Console application consuming wcf service

See more:

WCF

ASP.NET4

I have a c# asp.net web application/projct which is working well. Later I added a wcf service as new item to this proj. Then I add a new simple Console application to this solution to consume the wcf. It works fine in my local. (My local server name is A. Using http://A/MyProjName/wcfSendRpt.svc OR http://localhost/MyProjName/wcfSendRpt.svc both Okay).

Then I published my web application( with the wcf service) to live server B. (B just host this only web-application. ) Both http://B/wcfSendRpt.svc OR http://localhost/wcfSendRpt.svc works fine.
Then I deployed my Console application to server B. ( I just copyed the exe and config files to sever B). I changed the endpoint address in config file from "http://A/MyProjName/wcfSendRpt.svc" to "http://B/wcfSendRpt.svc" like below

<endpoint address="http://B/wcfSendRpt.svc" 
	binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IwcfSendRpt"
        contract="nsSendRpt.IwcfSendRpt" name="BasicHttpBinding_IwcfSendRpt" /> 

But it doesn't work. The error from event view is like below,

 Unhandled Exception: System.ServiceModel.FaultException`1[System.ServiceModel.Ex
ceptionDetail]: An error occurred while executing the command definition. See th
e inner exception for details.

My console application is very simple: the code is like below

class Program
    {
        static void Main(string[] args)
        {
            nsSendRpt.IwcfSendRptClient ss = new IwcfSendRptClient();
            string a = ss.SendRpt(System.DateTime.Now.ToString("yyyyMMdd"));
            ss.Close();
        }
    }

I need your help to solve this. And I am pretty new in wcf. Is this wcf service in my web application is restful?

Thanks a lot
