Does not support array for WCF

[GoogleCodeExporter]

Protobuf does not support a simple array, but List<T> supported without any 
problems.

What steps will reproduce the problem?
1. implement service with method Foo[] GetFoos() marked by [OperationContract, 
ProtoBehavior] (which return some stuff data)
2. enable WCF service logging and call method from client proxy
3. see WCF logs

Is it possible to add support a array?

Another issue:
I did not see support inheritance in protobuf for DTO?

for example:
    [DataContract]
    public class DataObjectBase
    {
        [DataMember(Order = 1)]
        public string Name { get; set; }
    }

    [DataContract]
    public class DataObject : DataObjectBase
    {
        [DataMember(Order = 2)]
        public int Number { get; set; }
    }

DataObject.Name always is 'null' at client side. [KnownType] did not help.

OS: Win7 .NET 3.5 sp1
protobuf.net: lastest sources from svn built on Release.

I'll investigate the array thing. Inheritance is via ProtoIncludeAttribute, or 
MetaType.AddSubType (to define at runtime)

I am also having an issue serializing arrays. The following line of code fails 
if data is string[]

runtimeTypeModel.Serialize(stream, data);

(runtimeTypeModel is of type RuntimeTypeModel)

The exception message is: "Repeated data (a list, collection, etc) has inbuilt 
behaviour and cannot be used as a subclass", 

Stack trace:

I am also have an issue when I use protobuf-net as serializer for WCF via 
extension.
Arrays cannot be serialized via protobuf-net.

ProtoOperationBehavior new serializer tries to be created like this:

var model = RuntimeTypeModel.Default;
var serializer = XmlProtoSerializer.TryCreate( model, typeof( Int32[] ) );
Assert.IsNotNull( serializer );

var serializer0 = XmlProtoSerializer.TryCreate( model, typeof( String[] ) );
Assert.IsNotNull( serializer0 );

Both assertion won't pass.

The probem is also with 

var serializerList0 = XmlProtoSerializer.TryCreate( model, typeof( List<String> 
) );
Assert.IsNotNull( serializerList0 );

If introduce some DTO:

    [ProtoContract]
    [DataContract]
    public class Dto
    {
        [DataMember]
        [ProtoMember( 1 )]
        private Int32 id;

        public Int32 Id
        {
            get
            {
                return id;
            }
            set
            {
                id = value;
            }
        }

        public Dto()
        {

        }
    }

will be OK:

var serializerList = XmlProtoSerializer.TryCreate( model, typeof( List<Dto> ) );
Assert.IsNotNull( serializerList );

var serializer1 = XmlProtoSerializer.TryCreate( model, typeof( Dto ) );
Assert.IsNotNull( serializer1 );

Won't be passed:

var serializer2 = XmlProtoSerializer.TryCreate( model, typeof( Dto[] ) );
// Cannot find serializer for array
Assert.IsNotNull( serializer2 );

Noticed the same this. The behavior doesn't recognize the array of a registered 
type. Saw this posting that may be of help:
