The key items in the project were:
1. Assume WVGA model ( 480 x 800 pixels)
2. Add a view box to enable scaling of the window
3. Add a KerningTextBlock control to get text closer to Windows phone, thanks to Danteq for this code, by enabling a text kerning in Silverlight 3, though I had to change from Padding to Margin to support negative trackingproperty.
4. Use of the windows font Segoe UI
