Exception in Ecng.Reflection.dll

Hi me again,
I encountered exception in Ecng.Reflection.dll
here is the sample code:
Code

static void Main(string[] args)
{
var path = @"C:\blabla\Storage";
var storageRegistry = new StorageRegistry
{
DefaultDrive = new LocalMarketDataDrive(path),
};
var security = new Security
{
Id = "APPL@ALL",
};

var timeFrame = TimeSpan.FromMinutes(1);
var series = new CandleSeries(typeof(TimeFrameCandle), security, timeFrame);
var storage = storageRegistry.GetCandleStorage(series);
var candles = storage.Load(new DateTime(2021, 1, 4));
}

this snippet works well in .netcoreapp but failed in .net framework4.72
It throws exception when I call GetCandleStorage()
the exception message reports " Type 'System.Lazy`1[Ecng.Collections.CachedSynchronizedOrderedDictionary`2[System.DateTime,System.DateTime]]' has '0' members with name '_state' "

For using legacy dll so I must stay in .net framework, so I wonder is this fixable?




Thanks:
