Dofactory has a 3.5 framework for developing software and includes some design patterns which are explained in a document. There's a sample app built using the framework which has user interfaces for WinForm, WPF, ASP.NET (WebForms), ASP.NET MVC, plus DAL's using Linq & ADO.NET which makes it a candidate for a learning tool and a framework to be used in real world apps.
I am not sure about the quality and ease of use of the framework. I would like to hear opinions from people who actually used it and from ones who hear stories about it.
I am also interested in similar good frameworks which include a DAL and business layers (beside CSLA).

I have used DoFactory 2.0, I really like the documentation which came with it. especially where it showed where design pattern were used in the .Net framework.
the framework was good, in the sense that i was able to get to grips with what goes where. I liked how it included some of the PEAA patterns. I would be very interested how the MVC and WPF clients have been implemented.
before you buy this have a look at S#arp Architecture
which has a full pledged orm, IoC, MVC, WCF, Domain Driven, Unit Testing, Validation, each of these tools are based on patterns... also look around the site, its has good documentation
