TL;DR; Visual Studio 2010 introduces support for UML, enabling developers to create and manage Unified Modeling Language diagrams directly within the IDE.

Just in case you have been living in a shed at the bottom of the garden, Visual Studio 2010 is to support UML. As you can see from my diagram, my UML skills are a little, erm, crude. But I think you will get the picture and if you want to do better then just download

As I have not used UML since university so I do not know if this feature will meet the needs of those that use UML extensively, but I would expect that a lot of time and investment has gone into this area, and if it is lacking in some minor but crucial feature, there is still time to get some changes made…maybe…
