我使用 ASP.NET Core + Angular 2 Visual Studio模板。我已经更新了我的project.json文件，它现在看起来（一部分）：

I use ASP.NET Core + Angular 2 template for Visual Studio. I have updated my project.json file and it looks now (part of it):

"dependencies": { "Microsoft.AspNetCore.AngularServices": "1.0.0-*", "Microsoft.AspNetCore.Authentication.Cookies": "1.1.0-preview1-final", "Microsoft.AspNetCore.Diagnostics": "1.1.0-preview1-final", "Microsoft.AspNetCore.Hosting.Abstractions": "1.1.0-preview1-final", "Microsoft.AspNetCore.Identity": "1.1.0-preview1-final", "Microsoft.AspNetCore.Identity.EntityFrameworkCore": "1.1.0-preview1-final", "Microsoft.AspNetCore.Mvc": "1.1.0-preview1-final", "Microsoft.AspNetCore.Razor.Tools": "1.0.0-preview3-final", "Microsoft.AspNetCore.Server.IISIntegration": "1.1.0-preview1-final", "Microsoft.AspNetCore.Server.Kestrel": "1.1.0-preview1-final", "Microsoft.AspNetCore.StaticFiles": "1.1.0-preview1-final", "Microsoft.EntityFrameworkCore": "1.1.0-preview1-final", "Microsoft.EntityFrameworkCore.Design": "1.1.0-preview1-final", "Microsoft.EntityFrameworkCore.Relational": "1.1.0-preview1-final", "Microsoft.EntityFrameworkCore.Relational.Design": "1.1.0-preview1-final", "Microsoft.EntityFrameworkCore.Sqlite": "1.1.0-preview1-final", "Microsoft.EntityFrameworkCore.SqlServer": "1.1.0-preview1-final", "Microsoft.EntityFrameworkCore.SqlServer.Design": "1.1.0-preview1-final", "Microsoft.EntityFrameworkCore.Tools": { "version": "1.0.0-preview3-final", "type": "build" }, "Microsoft.EntityFrameworkCore.Tools.Core": "1.0.0-rc2-final", "Microsoft.Extensions.Configuration.CommandLine": "1.1.0-preview1-final", "Microsoft.Extensions.Configuration.EnvironmentVariables": "1.1.0-preview1-final", "Microsoft.Extensions.Configuration.Json": "1.1.0-preview1-final", "Microsoft.Extensions.DependencyInjection.Abstractions": "1.1.0-preview1-final", "Microsoft.Extensions.FileProviders.Abstractions": "1.1.0-preview1-final", "Microsoft.Extensions.Logging": "1.1.0-preview1-final", "Microsoft.Extensions.Logging.Abstractions": "1.1.0-preview1-final", "Microsoft.Extensions.Logging.Console": "1.1.0-preview1-final", "Microsoft.Extensions.Logging.Debug": "1.1.0-preview1-final", "Microsoft.Extensions.Options": "1.1.0-preview1-final", "Microsoft.Extensions.Options.ConfigurationExtensions": "1.1.0-preview1-final", "Microsoft.Extensions.Primitives": "1.1.0-preview1-final" }, "tools": { "Microsoft.AspNetCore.Razor.Tools": "1.0.0-preview2-final", "Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview3-final" }, "frameworks": { "net461": {} },

，当我运行应用程序时出现错误：

and when I run an application I got an error:

System.IO.FileLoadException was unhandled Message: An unhandled exception of type 'System.IO.FileLoadException' occurred in Unknown Module. Additional information: Could not load file or assembly 'Microsoft.AspNetCore.Hosting.Abstractions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

您知道什么地方出了错吗？
