<DataContract()>
Public Class Employee
  Implements IKnownType
 
  <DataMember()>
  Public Property UserId As Integer
  <DataMember()>
  Public Property FirstName As String

End Class
'From my viewmodel
Dim q2 = _mgr.EmployeeYearbooks.Select(Function(emp) New Employee With {
                                             .UserId = emp.UserId,
                                             .FirstName = emp.EmployeesOMD.FirstName}
                                             )
 
    q2.ExecuteAsync(Sub(e) e.Results.ForEach(Sub(ee) Employees.Add(ee)))

But when I add one property it stops working, any thoughts?

This doesn't work.
