C# EF多对多配置

My DbContext似乎忽略了特定实体的fluent配置。它在

外部连接

的子查询中生成表

subcionregions

，而我在fluent配置中明确指定了表

Sql:

流畅的配置：

modelBuilder
    .Entity<Region>()
    .HasMany(t => t.SubRegions)
    .WithMany(t => t.Regions)
    .Map(m =>
        {
            m.ToTable("RegionSubRegion", "dbo");
            m.MapLeftKey("RegionId");
            m.MapRightKey("SubRegionId");
        });

它是根据惯例自己产生的。为什么不在模型和配置中使用指定的列和表名？我遗漏了什么？

在尝试调试和逐步完成单元测试之后，我发现我的单元测试是针对错误/过时的引用程序集构建的

更新引用解决了该问题
