Install a UML profile
You can extend Visual Studio with a UML profile. A profile lets you add stereotypes and additional properties to the elements you can create in UML models. To see which versions of Visual Studio support this feature, see Version support for architecture and modeling tools.
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
On the Visual Studio Tools menu, click Extension Manager.
Click the extension that you want to remove, and then click Disable or Uninstall.
