Answer 1

You can use the various overloads of the File() function in controllers that inherit from Controller or ControllerBase.

For example, you can do:

return File("~/Images/photo.jpg", "image/jpeg");

This uses a virtual path, other options include giving it a byte array or a Stream. You can also give a download file name as a third argument if that is needed.
