Hi all,

I am using Visual Studio 2019 (Version 16.11.17) and am trying to create a C++ Class Diagram.

When I try to use components from the Class Designer toolbox, I see that only 'Pointer', 'Comments' are available - all other components are greyed out and not useable.
I am also unable to use these toolbox components from the context menu (i.e. Right-click -> Add -> 'Comments' is only shown).

I have not been able to find the answer to this question on any Microsoft or SO thread.

Please help me use this tool!

    Hi @Ryan Kaye-Simmons ,

    Welcome to Microsoft Q&A!

    It is designed like this.

    For C++ project, the Class, Enum, etc. are disabled by default in Class Designer toolbox.

    If you have any suggestion about the feature, you can upvote this ticket and directly report to product team.
