沒有爲「Microsoft.AspNetCore.Mvc.ViewFeatures.ITempDataDictionaryFactory」類型服務註冊

我遇到此問題：沒有爲'Microsoft.AspNetCore.Mvc.ViewFeatures.ITempDataDictionaryFactory'類型註冊服務。在asp.net核心1.0中，似乎當動作嘗試渲染視圖時，我有這種異常。沒有爲「Microsoft.AspNetCore.Mvc.ViewFeatures.ITempDataDictionaryFactory」類型服務註冊

我搜索了很多，但我沒有找到解決方案，如果有人可以幫助我弄清楚發生了什麼，我該如何解決它，我將不勝感激。

我的代碼波紋管：

這是發生在特定頁面嗎？你想在那個網頁上做什麼？當你註釋掉IRestaurantData註冊時，你是否能夠複製這個問題？ – Shyju

@Shyju，感謝您的重播，這只是當我嘗試調用View（）方法在我的homeController的任何操作中顯示視圖時發生，總是我不重載該方法它總是拋出異常，當我評論'IRestaurantData'註冊服務的問題仍在發生，這是很奇怪的問題:(因爲它似乎我缺少一些命名空間orsomething但vs不顯示我在代碼中的任何錯誤 –

@Shyju這是命名空間我「M使用： '使用Microsoft.AspNetCore.Mvc;'' 使用OdeToFood.ViewModels;'' 使用OdeToFood.Services;'' 使用OdeToFood.Entities;' –

解決方案：使用AddMvc()代替AddMvcCore()在Startup.cs，它會工作。

請看到這個問題了，爲什麼更多的信息：

對於大多數用戶不會有任何改變，你應該繼續在你的啓動代碼中使用 AddMvc（）和UseMvc（...）。

爲了真正的勇敢，現在有一個配置體驗，您可以從最小的MVC流水線開始，並添加功能來獲得定製框架。

您可能還需要參考在project.json

添加到Microsoft.AspNetCore.Mvc.ViewFeature只需添加以下代碼，它應該工作：

public void ConfigureServices(IServiceCollection services) 
     { 
      services.AddMvcCore() 
        .AddViews(); 

     }

佛[R那些.NetCore 1.X期間得到這個問題 - > 2.0的升級，同時更新您的Program.cs和Startup.cs

public class Program 
{ 
    public static void Main(string[] args) 
    { 
     BuildWebHost(args).Run(); 
    } 

    public static IWebHost BuildWebHost(string[] args) => 
     WebHost.CreateDefaultBuilder(args) 
      .UseStartup<Startup>() 
      .Build(); 
} 

public class Startup 
{ 
// The appsettings.json settings that get passed in as Configuration depends on 
// project properties->Debug-->Enviroment Variables-->ASPNETCORE_ENVIRONMENT 
    public Startup(IConfiguration configuration) 
    { 
     Configuration = configuration; 
    } 

    public IConfiguration Configuration { get; } 

    public void ConfigureServices(IServiceCollection services) 
    { 
     services.AddDbContext<ApplicationDbContext>(options => 
      options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"))); 

     services.AddIdentity<ApplicationUser, IdentityRole>() 
      .AddEntityFrameworkStores<ApplicationDbContext>() 
      .AddDefaultTokenProviders(); 

     services.AddTransient<IEmailSender, EmailSender>(); 

     services.AddMvc(); 
    } 

    public void Configure(IApplicationBuilder app, IHostingEnvironment env) 
    { 
    // no change to this method leave yours how it is 
    } 
}

如果您使用2.0然後用services.AddMvcCore().AddRazorViewEngine();您ConfigureServices

還記得加.AddAuthorization()如果您使用Authorize屬性，否則它將不起作用。
