Hi I have some major problems with auto mapper and it being slow. I am not sure how to speed it up.
I am using nhibernate,fluent nhibernate and asp.net mvc 3.0
Not sure if this is causing any issues in your case, but beware of serializing auto-implemented properties.
Each time your code is compiled, the name of each (anonymous) backing field is picked at random by the compiler. So you may see some surprising exceptions if you serialize data with a progran that is compiled at one time and de-serialize it with a different program.
