title: Developing GIS application for windows phone 7 and 8
body: <p>I am planing to start a GIS application for windows phone (7 and 8) and I have some important questions. Any idea will be appreciated!</p>
  
  <p>1- Database Engine for WinPhone. Is SQLServer Compact the only option for database engine? Is there an alternative?</p>
  
  <p>2- Does SQLServer Compact (or its alternative) support Spatial data?</p>
  
  <p>3- Is there any libraries suitable for works like processing geo-spatial data? Rendering such data?...</p>
