没有为“Microsoft.AspNetCore.Mvc.ViewFeatures.ITempDataDictionaryFactory”类型服务注册

我遇到此问题：没有为'Microsoft.AspNetCore.Mvc.ViewFeatures.ITempDataDictionaryFactory'类型注册服务。在asp.net核心1.0中，似乎当动作尝试渲染视图时，我有这种异常。没有为“Microsoft.AspNetCore.Mvc.ViewFeatures.ITempDataDictionaryFactory”类型服务注册

我搜索了很多，但我没有找到解决方案，如果有人可以帮助我弄清楚发生了什么，我该如何解决它，我将不胜感激。

这是发生在特定页面吗？你想在那个网页上做什么？当你注释掉IRestaurantData注册时，你是否能够复制这个问题？ – Shyju

@Shyju，感谢您的重播，这只是当我尝试调用View（）方法在我的homeController的任何操作中显示视图时发生，总是我不重载该方法它总是抛出异常，当我评论'IRestaurantData'注册服务的问题仍在发生，这是很奇怪的问题:(因为它似乎我缺少一些命名空间orsomething但vs不显示我在代码中的任何错误 –

@Shyju这是命名空间我“M使用： '使用Microsoft.AspNetCore.Mvc;'' 使用OdeToFood.ViewModels;'' 使用OdeToFood.Services;'' 使用OdeToFood.Entities;' –

解决方案：使用AddMvc()代替AddMvcCore()在Startup.cs，它会工作。

请看到这个问题了，为什么更多的信息：

对于大多数用户不会有任何改变，你应该继续在你的启动代码中使用 AddMvc（）和UseMvc（...）。

为了真正的勇敢，现在有一个配置体验，您可以从最小的MVC流水线开始，并添加功能来获得定制框架。

您可能还需要参考在project.json

添加到Microsoft.AspNetCore.Mvc.ViewFeature只需添加以下代码，它应该工作：

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

     }

佛[R那些.NetCore 1.X期间得到这个问题 - > 2.0的升级，同时更新您的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然后用services.AddMvcCore().AddRazorViewEngine();您ConfigureServices

还记得加.AddAuthorization()如果您使用Authorize属性，否则它将不起作用。
