c# - mono の DataContractSerializer が奇妙なエラーを返す

Question

データをシリアル化するための単純なデータシリアライザーを作成しました。データをシリアル化および逆シリアル化するための非常に簡単な方法があります。それを行うには2つの方法があります。

public string Serialize()
    {
        SerializedData data = new SerializedData(this);
        DataContractSerializer serializer = new DataContractSerializer(typeof(SerializedData));
        System.IO.MemoryStream s = new System.IO.MemoryStream();
        serializer.WriteObject(s, data);
        return Convert.ToBase64String(s.ToArray());
    }

    public static MessageBlock Deserialize(string name, string sdata, Map map)
    {
        byte[] bdata = Convert.FromBase64String(sdata);
        MessageBlock MessageBlock = new MessageBlock();
        DataContractSerializer serializer = new DataContractSerializer(typeof(SerializedData));
        System.IO.MemoryStream s = new System.IO.MemoryStream(bdata);
        SerializedData data = (SerializedData)serializer.ReadObject(s);

        data.UpdateMessageBlock(MessageBlock);
        return MessageBlock;
    }
    [DataContract]
    private class SerializedData
    {
        [DataMember]
        public String Name;
        [DataMember]
        public String Creator;
        [DataMember]
        public DateTime Created;
        [DataMember]
        public String World;
        [DataMember]
        public Vector3I AffectedBlock;
        [DataMember]
        public int XMin;
        [DataMember]
        public int XMax;
        [DataMember]
        public int YMin;
        [DataMember]
        public int YMax;
        [DataMember]
        public int ZMin;
        [DataMember]
        public int ZMax;
        [DataMember]
        public String Message;

        public SerializedData(MessageBlock MessageBlock)
        {
            lock (MessageBlock)
            {
                Name = MessageBlock.Name;
                Creator = MessageBlock.Creator;
                Created = MessageBlock.Created;
                World = MessageBlock.World;
                AffectedBlock = MessageBlock.AffectedBlock;
                XMin = MessageBlock.Range.Xmin;
                XMax = MessageBlock.Range.Xmax;
                YMin = MessageBlock.Range.Ymin;
                YMax = MessageBlock.Range.Ymax;
                ZMin = MessageBlock.Range.Zmin;
                ZMax = MessageBlock.Range.Zmax;
                Message = MessageBlock.Message;
            }
        }

        public void UpdateMessageBlock(MessageBlock MessageBlock)
        {
            MessageBlock.Name = Name;
            MessageBlock.Creator = Creator;
            MessageBlock.Created = Created;
            MessageBlock.World = World;
            MessageBlock.AffectedBlock = AffectedBlock;
            MessageBlock.Range = new MessageBlockRange(XMin, XMax, YMin, YMax, ZMin, ZMax);
            MessageBlock.Message = Message;
        }
    }

コードを実行しているサーバーは mono 3.2.1 を使用した ubuntu です。Windows では問題ありません。Windows NET 4 ではエラーなく簡単にコードを実行できます。しかし、mono は DataContractSerializer をサポートしていないようです。mono でエラーが発生しました。は：
