I preferred a solution which returned an HttpResponseMessage. I liked the simplicity of Risord's answer, so I created a stream in the same manner. Then, instead of returning a File, I set the HttpResponseMessage.Content property to a StreamContent object.

return new HttpResponseMessage()
{
    Content = new StreamContent(fs)
};
