title: Generate WebAPI documentation in swagger json format
body: <p>I have created a WebAPI using .Net 4.5 and want to document this API using <a href="https://github.com/wordnik/swagger-core/wiki">Swagger</a>.
  I have added <a href="https://github.com/wordnik/swagger-ui">swagger-ui</a> in my .Net project. Now when i browse to ../swagger-ui/index.html it successfully opens <a href="http://petstore.swagger.wordnik.com/api/api-docs">pet store api-docs</a> (json) in swagger UI format.</p>
  
  <p>My question is how can I create such (swagger) json for my WebAPI controllers and models? As I have put in required XML summaries/comments to c# classes and attributes.</p>
  
  <p>I saw that <a href="https://github.com/Swagger-Net/Swagger.Net">Swagger.Net</a> and <a href="https://github.com/domaindrivendev/Swashbuckle">Swashbuckle</a> are there doing similar things but I could not really understand how to generate swagger-json file using any of them. There might be very small mistake I am doing but unable to point out.</p>
  
  <p>Please help.</p>
