C＃WCF ChannelFactory BadRequest 400錯誤

我已經創建了一個簡單的web服務服務器，但要在同一個項目中調用服務類中的方法，我創建了一個webchannelfactory代理。一切工作正常，直到我將項目（或exe版本）移動到另一臺機器。我無法弄清楚發生了什麼事情！C＃WCF ChannelFactory BadRequest 400錯誤

我收到此錯誤信息：

The remote server returned an unexpected response: (400) Bad Request.

與堆棧跟蹤：

代碼：

WebChannelFactory<Client.IClientService> factory = new WebChannelFactory<Client.IClientService>(hostUri); 

Client.IClientService proxy = factory.CreateChannel(); 

proxy.dosomething(); // Error shout here on Machine2

在此先感謝

EDIT1：當t他的例子中，沒有客戶端（我已將客戶端命名爲此服務器）。正如我所說的，它的代碼在另一臺機器上都沒有錯誤（都使用localhost）。

<?xml version="1.0"?>

     <appSettings> 
     <system.serviceModel>

EDIT2：

在瀏覽器中，我得到這個：

服務器遇到錯誤處理請求。消息的例外情況是'Client.ClientService'的類型初始值設定項引發了一個異常。'。查看服務器日誌獲取更多詳細信異常堆棧跟蹤是：

問題解決了。

服務利用數據庫，所以當我複製項目到一臺新機器，我忘了創建一個新的數據庫。
