While preparing for 70-536 I finally approached the topic of code access security and, just like I feared, it is not easy. No wonder it didn’t get the wide adoption that Microsoft hoped for. CAS does not fall into pit of success. It is much easier to do the wrong thing as opposed to being very easy to do the right thing.

While looking for more info on CAS I found this good post that clarified some of the things for me. Maybe it will help you as well.
