加载视图

Question

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，调用我的Index操作时出现System.TypeLoadException错误：

  

类型＆＃39; System.TypeLoadException＆＃39;的例外情况发生在Microsoft.AspNet.Mvc.ViewFeatures.dll但未在用户代码中处理

     

其他信息：无法加载类型   ＆＃39; Microsoft.Extensions.DependencyInjection.ServiceProviderExtensions＆＃39;   来自assembly＆＃39; Microsoft.Extensions.DependencyInjection.Abstractions，   Version = 1.0.0.0，Culture = neutral，PublicKeyToken = adb9793829ddae60

这就是错误似乎发生的地方：

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

到目前为止，我的project.json文件看起来像这样：

{
  "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"
      ]
    }
  },

任何人都知道问题是什么？

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

{
  "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"
      ]
    }
  },
