How to omit XmlTypeAttributes from List<T> class Properties? xsi:t

[Samuel]

All,

I am at wits end with this one. Spent hours going through MSDN and online
articles to try to resolve this.

XmlSerializer is including the “xsi:type� attribute when I serialize a
property that is a List<Tof derived objects.

How do I stop this from happening?
Constraints:
XmlIncludeAttributes are unfeasible as bases classes are in separate
assemblies and know nothing of the specializations.
The context is not a web service. Just trying to get a text stream of the
serialized object using the XmlSerializer.

Thanks for all of your help.

[XmlRootAttribute(“Lot�, Namespace=�http://tempuri.org�)]
public class Car
{
}

[XmlRootAttribute(“Lot�, Namespace=�http://tempuri.org�)]
public class HotRod: Car
{
}
[XmlRootAttribute(“Lot�, Namespace=�http://tempuri.org�)]
public class Wagon: Car
{
}

[XmlRootAttribute(“Lot�, Namespace=�http://tempuri.org�)]
public class ParkingLot: Lot
{

[XmlArrayAttribute(“Cars�, Namespace=�http://tempuri.org�)]
[XmlArrayItemAttribute(“Car�, Namespace=�http://tempuri.org�)]
public List<CarCars {get; set}

}

ParkingLot should serialize like this:
<Lot xmlns=�http://tempuri.org�>
<Cars>
<Car></Car>
<Car></Car>
</Cars>
</Lot>

Reality Check
Instead, I get this:
This is a bit frustrating . . . . I have tried using
XmlAttributeOverrides, XmlTypeAttributes, etc etc.
Anyone know how to do this?

ParkingLot serializes like this instead:
<Lot xmlns=http://tempuri.org xmlns:xsi=�theXmlSchema-instance namespace�>
<Cars>
<Car xsi:Type=�HotRod�></Car>
<Car xsi:Type=�Wagon�></Car>
</Cars>
</Lot>
