Error when trying to add a Service Reference

Question

I´m trying to create a client in C# to a web service which (I suppose) is written in Java. It´s my first time trying to write a client, so I´m following the instructions on MSDN, but I´m stuck on a problem with Add Reference. When I open the Add Service Reference dialog and add the URL, an error occurs:

There was an error downloading 'http://geoportal.cuzk.cz/WCTService/WCTService.svc'.
The request failed with HTTP status 404: Not Found.
Metadata contains a reference that cannot be resolved: 'http://geoportal.cuzk.cz/WCTService/WCTService.svc'.
There was no endpoint listening at http://geoportal.cuzk.cz/WCTService/WCTService.svc that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
The remote server returned an error: (404) Not Found.
If the service is defined in the current solution, try building the solution and adding the service reference again.

What should my next step be? I don´t know what I should do with this! (It is a coordinates-transformation service from the Czech Republic.)

I was facing a similar situation in which I had created a WCF Service (Employee.svc) and later changed the named to EmployeeService.svc. WCF project compiled just fine but when I was trying to add service reference from by UI Client, I was getting following error:

Metadata contains a reference that cannot be resolved: 'http://localhost:2278/EmployeeService.svc?wsdl'.
The document format is not recognized (the content type is 'text/html; charset=UTF-8').
Metadata contains a reference that cannot be resolved: 'http://localhost:2278/EmployeeService.svc'.
There was no endpoint listening at 'http://localhost:2278/EmployeeService.svc' that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
The remote server returned an error: (404) Not Found.
If the service is defined in the current solution, try building the solution and adding the service reference again.

I resolved it by replacing the correct service class name everywhere. In my case, it should have been EmployeeService and NOT employee. The left out place was in the markup code of svc file:

<%@ ServiceHost Language="C#" Debug="true" Service="WCFServiceHost.**Employee**" CodeBehind="EmployeeService.svc.cs" %>

Changed it to

<%@ ServiceHost Language="C#" Debug="true" Service="WCFServiceHost.**EmployeeService**" CodeBehind="EmployeeService.svc.cs" %>

And it started working again!!! Dont forget to build your WCF project after changing the service name.
