title: c# Check if point exist inside a polygon
body: <p>Hi I am looking to find a way of checking if a point exists inside a polygon from my c# code.I successfully implemented the same with javascript using <strong>Google maps geometry library</strong> as reference from <a href="https://stackoverflow.com/questions/6522484/google-maps-v3-check-if-point-exists-in-polygon#answer-16675416">this link</a>.Now I need to do the same from c# code.Is google providing any webservices or dll for the same?</p>
  
  <p>If not, can anyone suggest any third party api's or plugin's for the same purpose.I already tried some third party item's but didn't find any one giving accuracy like Google maps geometry library</p>
