Windows Phone: Taking screenshots for marketplace submissions

When you submit your application to the marketplace, there’s an option for including screenshots. However, your submission will be rejected if the screenshots aren’t exactly to spec: They must be 480x800, and not include any of the emulator chrome.

Taking a specific snippet is difficult because you either have to manually select just the right area, or to resize things after the fact. Here’s the easy way:

1. Set the emulator window to 100% size, so that it uses a 1:1 pixel ratio.
2. Start the Windows Snipping tool.
3. The “New” button has a dropdown beside it. Change it to “Window Snip”.
4. Click once within your emulator window.

The emulator has an internal window for the phone screen, so you end up with a perfect 480x800 sized screen cap.
