If you can’t get class diagrams to work in Visual Studio 2017, this video shows you how to enable the feature in Visual Studio 2017.
As Dawid1879 points out in a very valuable comment, below, you may have to change the language from your native language (within the OS) to US English to enable access to some of the tools available in Visual Studio 2017.
I ran the solution suggested by Dawid1879 and found that you should reset the OS to your native language after you have enabled the tool[s] you want.
If you run into any problems, try restarting your computer.
A big thank you to Dawid1879 for the observation and for taking the time out provide a comment about it.
