Protobuf-net InvalidProgramException on first time serialization

Im started a small project, to test protobuf functionality with unity. I tried to serialize some polymorphic values from different buttons click. When I start project, I always have an InvalidProgramException at first button-click. But all subsequent clicks don't cause that exception.

I'm tried to google that, but found nothing.

Full error syntax are:

InvalidProgramException: Invalid IL code in (wrapper dynamic-method) object:proto_3 (object,ProtoBuf.ProtoWriter): IL_0025: box       0x00000007

This is some code, that I'm using for:

[ProtoContract(SkipConstructor = true)]    
public struct NetworkCommandSerializationWrapper
{
    [ProtoMember(1)]
    public IActorNetworkCommand Command;
}

[ProtoContract]
[ProtoInclude(10, typeof(RendererStateNetworkCommand))]
[ProtoInclude(20, typeof(RD2))]
public interface IActorNetworkCommand
{
    void Execute();
}

[ProtoContract]
public struct RendererStateNetworkCommand : IActorNetworkCommand
{
    public RendererStateNetworkCommand(RendererStateNetworkData i)
    {
        data = i;
    }

    public void Execute()
    {    
    }

    [ProtoMember(11)]
    public RendererStateNetworkData data;
}

public struct RD2 : IActorNetworkCommand
{
    public void Execute()
    {
    }

    [ProtoMember(21)]
    public int data3;
}

public interface ISerializator<TResult>
{
    TResult SerializeObject<T>(T serializableObject);
    T DeserializeObject<T>(TResult serilizedBytes);
}

public class BinarySerializator : ISerializator<byte[]>
{
    public byte[] SerializeObject<T>(T serializableObject)
    {
        Debug.LogFormat("SerializeObject {0}, {1}", serializableObject, serializableObject.GetType());

        using (MemoryStream mStream = new MemoryStream())
        {
            Serializer.Serialize<T>(mStream, serializableObject);
            return mStream.ToArray();
        }
    }
    public T DeserializeObject<T>(byte[] serilizedBytes)
    {
        using (MemoryStream mStream = new MemoryStream(serilizedBytes))
        {
            return Serializer.Deserialize<T>(mStream);
        }
    }
}

public abstract class ButtonContextBase : MonoBehaviour, IButtonContext
{
    public virtual void OnButtonClick()
    {
        ClickHandler.Instance.OnClick(SerializeData(GetCommand()));        
    }

    protected abstract IActorNetworkCommand GetCommand();

    protected byte[] SerializeData(IActorNetworkCommand command)
    {
        if (command == null)
        {
            Debug.LogErrorFormat("Command is null!");
            return null;
        }

        var wrapper = new NetworkCommandSerializationWrapper() { Command = command };
        Debug.LogFormat("SerializeData {0}, {1}", command, wrapper.Command);
        var data = SerializatorSingletone.Instance.SerializeObject(wrapper);

        return data;
    }
}

public class RendererStateContext : ButtonContextBase
{
    protected override IActorNetworkCommand GetCommand()
    {
        var command = new RendererStateNetworkCommand() { data = new RendererStateNetworkData() { sh_State = (ushort)ERendererState.Idle } };
        return command;
    }
}

public class SerializatorSingletone : MonoBehaviour
{
    private static BinarySerializator m_Instance;

    public static BinarySerializator Instance
    {
        get
        {
            if (m_Instance == null)
            {
                m_Instance = new BinarySerializator();
            }

            return m_Instance;
        }
    }
}
