View Class Diagram Missing

Question

In Visual Studio 2015, the view option is missing class diagram as represented in the following image. I have tried Enterprise Architect but that software is unable to detect C# 6 syntax. For example whenever there's public static String readonlyText => "123";, it skips the class.

What's the solution to generate class diagram based on ASP.Net Core code?

Answer 1

In Class View (Ctrl+Shift+C) Right click a namespace or class, and you should see the 'View Class Diagram' option. Useless tho, nothing happens when you click it.
