they have the styles and templates for WPF and Silverlight controls published on MSDN. but not for the WP7 controls.
So, how to get the default style and control template of WP7 control ?
In your SDK folder
C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v7.0\Design
or
C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v7.1\Design
You will find System.Windows.xaml and ThemeResources.xaml as well as folders for eah of the themes.
