不能隐含转换类型通用列表错误MVC WCF

Question

我正在使用MVC和WCF服务。我的MVC项目和WCF服务在同一个解决方案中。我在mvc项目和wcf服务项目中有相同的客户类。 我在服务返回List<Customer>中编写了一个方法，我想在mvc项目中调用此方法但是我有一个错误，如＆＃34;无法将类型<x.Customer>转换为<y.Customer>＆＃34 ;

无论如何我改变了像Generic.List这样的服务引用配置，但是我有同样的错误。我该如何解决这个问题？

public class ReportService : IReportService
{
    protected static List<Customer> Customers;
    public List<Customer> GetReport(string Name,string Surname,string Address,string Phone) {
        //NHibernate üzerinden select
        Customers = new List<Customer>();

        using (var session = NHibernateHelper.OpenSession())
        {
            using (var transaction = session.BeginTransaction())
            {
                var results = from c in session.Query<Customer>()
                              select c;
                foreach (var result in results)
                {
                    Customer customer = new Customer
                    {
                        CustomerId = result.CustomerId,
                        Name = result.Name,
                        Surname = result.Surname,
                        Address = result.Address,
                        Phone = result.Phone
                    };

                    Customers.Add(customer);
                }

                if (Customers.Count>0)
                {
                    return Customers;
                }
                else
                {
                    return null;
                }
            }
        }
    }

MVC代码：

ServiceReport.ReportServiceClient service = new ServiceReport.ReportServiceClient();

List<Customer> list = new List<Customer>();
list = service.GetReport(Name, Surname, Address, Phone);
