Review of Applying Domain-Driven Design and Patterns
So let's assume we want to use PI. What's it all about? Well, PI means clean, ordinary classes where you focus on the business problem at hand without adding stuff for infrastructure-related reasons. OK, that didn't say all that much. It's easier if we take a look at what PI is not. First, a simple litmus test is to see if you have a reference to any external infrastructure-related DLLs in your Domain Model. For example, if you use NHibernate as your O/R Mapper and have a reference to nhibernate.dll, it's a good sign that you have added code to your Domain Model that isn't really core, but more of a distraction.
