無法在ASP.NET Core 2.0中創建遷移

Question

我正在嘗試創建身份遷移是ASP.NET Core 2.0，並且出現錯誤。

System.Data.SqlClient.SqlException（0x80131904）：無法打開登錄請求的數據庫“ MarketIdentity”。 登錄失敗。

Appsettings.json

"MarketIdentity": {
  "ConnectionString": "Server=(localdb)\\mssqllocaldb;Database=MarketIdentity;Trusted_Connection=True;MultipleActiveResultSets=true"
}

startup.cs

public void ConfigureServices(IServiceCollection services)
    {
        //services.Configure<AppSettings>(Configuration.GetSection("Data:Market"));

        services.AddMvc();

        //app database
        services.AddDbContext<EfDbContext>(
            options => options.UseSqlServer(Configuration["Data:Market:ConnectionString"],
            b => b.MigrationsAssembly("Market")));

        //identity database
        services.AddDbContext<AppIdentityDbContext>(
            options => options.UseSqlServer(Configuration["Data:MarketIdentity:ConnectionString"],
            b => b.MigrationsAssembly("Market")));

        services.AddIdentity<IdentityUser, IdentityRole>(options => {
            options.Password.RequireNonAlphanumeric = false;
            options.Password.RequireUppercase = false;
            options.Password.RequireLowercase = false;
            options.Password.RequireDigit = false;
        })
            .AddEntityFrameworkStores<AppIdentityDbContext>();
    }

嘗試這個

"ConnectionStrings": {
    "MarkIdentity": "Server=(localdb)\\mssqllocaldb;Database=MarketIdentity;Trusted_Connection=True;MultipleActiveResultSets=true"
}

services.AddDbContext<EfDbContext>(options =>
    options.UseSqlServer(Configuration.GetConnectionString("MarkIdentity")));
