title: Implementation Secure messaging in EHR through Direct protocol
body: <p>I'm working on EHR secure messaging in ASP.NET. I have already configured the direct project on virtual machine. Now I have no clue where to start, I want to integrate my EHR application with STA/HISP in order to achieve secure messaging. Is there any service which I need to publish, to integrate STA/HISP with my EHR application. </p>
  
  <p>Any answer will be very helpful to me.</p>
