I have a small site I developed for a friend that uses ASP.Net MVC and was wondering if I could hook it up to dotnetnuke or another CMS. Or is doing an admin site using dynamic data?
I wish there was a good CMS in MVC. However MVC isn't even RTM yet! The thing with current .NET CMSs are that they don't handle URLs very well. I'm hoping a CMS built on MVC will pop up at some point.
Take a look at OpenSourceCms.com, they might have what you're looking for or the demos there might at least help lead you to an answer.
Oxite might be the closest to what you are after at the moment although I think it is more of a blog engine.
Here is a list of a few ASP.NET MVC based CMS's. However these are not based on the current release candidate but I think they are a pretty good start.
N2 Open Source ASP.NET CMS http://n2cms.com/
Oxite http://www.visitmix.com/Lab/Oxite
Hydrogen CMS http://www.hydrogencms.net/Home.aspx
Take a look to Kooboo (kooboo.com). A simple to use and flexible CMS based upon ASP.NET MVC.
