I'm looking for UML software that mainly allows me to design class diagrams and sequence diagrams. A requirement is "reverse engineering" of C# code to diagrams. This because we will most certainly be changing things around in our code and going back to change the UML manually is just a pain in the ass. Free software is preferred ofcourse, but I'd like to hear about all software you can recommend. I tried VS 2005 but it doesn't have sequence diagrams, or does it?!

Enterprise Architect does this.
