Hi friends.
please help me with this problem, i've searched it for a day but i couldn't solve it!

I use Visual Studio 2012, ASP.NET, c#.

I've created new website ( not web project ),
In solution explorer right click on project and clicked Add Service Reference

then I've add a web service provider address, a new folder named App_WebReferences created. It contains ServiceReference1 folder in which there are three files(two .svcinfo and one .wsdl).

Now I use this code as my provider guided:

var srv = new ServiceReference1.PaymentIFBindingSoapClient();
    double result = srv.verifyTransaction(refNum, "10004738");

there is no error in compilation and running in localhost.
BUT
when I upload my website files to my ftp on the server..I get this error message:

*Server Error in '/' Application.
 Compilation Error

I've stuck in this problem.
Whats the problem!?
How should I solve it?
PLEASE help me !!

I should say that I tried to add this line:

using ServiceReference1;

then the error message line changes to this line with the same message !

and again no error message in localhost running!

my website is build in .Net Framework 3.5

thanks in advance.
