title: WebApi Controller Lifecycle
body: <p>So, here's the deal.</p>
  
  <p>I have a WebApi with a number of Controllers. I have an Identity Server configured to to Authentication. This all works.</p>
  
  <p>When I make a call on the API and I pass the appropriate token, if I put a breakpoint in any of the Actions of the Controller, the User object is properly populated.</p>
  
  <p>Now, the code that the API Actions execute needs data related to the authenticated user. If I attempt to execute this code in the constructor of the Controller my code fails because User is not yet properly populated.</p>
  
  <p>So, to my question: is there some element of the Controller's lifecycle, that I have yet to discover, that will allow me to execute code for every call on the Controller (like it would in the constructor) but where the User object has been properly populated?</p>
