int[50000]

Protobuf-net 3.0.0-alpha.34 / MessagePack 2.0.335 / Apex

Serializing/deserializing the object defined as follows

        [ProtoContract]
        [MessagePackObject]
        public class Wrapper
        {
            [ProtoMember(1)]
            [Key(0)]
            public int[] _t1 = new int[50000];
        }

The first element of the int[] is returned from the test method after deserializing.
