实体框架+ Fluent轻量级配置仅适用于实体类型

Question

I am trying to configure table names in model so that each table belongs to schema named by containing namespace with this code:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    if (modelBuilder == null) throw new ArgumentNullException(nameof(modelBuilder));

    foreach (var creator in ModelCreators)
    {
        creator.OnModelCreating(modelBuilder);
    }
    modelBuilder.Types().Configure(c => c.ToTable(PrefixNamespace(c.ClrType)));
}

private string PrefixNamespace(Type type)
{
    var result = $"{type.Namespace.Split('.').Last()}.{type.Name}";
    return result;
}

The problem is that applying this configuration affects ComplexTypes as well, which are then configured as entities. How to apply this configuration to entities only? The modelBuilder.Entity<TEntity>(TEntity entity) can configure only one entity at the time, but not all entity types are known during build time, some will be discovered from .dlls.

I was thinking about something like

modelBuilder.Types().Where(t => IsNotComplexType(t)).Configure(...)

but I don't know how to implement IsNotComplexType form available objects.

我得出的结论是，必须通过DbModelBuilder.ComplexType<TComplexType>()显式设置复杂类型，因此在应用ToTable(string tableName)方法后，它不会变成实体。
