Exception when trying to get serializator

[QuantumDeveloper]

Hello,
I jiust started to use your lib and faced with exception:
when I try to do this:
var serializer = SerializationContext.Default.GetSerializer<EntityDataContainer>();
I receive ArgumentException that says that element with the same key was already added.

Please, tell me what I am doing wrong here?

[QuantumDeveloper]

Any workaround for this issue?
Anybody...

[Algorithman]

Assuming you want a custom serializer, then you need to add it to a new serialization context.
Look here: https://github.com/msgpack/msgpack-cli/blob/master/samples/Samples/Sample04_CustomSerializer.cs

The RegisterAndUseCustomSerializer() is the key.

Else use MessagePackSerializer.Get<EntityDataContainer>()

[QuantumDeveloper]

I created my custom packer:

public class GameObjectSerialization : MessagePackSerializer<EntityDataContainer>
    {
        public GameObjectSerialization(SerializationContext ownerContext) : base(ownerContext) { }

        protected override void PackToCore(Packer packer, EntityDataContainer objectTree)
        {
            packer.Pack(objectTree);
        }

        protected override EntityDataContainer UnpackFromCore(Unpacker unpacker)
        {
            MessagePackObject obj;
            unpacker.ReadObject(out obj);
            var b = obj.AsMessagePackExtendedTypeObject();

            return null;
        }
    }

And try to pack like this:

var context = new SerializationContext();
            context.SerializationMethod = SerializationMethod.Map;

            // 2. Register custom serializers.
            context.Serializers.RegisterOverride(new GameObjectSerialization(context));

            // 3. Get a serializer instance with customized settings.
            var serializer = MessagePackSerializer.Get<EntityDataContainer>(context);
            serializer.Pack(output, dataContainer);

I still have the same issue, but now othis line:

serializer.Pack(output, dataContainer);

Am I missing something?

[Algorithman]

Hmm, i used your source, made a small project and it runs just fine.
Do you have something special inside EntityDataContainer?
And the full Exception Message/Stacktrace could help too.

[QuantumDeveloper]

No, nothing special. Here is my stack trace:

It just looks conflict of member names to be [de]serialized. Could you expose what your EntityDataContainer is with inheritance hierarchy? I guess your class has base type member hiding.

[QuantumDeveloper]

There is no any inheritance in any of my classes inside EntityDataContainer. Its just container for dictionaries, which contain classes. Thats all.

[yfakariya]

Hmm... I will make a private build to find out what member is conflict this night (in JST). Could you try it?

[QuantumDeveloper]

Sure, just give me a link :)

[yfakariya]

@QuantumDeveloper
What platform do you use?

[QuantumDeveloper]

Win 7/8.1 - WinRT, WPF

[yfakariya]

Thank you. Try this private nupkg and show me exception message (SerializationException should be thrown instead of ArgumentException).
http://1drv.ms/1zUNKkX

[QuantumDeveloper]

Could you please explain shortly how to applay your patch?

[yfakariya]

Upgrade as nuget package as following:

1. Download Nupkg file and place it your local folder.
2. In Visual Studio, open Options and add the local folder to package repositories. See http://docs.nuget.org/docs/creating-packages/hosting-your-own-nuget-feeds
3. In Package Manager GUI, search msgpack package from the lical repository with "include
   s prereleases" checkbox.
4. Upgrade msgpack package in your project. If the package is not shown, try to uninstall existing msgpack package and reinstall patched one.

[QuantumDeveloper]

Ok. Here is new exception message:
[System.Runtime.Serialization.SerializationException] {"Some member keys are duplicated. {"Item":[SharpDX.Matrix.Item(Property),SharpDX.Matrix.Item(Property)]}"} System.Runtime.Serialization.SerializationException
