asp.net - 带有 PostgreSql 的 ASP Core 1。授权和认证

Question

我有一个基于 ASP Core 1 的 Web 应用程序，带有 PostgreSql 数据存储。现在我想添加身份验证功能。我已经创建了具有授权的基本示例 mvc 项目，它可以很好地与 MsSql 服务器一起工作。但是 PostgreSql 呢？

首先我创建了具有相同模式的数据库(sql 是通过 dnx ef migrations script 生成的，代码是用 pg 风格更新的)。然后我用 Postgres 配置了 EF

services.AddEntityFramework()
    .AddNpgsql()
    .AddDbContext<ApplicationDbContext>(options =>
        options.UseNpgsql(Configuration["Data:DefaultConnection:ConnectionString"]));

当我尝试注册为新用户时，出现错误 42P01: relation\"AspNetUsers\"does not exist。我已经用双引号将表名括起来，但这没有帮助。我无权访问默认身份验证模型，也无法将名称属性添加到表名称和字段名称。

所以，我的问题是:

1. 我的示例项目有什么问题，为什么我无法访问数据库？

2. 更全局化。使用 ASP Core 1 + PostgreSql 组织授权和身份验证的最佳方式是什么？我不需要所有 ASP 身份验证功能，我只需要角色，我想要基于 bigint 的 ID 并且我想要扩展用户模型(表)。

注意:我使用 EF7。

Answer 1

所以我第一个问题的答案是错误的数据库模式。对于对模式感兴趣的人，我得到了完整的 pg sql 代码，但我的第二个问题仍然未解决。
