3, wwwroot (at stations directory)
This is the root directory, after opening the can see there is a css, and js files. The actual point that, after you've published your project, that he is not with the project to generate a DLL (this is nonsense, css, js files has always been not generate dll's), if the need to change the style here changes directly on it, total styles can not be changed once released it.

ConfigureServices将服务添加到服务容器，使其在应用和 Configure 方法中可用。 服务通过依赖关系注入或 ApplicationServices 进行解析。
Configure 方法用于指定应用响应 HTTP 请求的方式。 可通过将中间件组件添加到 IApplicationBuilder 实例来配置请求管道。（中间件具体将在ASP.NET Core 基础知识（六）中间件介绍）
