问题
I'm having this problem: No service for type 'Microsoft.AspNetCore.Mvc.ViewFeatures.ITempDataDictionaryFactory' has been registered. In asp.net core 1.0, it seems that when the action try to render the view i have that exception.
I've searched a lot but I dont found a solution to this, if somebody can help me to figure out what's happening and how can I fix it, i will appreciate it.
My code bellow:
My project.json file
{
"dependencies": {
"Microsoft.NETCore.App": {
"version": "1.0.0",
"type": "platform"
},

},
"tools": {
"Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final"
},
"frameworks": {
"netcoreapp1.0": {

}
},

}
},

"wwwroot",
"web.config"
]
},
"scripts": {
"postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
}
}
My Startup.cs file
using System;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Routing;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using OdeToFood.Services;
namespace OdeToFood
{
public class Startup
{
public IConfiguration configuration { get; set; }
// This method gets called by the runtime. Use this method to add services to the container.
// For more information on how to configure your application, visit http://go.microsoft.com/fwlink/?LinkID=398940
public void ConfigureServices(IServiceCollection services)
{
services.AddScoped<IRestaurantData, InMemoryRestaurantData>();
services.AddMvcCore();
services.AddSingleton(provider => configuration);
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
//app.UseRuntimeInfoPage();
app.UseFileServer();
app.UseMvc(ConfigureRoutes);
app.Run(async (context) =>
{
await context.Response.WriteAsync("Hello World!");
});
}
private void ConfigureRoutes(IRouteBuilder routeBuilder)
{
routeBuilder.MapRoute("Default", "{controller=Home}/{action=Index}/{id?}");
}
}
}

Solution: Use AddMvc() instead of AddMvcCore() in Startup.cs and it will work.
Please see this issue for further information about why:
For most users there will be no change, and you should continue to use AddMvc() and UseMvc(...) in your startup code.
For the truly brave, there's now a configuration experience where you can start with a minimal MVC pipeline and add features to get a customized framework.

You might also have to add a reference
toMicrosoft.AspNetCore.Mvc.ViewFeature in project.json
https://www.nuget.org/packages/Microsoft.AspNetCore.Mvc.ViewFeatures/
回答2:
If you're using 2.0 then use services.AddMvcCore().AddRazorViewEngine(); in your ConfigureServices
Also remember to add .AddAuthorization() if you're using Authorize attribute, otherwise it won't work.

I know this is an old post but it was my top Google result when running into this after migrating an MVC project to .NET Core 3.0. Making my Startup.cs look like this fixed it for me:
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddControllersWithViews();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseRouting();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
}
回答4:
For .NET Core 2.0, in ConfigureServices, use :
services.AddNodeServices();
回答5:
Just add following code and it should work:
public void ConfigureServices(IServiceCollection services)
{
services.AddMvcCore()
.AddViews();
}
回答6:
For those that get this issue during .NetCore 1.X -> 2.0 upgrade, update both your Program.cs and 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
}
}
回答7:
This one works for my case :
services.AddMvcCore()
.AddApiExplorer();
回答8:
You use this in startup.cs
services.AddSingleton<PartialViewResultExecutor>();
回答9:
To be able to return JSON data, JsonFormatterServices need to be registered with the dependency injection container. AddMvc() method does this but not the AddMvcCore() method. You can confirm this by looking at the source code on ASP.NET Core MVC Github page.
