Serialize c# object using MsgPack instead of Json using MsgPack Cli

I'm trying to acheive a kind of JSON serialization using MsgPack in c# I'm using MsggPack CLI you can find on https://github.com/msgpack/msgpack-cli

According msgpack.org Documentation, serialize the model

{"model":"message"}

give in hexa

81 a5 6d 6f 64 65 6c a7 6d 65 73 73 61 67 65

but when trying to do the same in c# (certainly with a naive approach)

using MsgPack.Serialization;

public class Test
{
    public string model { get; set; }
}       

public class Program
{
    static void Main(string[] args)
    {
        Test a = new Test();
        a.model = "message";

        var requestSerializer = MessagePackSerializer.Get(a.GetType());
        MemoryStream stream = new MemoryStream();
        requestSerializer.Pack(stream, a);
        byte[] res = stream.ToArray();
    }
}

I obtain

91 a7 6d 65 73 73 61 67 65

where the 'model' name is skipped...

How to fix it ???

Finally found the easy way. According to documentation, the serialization format is by default 'array' where i need 'map'. using 

SerializationContext ctx = new SerializationContext() { SerializationMethod = SerializationMethod.Map };
...

var requestSerializer = MessagePackSerializer.Get(a.GetType(), ctx);

make the tricks.
