私はASP.NET Core + Angular 2 template for Visual Studioを使用します。私は私のproject.jsonファイルを更新している、それが（その一部）今になります

"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.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.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": {} 
    }, 

をし、私はエラーを得たアプリケーションを実行すると：

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) 

を、あなたは何であるか任意のアイデアを持っていますか違う？
