title: Service method called twice
body: <p>I have created a rest service using wcf.
  I am writing Entity framework code within a service method to fetch data from database.</p>
  
  <p>Every call from browser is hitting the service method twice or thrice.
  I found no exception within the method. I encountered same problem before and solved it adding DataContract attribute to all the models(not helping now).</p>
  
  <p>What may be the possible reasons? Please help.</p>
  
  <p>Regards
  Ashish</p>
