Answer 1

The security model of Windows Phone 7 replaces various restrictions on what your application can do. One of these restrictions is that only one application can be running at any one point in time. This means it is not possible to run your applications 'above' others. Features such as the volume control pop-up are part of the WP7 OS and have not been created using the Silverlight framework that we, as developers, have access to.

You can set the "TopMost" property to True

form.TopMost = true;
