Selecting certain properties of a DF/EF object.

   How can I select certain properties to return without creating a new anonymous object? My goal is to use the Employee object I would normally get back but only fill certain properties in an effort to reduce the data going across my WCF service. Is this possible? With this code I get this error where I set Employee=item within my foreach loop.

Cannot implicitly convert type 'AnonymousType#1' to 'AmberStream.Model.Payroll.Employee'

            var query = _entityManager
                .Employees
                .AddIncludePaths("Person")
                .Where(col => col.Employee_ID == id)
                .Select(e => new { e.Employee_ID, e.Person.FirstName, e.Person.LastName })
                .ExecuteAsync(op => {
                    if (op.HasError)
                        throw op.Error;

                    foreach (var item in op.Results)
                    {
                        Employee = item; 
                    }

                    // debugging log
                    ObjectDumper.Write(Employee);
                    ObjectDumper.Write(Employee.Person.FirstName);
                    ObjectDumper.Write(Employee.Person.LastName);
                });
