Visual studio 2017 no modeling project ?, Studio2017

Teaching a cross-row colleague to learn C #. I 'd like to give a basic introduction, that is, the most basic facial object analysis and design (OOAD ), I directly open visual studio 2017 that I recently installed. Prepare to create a "modeling project ". Why can't I find it? A uml diagram cannot be generated even when an old project is opened? Decisive Google

Here: callback:

If you allow Visual Studio to update the project automatically, you can open it in Visual Studio 2015, Visual Studio 2013, or Visual Studio 2012.

The format of the modeling project has not changed between Visual Studio 2015 and Visual Studio 2017 and the project can be opened and modified in either version. however, there are differences in behavior in Visual Studio 2017:

• Modeling projects are now referred to as "Dependency Validation" projects in the menus and templates.
• UML diagrams are no longer supported in Visual Studio 2017. UML files are listed in the Solution Explorer as before but will be opened as XML files. use Visual Studio 2015 to view, create, or edit UML diagrams.
• In Visual Studio 2017, validation of specified tural dependencies is no longer formed med when the modeling project is built. instead, validation is carried out as each code project is built. this change does not affect the modeling project, but it does require changes to the code projects being validated. visual Studio 2017 can automatically make the necessary changes to the code projects (more information ).

Well, I can only wait for the great gods to expand. So all these good functions have been removed?
