asp.net - 面向完整 dotnet 框架的 ASP.NET Core Web 应用程序是否在 IIS 中工作？

Question

我正在尝试将在完整框架 (4.6.1) 之上开发的 ASP.NET Core 应用程序发布到 IIS。现在，代码只是使用 Visual Studio“ASP.NET Core (.NET Framework) 选项创建的基本模板代码。代码编译正常，但是当我将它发布到本地 IIS 时，它无法启动。我收到类似的错误

Unhandled Exception: System.TypeInitializationException: The type initializer for 'Microsoft.Extensions.PlatformAbstractions.PlatformServices' threw an exception. ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Reflection.TypeExtensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

我的 project.json 看起来像这样

    {
  "dependencies": {
    "Microsoft.AspNetCore.Mvc": "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.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"
  },

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

  "frameworks": {
    "net461": { }
  },

  "buildOptions": {
    "emitEntryPoint": true,
    "preserveCompilationContext": true
  },

  "publishOptions": {
    "include": [
      "wwwroot",
      "Views",
      "Areas/**/Views",
      "appsettings.json",
      "web.config"
    ]
  },

  "scripts": {
    "postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
  }
}

如果针对 dotnetcore 而不是 dotnet461，则相同的应用程序可以正常工作。所有 MS 文档似乎都说这种情况是可能的并且受到支持。 RTM 有什么变化吗？

如果您发布了针对 netcoreapp1.0 的相同应用程序先然后你 net4x版本然后我认为这是Web Deploy中的一个错误。我在发布到 Azure 时遇到了类似的问题 - https://github.com/aspnet/Hosting/issues/801#issuecomment-227920473 .我通过首先手动删除目标文件夹中的所有内容然后发布针对 net4x 的应用程序来修复它。再次( https://github.com/aspnet/Hosting/issues/801#issuecomment-228123238 )。我认为如果名称相同，Web Deploy 会留下一些 dll 或不更新，然后它们被拾取但失败，因为它们与目标框架不匹配并且它们的依赖项丢失。我还发现选中 Web Deploy 中的复选框以删除目的地的文件并没有解决问题，并就此打开了一个问题。
