CUD 方法不会触发

Question

我正在尝试将 RIA 服务与存储库模式一起使用，每个 CRUD 操作都完美运行，直到我实现存储库。现在只有查询和提交方法有效。我尝试了带有和不带有查询、插入、更新和删除属性的方法。

有人知道问题是什么吗？

[LinqToEntitiesDomainServiceDescriptionProvider(typeof(MyEntityModelContainer))]
[EnableClientAccess()]
public class MyService : DomainService
{
    internal IUnitOfWork ObjectContext { get; private set; }

    public MyService(IUnitOfWork context)
    {
        this.ObjectContext = context;
    }

    public IQueryable<Employee> GetEmployees()
    {
        return this.ObjectContext.BusinessEntities.OfType<Employee>();
    }

    public void InsertEmployee(Employee employee)
    {
        this.ObjectContext.BusinessEntities.AddObject(employee);
    }

    public void UpdateEmployee(Employee currentEmployee)
    {
        this.ObjectContext.BusinessEntities.AttachAsModified(currentEmployee,     this.ChangeSet.GetOriginal(currentEmployee));
    }

    public void DeleteEmployee(Employee employee)
    {
        if( (employee.EntityState == EntityState.Detached) )
        {
            this.ObjectContext.BusinessEntities.Attach(employee);
        }

        this.ObjectContext.BusinessEntities.DeleteObject(employee);
    }

    public override bool Submit(ChangeSet changeSet)
    {
        this.ObjectContext.Commit();
        return true;
    }
}

我错误地覆盖了 Submit 方法。
