SerializerGenerator can't resolve nested serializer dependency

[neuecc]

I've used SerializerGenerator.GenerateCode for avoid Unity's dynamic code generate.
But generated code seems can't avoid dynamic code generate when class is nested.

For example class A has property of class B.

public class A
{
    public B NestProperty { get; set; }
}

public class B
{
    public int Property { get; set; }
}

It generates there code.

[System.CodeDom.Compiler.GeneratedCodeAttribute("MsgPack.Serialization.CodeDomSerializers.CodeDomSerializerBuilder", "0.6.0.0")]
[System.Diagnostics.DebuggerNonUserCodeAttribute()]
public class A_Serializer : MsgPack.Serialization.MessagePackSerializer<A> {

    private MsgPack.Serialization.MessagePackSerializer<B> _serializer0;

    public A_Serializer(MsgPack.Serialization.SerializationContext context) : 
            base(context) {
        MsgPack.Serialization.PolymorphismSchema schema0 = default(MsgPack.Serialization.PolymorphismSchema);
        schema0 = null;
        this._serializer0 = context.GetSerializer<B>(schema0);
    }

    // snip...
}

[System.CodeDom.Compiler.GeneratedCodeAttribute("MsgPack.Serialization.CodeDomSerializers.CodeDomSerializerBuilder", "0.6.0.0")]
[System.Diagnostics.DebuggerNonUserCodeAttribute()]
public class B_Serializer : MsgPack.Serialization.MessagePackSerializer<B> {

    private MsgPack.Serialization.MessagePackSerializer<int> _serializer0;

    public B_Serializer(MsgPack.Serialization.SerializationContext context) : 
            base(context) {
        MsgPack.Serialization.PolymorphismSchema schema0 = default(MsgPack.Serialization.PolymorphismSchema);
        schema0 = null;
        this._serializer0 = context.GetSerializer<int>(schema0);
    }

    // snip...
}

I generate there serializer helper code, too.

public static class MsgPackSerializer
{
    static readonly SerializationContext serializationContext = new SerializationContext
    {
        EnumSerializationMethod = EnumSerializationMethod.ByUnderlyingValue,
        GeneratorOption = SerializationMethodGeneratorOption.Fast,
        SerializationMethod = SerializationMethod.Array
    };

    static MsgPackSerializer()
    {
        serializationContext.Serializers.Register(new A_Serializer(serializationContext));
        serializationContext.Serializers.Register(new B_Serializer(serializationContext));
    }

    public static byte[] Pack<T>(T obj)
    {
        return serializationContext.GetSerializer<T>().PackSingleObject(obj);
    }

    public static T Unpack<T>(byte[] obj)
    {
        return serializationContext.GetSerializer<T>().UnpackSingleObject(obj);
    }
}

If call Serializers.Register(new A_Serializer()) before Serializers.Register(new B_Serializer()), A_Serializer runs
this._serializer0 = context.GetSerializer<B>(schema0); but B_Serializer is not registered yet, so B_Serializer was generated by dynamic code generation.
This is very inconvenient.
In Unity, must avoid dynamic code generation.

Please solve this problem.

Added new SerializationContext.ResolveSerializer event in 0.6.0.
