Extend UML models and diagrams

Starting with Visual Studio 2017, the UML Designers have been removed from Visual Studio. For more information, see this blog post.

If you still need to use UML, you can use Visual Sudio Enterprise 2015, which is side-by-side compatible with later versions of Visual Studio.

For information about using UML in Visual Studio 2015, see:
