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));

} [/code] 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.Lazy1[Ecng.Collections.CachedSynchronizedOrderedDictionary2[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?
