## 2.Default files in the new MVC project

* App\_Data   
  * Stored database.
* App\_Start
  * RouteConfig.cs
    * 當request符合url的規則時, 就會進行相對應的action及呼叫相對應的controller
    * 當request不符合url的規則時, 就會導入default的action及呼叫default的controller
    * url的規則是controller/action/id         

      ```
      routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
      );
      ```
    * 如果有個request是movies/popular, 則他會被送到MovieController的Popular()
    * 如果有個request沒有指定action, id, 或controller, 則他會被送到default
  * BundleConfig.cs
    * 設定js, css等bundle       
* content : css files
* controllers
* fonts
* models
* scripts: js files
  * views: 與model的檔案是相對應的
    * shared
      * \_Layout.cshtml: 主頁面, @RenderBody()會再去呼叫controller對應的view頁面
* Global.asax.cs: 程式的進入點
* packges.config: 管理nuget套件的config, 如同npm
* startup.cs
* web.config
