Finally to end on a quick tip – Assuming you install on a machine without Visual Studio 2010 the “Visual Studio 2010 Express for Windows Phone” displays a simpler user interface than its big brother. You can quickly enable extra goodness by going to Tools > Settings > Expert Settings. This enables more menu and toolbar options and is definitely worthwhile if you are already familiar with Visual Studio.
