EF 试图创建泛型类型 table (TEntity)

Question

我执行（ef-core，代码优先）'by class' 配置，从通用基础 class 开始，像这样：

public class BaseEntityConfiguration<TEntity> : IEntityTypeConfiguration<TEntity>
    where TEntity : BaseEntity
{
    public virtual void Configure(EntityTypeBuilder<TEntity> builder)
    {
        var entityName = nameof(TEntity);
        builder.ToTable(entityName);
    }
}

add-migration 运行良好，但在 update-database 上它抱怨：

Cannot use table 'TEntity' for entity type 'Couche' since it is being used for entity type 'Affaire' and potentially other entity types, but there is no linking relationship. Add a foreign key to 'Couche' on the primary key properties and pointing to the primary key on another entity typed mapped to 'TEntity'.

为什么table'TEntity'是泛型占位符TEntity？

Answer 1

nameof(TEntity) 是字符串“TEntity”。你可能应该使用

var entityName = typeof(TEntity).Name;

相反。
