由於VS在開發WEB應用程序時，每次都需要重新啟動IIS Express，速度太慢了，如果改為手動控制IIS Express啟動，那么可以直接編譯應用程序后，直接刷新頁面，那么速度會更快。
因此需要常用的兩個命令為：
appcmd list site：列出IIS Express中包含的所有網站；
運行結果為：
C:\Users\Rising X>appcmd list site
SITE "WebSite1" (id:1,bindings:http/:8080:localhost,state:Unknown)
SITE "MVC5Demo" (id:2,bindings:http/*:12834:localhost,state:Unknown)
SITE "UserLimitMVC.UI.Portal" (id:3,bindings:http/*:15118:localhost,state:Unknow
n)
SITE "Admin" (id:4,bindings:http/*:28628:localhost,state:Unknown)
SITE "App.Admin" (id:5,bindings:http/*:1332:localhost,state:Unknown)
SITE "Company.Project1.Server.Host" (id:6,bindings:http/*:5000:localhost,state:U
nknown)
SITE "NtEfApp.Server.Host" (id:7,bindings:http/*:2452:localhost,state:Unknown)
SITE "AccountAtAGlance" (id:8,bindings:http/*:22764:localhost,state:Unknown)
SITE "langsinERP" (id:9,bindings:http/*:13253:localhost,state:Unknown)
SITE "AngularDemo" (id:10,bindings:http/*:20555:localhost,state:Unknown)
SITE "WebAPIDemo1" (id:11,bindings:http/*:21023:localhost,state:Unknown)
SITE "WebAPI" (id:12,bindings:http/*:4115:localhost,state:Unknown)
SITE "WebApplication1" (id:13,bindings:http/*:25974:localhost,state:Unknown)
SITE "RightMng" (id:14,bindings:http/*:27057:localhost,state:Unknown)
其中id:序號，對應的為應用程序的序號。
2.IISExpress /siteid:序號 ，此命令啟動指定序號的應用程序，那么此應用程序則將一直在運行。
為了能使命令行窗口中可以直接使用此兩命令，需要把IIS Express所在的文件夾路徑添加到系統的路徑參數中。
