我正在跟随一个制作dotnet 2 rest api的教程，并期望dotnet cli在dotnet ef update之后生成数据库。但是这并没有发生。
我有这个上下文类
public class DutchContext : DbContext
{
public DutchContext(DbContextOptions<DutchContext> options): base(options)
{
public DbSet<Product> Products { get; set; }
public DbSet<Order> Orders { get; set; }
}
}
这是我在 StartUp.cs 中调用 con 字符串的方式。
public void ConfigureServices(IServiceCollection services)
{
services.AddTransient<IMailService, NullMailService>();
// support for real mail service
services.AddMvc();
services.AddDbContext<DutchContext>(cfg =>
{
cfg.UseSqlServer(_config.GetConnectionString("ConnectionString"));
});
}
还有保存 con 字符串的 config.json 文件
{
"ConnectionStrings": {
"ConnectionString": "Server=(localdb)\\MSSQLLocalDB;Database=EstudoDotnetDB;Integrated Security=true;MultipleActiveResultSets=true"
}
}
这是我的本地数据库名称 > (localdb)\MSSQLLocalDB
终端输出如下
$ dotnet ef database update

No migrations were applied. The database is already up to date.

Done.
有什么想法吗？
如果这是一个愚蠢的问题，很抱歉，我对dotnet 2还不熟悉。
