C# EF Scaffold DbContext反向工程表-生成无效列名错误

VS2019，核心3.1，C#

我从现有数据库反向迁移了一个表：

Scaffold DbContext“我的连接字符串”Microsoft.EntityFrameworkCore.SqlServer-OutputDir Models-Tables“Accounts”

其中一列是AcctSN（varchar（50），null）。它的生成如下所示：

publicstringacctsn{get；set；}

看不出这有什么问题。（它不是键，上面没有索引。）

我把一切都连接好了，当我打电话的时候

var accounts=await dbContext.Account.ToListAsync（）

我得到以下错误：

“无效的列名'AcctSN'。”

下面是整个错误：

这是一个独立的表。它与其他表没有关系。（我没有生成此数据库。）没有外键。该类具有另一个字符串属性，该属性成功链接到数据库中的varchar列；当我注释掉此AcctSN字段时，该属性起作用

任何想法。到目前为止，我发现的所有内容都涉及到密钥和关系的问题，但正如我上面所述，这不适用于这种情况。
您在每种情况下都使用相同的连接字符串吗？是的。我看到另一篇帖子，海报不是这样，所以我检查了。当您将属性的名称更改为完全不同的名称时，它仍然错误吗？您的意思是使用数据注释吗？我已经尝试了
[Column（“AcctSN”）]公共字符串AccountShortName{get；set；}
尝试重命名数据库中的列，然后再次scaffold。如果成功，它会告诉您te“AcctSN”作为一个名称是一个问题。如果不成功，则说明您的列有问题。在这两种情况下，如果您可以在另一个项目中重现该问题，您可以在GitHub上向EFCore团队提交一个错误。
