I'm currently working on a relatively large MVC project I would like to organize vertically.
Why break convention? And, in more detail here
As far as implementation goes, the plan is a VirtualPathProvider. My question is, what would the best way be to give this VirtualPathProvider knowledge of the feature folder names?
e.g. ~/Features/{Feature}/View1.cshtml
If you plan to do this, I would definately NOT use a VirtualPathProvider. The reason is that path searches are expensive. The more paths you have, the longer it takes to find them.
I would instead specify paths directly. You lose the convention aspect, but you gain performance.
