To design, edit, and refactor classes and other types, add a class diagram to your C#, Visual Basic, or C++ project. To visualize different parts of the code in a project, add multiple class diagrams to the project.

You can't create class diagrams from projects that share code across multiple apps. To create UML class diagrams, see Create UML modeling projects and diagrams.

Install the Class Designer component

If you haven't installed the Class Designer component, follow these steps to install it.

  1. Open Visual Studio Installer from the Windows Start menu, or by selecting Tools > Get Tools and Features from the menu bar in Visual Studio.

    Visual Studio Installer opens.

Add a blank class diagram to a project

    The Add New Item dialog opens.

  2. Expand Common Items > General, and then select Class Diagram from the template list. For Visual C++ projects, look in the Utility category to find the Class Diagram template.

    Note

    If you don't see the Class Diagram template, follow the steps to install the Class Designer component for Visual Studio.

    The class diagram opens in Class Designer and appears as a file that has a .cd extension in Solution Explorer. You can drag shapes and lines to the diagram from Toolbox.

To add multiple class diagrams, repeat the steps in this procedure.
