【ASP.NET Core快速入门】（十三）Individual authentication 模板、EF Core Migration

Individual authentication 模板

我们首先用VSCode新建一个mvc的网站，这个网站创立的时候回自动为我们创建Identuty Core以及EF Core的代码示例，我们可以用命令 dotnet new mvc --help 来查看一些参数：

由于我们创建mvc项目是默认不带Identity验证的，所以我们要加上下面的 -au|--auth 参数来使用Individual创建带Identity验证的网站

还有一个参数 -uld|--use-local-db 参数来使用本地数据库，在VSCode默认的是使用SqlLite，在VS2017中默认使用的是LocalDB。

接下来我们就可以使用以下命令创建包含Identity的mvc网站IdentitySample

dotnet new mvc -au Individual -uld --name IdentitySample

创建完成后我们打开创建的项目，然后查看appsettings.json，发现已经默认创建了数据库连接，我们可以将数据库修改成自己的数据库地址

同时我们可以打开Startup.cs可以查看数据库配置以及Identity验证已经帮我们添加好了

接下来我们初始化一下数据库，否则启动之后会报错，所以我们要使用EF Core的Migration命令来初始化数据库。

我们使用的第一个命令是 dotnet ef database update 他会根据当前migration文件夹下的文件来帮我们进行数据库的创建和更新。

我们可以在终端看到执行的sql语句
