title: Protecting .NET framework 4.x web API with Identity server 4 in
body: <p>I am working with identity server 4, and I know it is now on ASP.NET Core, and it is fine.</p>
  
  <p>But I have a <a href="https://en.wikipedia.org/wiki/ASP.NET_MVC_Framework#Apache_License_2.0_release" rel="noreferrer">Web API</a> application that is on .NET 4.6.2. I wonder how is possible to protect these APIs. Or is it possible at all? Or I should change my web API to ASP.NET Core?</p>
  
  <p>I searched everywhere, but all samples are with ASP.NET Core.</p>
