This started as a standard way of setting up most projects I work on. The folder structure provides a quick template to get an empty solution working. When I am less busy and lazy I will create a Visual Studio template for this. Then I can get a new project up with this structure just by creating a new solution.
I also started on some core interfaces and infrastructure that is common across projects. The goal is that I can include these projects and get the base core architecture without having to rewrite it. There is still a lot to do. I am a big fan of the Onion Architecture and the goal of this little project is to eventually grown into an implementation of Onion.
I guess I should explain the name. My wife's nick name is Dutchess. She likes to watch this crazy cartoon named Archer and the main character, Archer, his code name is Dutchess. So, my wife says that her code name is Archer. Well Archer kind of reminds me of architecture so it was only natural to name it Archer and the code name of the first release is Dutchess...make sense right?
