User kokos answered the wonderful Hidden Features of C# question by mentioning the using keyword. Can you elaborate on that? What are the uses of using?

Updating the using keyword was specifically for templates, and (as was pointed out in the accepted answer) when you are working with non-templates using and typedef are mechanically identical, so the choice is totally up to the programmer on the grounds of readability and communication of intent.
Not using by means that the technology used is incidental, and the focus is on the approach being shown to be feasible. Without more context it's impossible to say what the intended import of the sentence is and whether by would actually be better or not.
