Does Visual Studio Team System support behavioral modeling and Use Case diagrams?
Yes, behavioral modeling and Use Case diagrams with code generation and reverse engineering are supported via Visio for Enterprise Architects, which is included with Visual Studio Team System. Visual Studio Team Edition for Software Architects, however, does not natively support these diagram types. Custom diagram types can also be created on top of the powerful Visual Studio 2005 modeling framework using the recently released Microsoft Tools for Domain Specific Languages.
