.NET XML Serialization and inheritance

Question

I have structure like this:

public interface A
{
    public void method();
}

public class B : A
{
}

public class C : A
{
}

List list;

Answer 1

XmlSerializer does not work with interfaces. So you can:

Convert interface to abstract class and then use XmlIncludeAttribute for it or provide KnownTypes to XmlSerializer

or

Implement IXmlSerializable for the parent type

or

Consider using DataContractSerializer from .NET 3.0
