EF生成迁移脚本报错：Entity type '' has a split mapping, but it doesn't map any non-primary key property to the main store object. Keep at least one non-primary key property mapped to a column on '.
EFCore生成迁移脚本时，发生如下错误：
Entity type 'tb_Project' has a split mapping, but it doesn't map any non-primary key property to the main store object. Keep at least one non-primary key property mapped to a column on 'tb_Project'.
原因
采用了分表的方式，但模型中只有两个健，一个主键，一个描述，没有其他多余的字段了，这个时候把描述列分表的话，就会报这个错误
解决
添加一个不用于分表的非主键的列，就解决这个问题了
