In the following examples:

public class RowData
{
    public object[] Values;
}

public class FieldData
{
    public object Value;
}

I am curious as how either protobuf-net or dotnet-protobufs would handle such classes. I am more familiar with protobuf-net, so what I actually have is:

[ProtoContract]
public class RowData
{
    [ProtoMember(1)]
    public object[] Values;
}
[ProtoContract]
public class FieldData
{
    [ProtoMember(1)]
    public object Value;
}

However I get an error saying "No suitable Default Object encoding found". Is there an easy way to treat these classes, that I am just not aware of?

To elaborate more on the use case:

This is a scaled down version of a data class used in remoting. So essentially it looks like this:

FieldData data = new FieldData();
data.Value = 8;

remoteObject.DoSomething(data);

Note: I've omitted the ISerializable implementation for simplicity, but it is as you'd expect.
