If I understand correctly then you are asking specific to asp.net core. In ASP.net core HttpResponseMessage is not a way to return result the way we used to do in ASP.net web api 2.

In asp.net core ( WEB API ) simply look like this.

[HttpGet]
public IActionResult Get()
{            
    Byte[] b = System.IO.File.ReadAllBytes(@"E:\\Test.jpg");   // You can use your own method over here.         
    return File(b, "image/jpeg");
}

Note: As you mention that in Fiddler Imageview you see message like this "his response is encoded, but does not claim to be an image." because ASP.net core consider HttpResponseMessage as simple class and convert into json or xml.
