WCF Services using same entity model class but exposes different in client

Question

I am new to WCF Services and can't get rid of this problem. For the next version of our web application I want to make use of WCF as webservice. Currently I am stuck with this problem:

To try WCF out I made 2 services: EmployeeService and AuthenticationService. I also made a datacontract Employee .

In AuthenticationService I use EmployeeService to get the logged Employee

Now in my client (ASP MVC Web) I add both Services as I need them both. But then when I try to use the object Employee I get the error :

Employee' is an ambiguous reference between 'IWA.Portal.AuthenticationService.Employee' and 'IWA.Portal.EmployeeService.Employee

The reason I want to make multiple services is to group them functionally. Example: Everything regarding employees will be under EmployeeService and everything regarding job will be under JobService.

How can I fix this or how should I structure my webservice?

Currently my webservice solution consists of :

• Project.DataContracts (Entities)
• Project.ServiceContracts (Interfaces)
• Project.Services (Services, NHibernate & Castle Windsor)

Any help is much appreciated! Thx

AuthenticationService

public class AuthenticationService : IAuthenticationService
{
    private readonly IEmployeeService _employeeService;

    public AuthenticationService(IEmployeeService employeeService)
    {
        _employeeService = employeeService;
    }

    public Employee Authenticate()
    {
        var employee = _employeeService.Get(1);

        return employee;
    }
}

Code in my client (Controller)

    readonly EmployeeServiceClient _employeeService = new EmployeeServiceClient();
    readonly AuthenticationServiceClient _authenticationService = new AuthenticationServiceClient();

    Employee authedEmployee = _authenticationService.Authenticate();
    Employee test = _employeeService.Get(827);

Looks like your namespaces are clashing and to fix it you will need to use full names in your code when referring to a class so instead of just Employee use

AuthenticationService.Employee auth_emp = new AuthenticationService.Employee();

and

EmployeeService.Employee es_emp = new EmployeeService.Employee();

This will solve your problem.
