Official WP7 UI Design Template Released, 28 PSDs Directly from Microsoft

Microsoft has released - well hidden in its documentation - a design template for Photoshop which consists of 28 PSD files and therefore includes most of the design elements used in Windows Phone 7. Though this is primarily intended for designers who need to mock up the interface for an application (in which case you should also check out the UI Design and Interaction Guide), it's also a very useful resource for creating custom themes and skins based on the Metro design of Microsoft's upcoming mobile operating system. To quote the MSDN page:

A collection of 28 layered Photoshop template files that can be used to create pixel-perfect application layouts, to help guide UI development, or to pitch an idea. These design templates showcase many controls that are a part of the Windows Phone Developer Tools Beta. They also include examples of controls that are a part of Windows Phone, but are not available as a part of the Windows Phone Developer Tools. These additional templates are included to help designers and developers maintain a consistent look and feel across applications for system controls that developers wish to mimic. Templates in the download: Application Bar & Application Menu, Buttons, Check Box, Context Menu, Date Picker, Dialog Boxes, Edit Control, Hardware, Icons, Keyboard & Input, List Picker, List View, Panorama, Panorama Backgrounds, Picker Box, Pivot, Progress Indicators, Quick Jump Grid, Radio Button, Reminders, Slider, Start & App List, Start Tiles, Status Bar, Theme, Time Picker, Toast Notifications, Toggle Switch
