title: .Net 4.0 Owin Authentication Example
body: <p>Does anyone know the reference page for implementating Owin Authentication for .Net 4.0 Web application?</p>
  
  <p>I could only find the examples for .Net 4.5. Unfortunately my application was build on .Net 4.0.</p>
  
  <p>I would appreciate for any resources.</p>
