title: Identity and Access is Missed in VS 2015
body: <p>Need to add STS to my web project, and I got some guide from my colleague:</p>
  
  <p><strong>Add STS Reference command by right-clicking the web project in Visual Studio and select Identity and Access</strong></p>
  
  <p>but I can't find it in my VS 2015. Have tried to search it in a google, but failed.
  Can somebody tell me, how i can add this service to my project?</p>
