Basically it returns EmptyResult after response is sent.

public ActionResult GetFile()
{
    string theFilename = ""; //Your actual file name
        Response.Clear();
        Response.AddHeader("content-disposition", "attachment; filename="); //optional if you want forced download
        Response.ContentType = "application/octet-stream"; //Appropriate content type based of file type
        Response.WriteFile(theFilename); //Write file to response
        Response.Flush(); //Flush contents
        Response.End(); //Complete the response
        System.IO.File.Delete(theFilename); //Delete your local file

        return new EmptyResult(); //return empty action result
}
