System.Data.DataException:“Error parsing column 6 (Amount=0.01 - Double)”

i using dapper with sqlite
i have a model UPFlow
public class UPFlow
{
public string Id { get; set; }
public string PartnerId { get; set; }
public string TradeNo { get; set; }
public string RefundTradeNo { get; set; }
public int Service { get; set; }
public int PayWay { get; set; }
public decimal Amount { get; set; } // DECIMAL(10, 2)
public string IPAddress { get; set; }
public DateTime Time { get; set; }
}

when i read this table in .net core 2.X, i get a exception :
System.Data.DataException:“Error parsing column 6 (Amount=0.01 - Double)”
InvalidCastException: Unable to cast object of type 'System.Double' to type 'System.Int64'.

bu i read this table in .net framework 4.X, it's nothing excption.

Start by reproducing the reported Amount mapping with the UPFlow model and SQLite under .NET Core 2.x, then compare the result with .NET Framework 4.x. Confirm the failure and identify the expected decimal conversion behavior before defining a regression test; the issue is resolved when the same row materializes without the reported DataException.
