Object Binding Utility

I like the clean separation of public and domain objects (so nHibernate won't help here) from each other, which makes me write a lot of code to map one object to another. What tools / plugins are there to do the tedious manual execution of this mapping in .NET? M Whenever I do this on Google, he thinks that I want to do ORM, which I am not looking for. Thanks!

EDIT 19: 33CST: Well, I wrote a very simple application (very quickly written code) demonstrating what I'm looking for. I'm just wondering if there is a VS plugin that will do this for me.

So, a seemingly unsatisfied solution at runtime, I wrote a small utility that will create mappings in the code. You can download the source below and write better error handling, etc. Etc. I would appreciate any interesting changes you made, it was done in a hurry, but it works. Please keep in mind that the code is released under the LGPL .

Object Mapping Utility Source Code

UPDATE JUNE 23, 2009 . I made some updates to the code that cleaned it up (a little), and also added the ability to save the mapping to a file so that it can be modified later.
