ASP.NET 以完整的 dotnet 框架为目标的核心 Web 应用程序是否可以在 IIS 中运行？

Question

我正在尝试将在完整框架 (4.6.1) 之上开发的 ASP.NET 核心应用程序发布到 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.

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%" ]
  }
}

相同的应用程序如果针对 dotnetcore 而不是 dotnet461 工作正常。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？

如果您首先发布了针对 netcoreapp1.0 的同一应用程序，然后发布了 net4x 版本，那么我认为这是 Web 部署中的错误。我在发布到 Azure 时遇到了类似的问题 - https://github.com/aspnet/Hosting/issues/801#issuecomment-227920473. I fixed it by first manually deleting all the contents in the target folder and then publishing the application targeting net4x again (https://github.com/aspnet/Hosting/issues/801#issuecomment-228123238)。我认为 Web Deploy 会留下一些 dll，或者如果名称相同则不会更新，然后将它们拾取但失败，因为它们与目标框架不匹配并且缺少它们的依赖项。我还发现选中 Web Deploy 中的复选框以删除目标位置的文件并没有解决问题，并为此打开了一个问题。

Does ASP.NET Core web application targeting full dotnet framework work in IIS?

.net-core
