加载视图时抛出 ASP.NET Core System.TypeLoadException答案

【问题标题】：ASP.NET Core System.TypeLoadException Thrown When Loading View加载视图时抛出 ASP.NET Core System.TypeLoadException

【问题描述】：

我正在尝试使用 ASP.NET Core。当我尝试运行 ASP.NET Core Web 应用程序时，在调用我的 Index 操作时收到 System.TypeLoadException 错误：

Microsoft.AspNet.Mvc.ViewFeatures.dll 中出现“System.TypeLoadException”类型的异常，但未在用户代码中处理

附加信息：无法加载类型 'Microsoft.Extensions.DependencyInjection.ServiceProviderExtensions' 从程序集'Microsoft.Extensions.DependencyInjection.Abstractions，版本=1.0.0.0，文化=中性，PublicKeyToken=adb9793829ddae60

这似乎是错误发生的地方：

public class HomeController : Controller
    {
        public IActionResult Index()
        {
            return View();
        }
    }

到目前为止，我的 project.json 文件如下所示：

{
  "dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.0.0",
      "type": "platform"
    },
    "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.AspNet.Mvc.ViewFeatures": "6.0.0-rc1-final",
    "Microsoft.AspNet.Mvc.Core": "6.0.0-rc1-final",
    "Microsoft.AspNetCore.Mvc.Core": "1.0.0",
    "Microsoft.AspNetCore.StaticFiles": "1.0.0",
    "Microsoft.AspNetCore.Razor.Tools": {
      "version": "1.0.0-preview2-final",
      "type": "build"
    },
    "Microsoft.AspNetCore.Mvc": "1.0.0",
    "Microsoft.AspNetCore.Mvc.TagHelpers": "1.0.0"
  },

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

  "frameworks": {
    "netcoreapp1.0": {
      "imports": [
        "dotnet5.6",
        "portable-net45+win8"
      ]
    }
  },

有人知道问题出在哪里吗？

我认为您无法正确迁移 rc1 到 1.0 版本。你的project.json 应该是这样的（删除rc1 包）：

{
  "dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.0.0",
      "type": "platform"
    },
    "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.AspNetCore.StaticFiles": "1.0.0",
    "Microsoft.AspNetCore.Razor.Tools": {
      "version": "1.0.0-preview2-final",
      "type": "build"
    },
    "Microsoft.AspNetCore.Mvc": "1.0.0",
    "Microsoft.AspNetCore.Mvc.TagHelpers": "1.0.0"
  },

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

  "frameworks": {
    "netcoreapp1.0": {
      "imports": [
        "dotnet5.6",
        "portable-net45+win8"
      ]
    }
  },
