在Vista IIS 7上寫了一個WCF服務，正想用http: //localhost/MyWebApp/MyWCF.svc看一下有無成功執行，結果傳回以下錯誤:

HTTP Error 404.3 - Not Found

The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

查了一下，在IIS7上跑WCF要動點手腳，得執行ServiceModelReg.exe註冊WCF: (注意要用Admin身份跑，最簡單的方法是 開始->執行->cmd，然後ctrl-shift-Enter，就會以Admin身份開始命令視窗)

C:\Windows\Microsoft.NET\Framework\v3.0\Windows Communication Foundation>servicemodelreg –i
