Adding this answer because those comments are easy to miss (like I nearly did).

Suggested by Jussi Palo (using a PhysicalFileResult):

[HttpGet]
public IActionResult Get()
{        
    return PhysicalFile(@"E:\\Test.jpg", "image/jpeg");
}

• A nice single liner that handles things like 206 partial.

Suggested by Tseng (using an overload of the FileContentResult constructor that accepts a stream):

[HttpGet]
public IActionResult Get()
{        
    FileStream stream = File.Open(@"E:\\Test.jpg");
    return File(stream, "image/jpeg");
}

• Useful if your stream is coming from somewhere else (like an embedded resource).

For RL remember to check the file/resource exists, and return 404 if not.
