I was wondering how people think about using productivity tools like Coderush or Resharper in live demos. Is it a don't and should someone only use the most default settings of the IDE? Or is it ok to speed things up a little during the demo? Also, should you explain you are using this tool during the demo?
I've seen a lot of presentations where people use these tools and personally I don't mind.
Make sure you tell people that are going to be using the tool and then announce the action that you are about to take. e.g. "I'll use Resharper to extract this method into the Foo class"
