You can extend Visual Studio Ultimate with a UML profile. A profile lets you add stereotypes and additional properties to the elements you can create in UML models.
If you receive a UML model that has been created using profiles, some properties will not be displayed unless you install the same profiles.
A profile is distributed inside a Visual Studio Extension. An extension might also contain other features such as menu commands. For more information, see Managing Visual Studio Extensions.
To install a UML Profile on your computer
- The profile should have been given to you in the form of a Visual Studio Extension (.vsix) file. There might be other features in the same file. - Move the .vsix file to a convenient location on your computer. 
- Double-click the .vsix file in Windows Explorer (or File Explorer), or open it within Visual Studio. 
- Click Install in the dialog box that appears. 
- To uninstall or temporarily disable the extension, open Extension Manager from the Tools menu. 
To uninstall or disable a profile extension
