q1: how this works without window , where the Page control needs a host (frame) ?
Q2: when we use user control without code behind file (usercontrol.xaml only) ?
(or what is differences between a control with/without code behind)

thanks in advance

Answer 1

A1:Page can be implemented as root element in Xaml file and can contain single element similar to window. The table shows the type of application that these resources can be set as the StartupUri, you can see the StartupUri in the App.xaml.

A2: The x:Class which in xaml code configures XAML markup compilation to join partial classes between markup and code-behind, if the xaml without it, it can be also used to the UI design.
