NullReferenceException of ExtendedXmlSerializer.Deserialize()

I’m trying to Deserialize the following XML which was produced by ExtendedXmlSerializer:

<?xml version="1.0" encoding="utf-8"?>
<ArrayOfIPreflightCheck>
	<DiskSpace type="ImageMenu.PreflightChecks.DiskSpace">
		<MinimumMb>20480</MinimumMb>
		<RecommendedMb>40960</RecommendedMb>
		<DiskNumber>0</DiskNumber>
		<Name>Disk 0 Size Check</Name>
	</DiskSpace>
</ArrayOfIPreflightCheck>

Yet I immediately get a NullReferenceException.

Here’s my code:

    public class DiskSpace : IPreflightCheck
    {
                public uint MinimumMb { get; set; }
        public uint RecommendedMb { get; set; }
        public ushort DiskNumber { get; set; }

        public DiskSpace(ushort diskNumber, uint minimumMb, uint recommendedMb)
        {
            DiskNumber = diskNumber;
            MinimumMb = minimumMb;
            RecommendedMb = recommendedMb;

            Name = $"Disk {DiskNumber} Size Check";
        }

        public string Name { get; set; }

        [XmlIgnore]
        public PreflightCheckStatus Status { get; private set; }

        [XmlIgnore]
        public string Message { get; private set; } = "";

        public PreflightCheckStatus Validate()
        {
            ...
        }
    }

    public interface IPreflightCheck
    {
        string Name { get; }

        PreflightCheckStatus Status { get; }

        string Message { get; }

        PreflightCheckStatus Validate();
    }

    var diskSpace = new DiskSpace(0, 20 * 1024, 40 * 1024);
    var t = new ExtendedXmlSerializer();
    var xml = t.Serialize(diskSpace);
    var co = t.Deserialize<DiskSpace>(xml);

Any ideas what the problem might be? I’m using version 1.5

Of course if this issue will take many time in first step we can add only message “Type X doesn’t have public constructor without parameters” or something like that.

I will be closing this issue since it is captured by #8 and opening another issue for the cool Protobuf constructor serialization. Please let me know if I have something misunderstood and/or feel free to re-open this issue as well.
