教一跨行同事學C#，我想從基礎的講一下，也就是最基本的面象對象分析與設計（OOAD），我直接打開我最新安裝的 visual studio 2017。准備建一個“建模項目”。結果發現死活找不到？打開一個老項目也無法生成UML圖？果斷Google之
在這里：https://docs.microsoft.com/en-us/visualstudio/porting/port-migrate-and-upgrade-visual-studio-projects,找到如下描述：
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 architectural dependencies is no longer performed 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).

好吧，只能坐等大神擴展了，這么好的功能盡然移出了？
