实体框架5代码第一个无效的列名？

Question

我在这篇文章中提出了一个问题：实体框架5无效的列名？，但由于代码量很大，很难检测出问题的根源。所以，我在另一个简单的环境中复制了这个例外，希望有人帮我解决这个问题：

在这个简单的应用程序中，我使用带有2个按钮的wpf窗口，用于关闭窗口，另一个用于添加模拟

我填写代码。

简而言之，异常的消息是“无效的列名称simulation_SimulationID”。

代码下方：

Answer 1

我找到了答案here！

提示是：

物业资产管理人员被提及两次：

1：对于实体声明

public virtual IList<Echeance> echeancier { get; set; }

2：对于datagrid中的wpf数据绑定

blic IList<Echeance> ListEcheances
{
    get
    {
        return echeancier;
    }
    set
    {
        echeancier = value;
        OnPropertyChanged("ListEcheances");
    }
}

如果我删除第二个声明，它可以正常工作。
