当重写一个抽象方法并尝试调用我目前正在覆盖的基类方法时,我发现了一个非常奇怪的问题.

//In Dll "A"
namespace Rhino.Etl.Core.Operations

    using System.Collections;
    using System.Collections.Generic;

    public class Row {}

    public interface IOperation
    {

    }

    public abstract class AbstractDatabaseOperation : AbstractOperation
    {
    }

    public abstract class SqlBulkInsertOperation : AbstractDatabaseOperation
    {
        public override IEnumerable<Row> Execute(IEnumerable<Row> rows)
        {
            Console.WriteLine("SqlBulkInsertOperation");
            return rows;
        }
    }
}

//In console app "B"

    using System;
