title: How to find latitude and longitude using C#
body: <p>I have a <code>WCF</code> service in C#.</p>
  
  <p>In the Service call client sends a city name. I want to convert the city name to latitudes and longitudes and store in Database under demographics.</p>
  
  <p>I am planning to use Google API to implement above functionality.</p>
  
  <p>I have obtained an API key from Google and its of type 'Service account'.</p>
  
  <p>How can I obtain the latitude and longitude using which APIs?</p>
  
  <p>Do I need to install some <code>SDK</code> or any <code>REST</code> Service will do?</p>
