title: Visual Studio 2013 debug session stops 1 minute after logging in with AspNet Identity
body: <p>Maybe the answer is trivial, but I couldn't find the exact same behavior in other threads.
  I have an MVC 5 web application. I implemented custom identity database with Asp.Net Identity 2 (Owin). I have only external login (facebook, google...etc). The login works fine. The users got authenticated with roles and everything.</p>
  
  <p>After one minute of inactivity, my Visual Studio 2013 debug session stops. Sometimes the application remains available (so IIS App Pool is not stopped) sometimes it recycles IIS as well. </p>
  
  <p>I also implemented logging in Application_End Global.asax method in order to have the shutdown reason, but in these cases there is no info in the logs. In other cases, when the App pool is recycled due to web.config change I do have info in the logs.</p>
  
  <p>I suspect timeout, however I have no clue what kind of timeout it could  be. Where should I look?</p>
  
  <p>Thanks in advance.</p>
