Prefer: return=representation not respected

[dustinmoris]

When I send a HTTP POST request to /Patient with a If-None-Exist and Prefer: return=representation headers then the current server implementation doesn't return me an existing patient in the response. The server only responds with a 200 OK and an empty HTTP body, but my understanding is that I should get back the entire Patient resource as well.

I am using the official .NET FHIR client which has support for a conditional create which is supposed to do exactly that according to the FHIR spec. It seems the microsoft fhir server doesn't implement this correctly at the moment.

I did a quick search on GitHub and I believe the bug is located here where you simply return an empty Ok() instead of also checking for the Prefer HTTP header and return the full representation if that was specified.

Thanks @dustinmoris, you are correct, this feature is not implemented yet

Any idea when this issue will be "grabbed up"?
