With this tool I achieved more in 5 minutes than with Microsoft and opensource documentation in two days. It's not an exaggeration if I say that every developer is able to create at least working skeleton of IE plugin in 15 minutes. Add-in Express for IE has excellent documentation and is extremely easy to use. ROI is obvious and very quick as this tool gives a great quality for the price it costs. With Add-in Express for IE templates for Visual Studio you not only create plugins in 5 minutes. This tool also creates the whole project structure as well as the Setup project that enables your users installing the plugins in the user-friendly manner. And it takes only few clicks! I love it.
