System.InvalidOperationException: Type is not supported

[jsmcneal]

Simple enough:

MasterMessageModel masterMessage = ZeroFormatter.ZeroFormatterSerializer.Deserialize<MasterMessageModel>(trssFrame.ToByteArray());

My Model
[ZeroFormattable] public class MasterMessageModel : MessageBase { [Index(2)] public virtual Guid PlanKey { get; set; } = Guid.Empty; [Index(3)] public virtual Guid DeviceKey { get; set; } = Guid.Empty; [Index(6)] public virtual int DeviceID {get; set;} [Index(7)] public virtual int ModeOfTransport { get; set; } = 0; [Index(8)] public virtual DateTime MonitorTime { get; set; } [Index(9)] public virtual DateTime SensorTime { get; set; } [Index(10)] public virtual string MessageType { get; set; } = string.Empty; [Index(11)] public virtual int Sequence { get; set; } [Index(12)] public virtual string Details { get; set; } = string.Empty; [Index(13)] public virtual bool Acknowledged { get; set; } = true; [Index(14)] public virtual string Encryption { get; set; } = string.Empty; [Index(15)] public virtual string Authentication { get; set; } = string.Empty; [Index(16)] public virtual string Spoof { get; set; } = string.Empty; [Index(17)] public virtual int ReceiveChannel { get; set; }
}

This is what gets thrown:

Exception thrown: 'System.InvalidOperationException' in Alexinea.ZeroFormatter.dll

Why is the Type not supported on an innocuous model?
