未能從程序集加載類型 - ASP.NET核心

爲MVC將中間件ASP.NET核心解決方案未能從程序集加載類型 - ASP.NET核心

System.TypeLoadException 未能加載類型「Microsoft.Extensions.DependencyInjection當我收到以下錯誤。從組件 'Microsoft.Extensions.DependencyInjection.Abstractions，版本= 1.0.0.0，文化=中性公鑰= adb9793829ddae60' Extensions.ServiceCollectionExtensions。

我在project.json文件相關的

{ 
    "dependencies": { 
    "Microsoft.NETCore.App": { 
     "version": "1.0.0", 
     "type": "platform" 
    }, 
    "Microsoft.AspNet.Mvc": "6.0.0-rc1-final", 
    "Microsoft.AspNetCore.Diagnostics": "1.0.0", 
    "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0", 
    "Microsoft.AspNetCore.Server.Kestrel": "1.0.0", 
    "Microsoft.Extensions.Logging.Console": "1.0.0", 
    "Microsoft.Extensions.Configuration.Json": "1.0.0", 
    "Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore": "1.0.0", 
    "Microsoft.AspNet.Diagnostics": "1.0.0-rc1-final", 
    "Microsoft.AspNet.StaticFiles": "1.0.0-rc1-final", 
    "Microsoft.AspNetCore.StaticFiles": "1.0.0", 
    "Microsoft.AspNetCore.Mvc.Core": "1.0.0", 
    "Autofac.Extensions.DependencyInjection": "4.0.0-rc3-309" 
    },

有不同的版本在JSON文件之間的衝突？

這裏是我的解決方案 -

你嘗試用1.0.0更換所有的RC {1,2,3} .NET核心的依賴？ – MMK

我替換了兩個，但沒有更改「Microsoft.AspNet.Diagnostics」：「1.0.0」，「Microsoft.AspNetCore.StaticFiles」：「1.0.0」， – Aindriu

你能在你的project.json缺少這兩個中的一個？

"Microsoft.Extensions.DependencyInjection":"1.0.0", 
"Microsoft.Extensions.DependencyInjection.Abstractions":"1.0.0",

不，仍然收到相同的錯誤 – Aindriu

你有沒有運行dotnet恢復在添加它們並仍然出現相同的錯誤之後？ –

是的，我運行dotnet恢復，但仍然是相同的錯誤。我似乎有這個解決方案的中間件問題，但安裝了正確的NuGet軟件包，看不到問題是什麼？ – Aindriu

我創建使用「喲ASPNET」，並具有以下project.json一個全新的Web API應用程序：

"Microsoft.AspNetCore.Mvc": "1.0.0", 
"Microsoft.AspNetCore.Mvc.Core": "1.0.0", 
"Microsoft.AspNetCore.StaticFiles": "1.0.0", 
"Microsoft.AspNetCore.Server.IISIntegration": "1.0.0", 
"Microsoft.AspNetCore.Server.Kestrel": "1.0.0", 
"Microsoft.Extensions.Configuration.EnvironmentVariables": "1.0.0", 
"Microsoft.Extensions.Configuration.FileExtensions": "1.0.0", 
"Microsoft.Extensions.Configuration.Json": "1.0.0", 
"Microsoft.Extensions.Configuration.CommandLine": "1.0.0", 
"Microsoft.Extensions.Logging": "1.0.0", 
"Microsoft.Extensions.Logging.Console": "1.0.0", 
"Microsoft.Extensions.Logging.Debug": "1.0.0", 
"Microsoft.Extensions.Options.ConfigurationExtensions": "1.0.0"

爲了得到你是什麼後，我不得不添加兩個微軟AspNetCore.Mvc.Core和Microsoft.AspNetCore.StaticFiles。

讓我知道是否能解決它。

我認爲AspNetCore和ASPNet之間存在混淆。 IT有點混亂，但沒有工作，但我使用上述依賴 – Aindriu

因此，如果你刪除所有的依賴關係，並添加上述那些仍然失敗？ –

我不得不創建一個新項目並使其工作。我無法弄清楚問題是什麼，但我認爲這是ASP.NET和ASP.NET CORE 1.0之間的衝突 - 我認爲他們都做了類似的事情，但我做了一些交叉。 – Aindriu
