Tool like magic draw but for generate C# code

It's there a plugin for visual studio or a specific program that allows to draw an UML model and generates the classes for C#?? and more, for example Creates a repository classes from classes entities o开发者_Go百科f the entity framework generates

Visual Studio has had the Class Designer built in since Visual Studio 2005, though not all versions (the Express versions don't have it).

A former co-worker swore by http://www.sparxsystems.com.au/products/ea/index.html. The generated code definitely needed some tweaking though. Or something like http://staruml.sourceforge.net/en/index.php might have plugin's to generate needed c#...or perhaps t4.
