Hi Martijn,
There are many ways to skin this cat, but my way would be: Open all files from this project on a simple text editor like NotePad++ and perform a search/replace for "DotNetNuclear.Modules.ViewsTutorial" to the new name you would like to give.
That is my unorthodox way of doing it.
I hope it works for you. Maybe Scott has a different suggestion.
Cheers,
Aderson
