Question

ASP.NET Core项目可以定位net461并在Azure网站上运行吗？

以下是经过尝试和失败的内容。

在定位netcoreapp1.0时有效，但当我将其更改为net461时（包括其他一些需要进行的编译更改），我收到以下错误：

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.AppContext, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

   at Microsoft.AspNetCore.Hosting.WebHostBuilder.Build()
   at WebApplication1.Program.Main(String[] args) in C:\Users\a\WebApplication1\Program.cs:line 14

具体地

System.IO.FileNotFoundException：无法加载文件或程序集＆＃39; System.AppContext ，版本= 4.0.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a＆＃39;或其中一个依赖项。系统找不到指定的文件。

在当地一切正常。

我天真地添加了nuget包以包含所需的程序集。

{
  "dependencies": {
    "Microsoft.AspNetCore.Diagnostics": "1.0.0",
    "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",
    "Microsoft.AspNetCore.Server.Kestrel": "1.0.1",
    "Microsoft.AspNetCore.StaticFiles": "1.0.0",
    "Microsoft.Extensions.Logging.Console": "1.0.0",
    "Newtonsoft.Json": "9.0.1",
    "System.AppContext": "4.1.0",
    "System.Reflection.TypeExtensions": "4.1.0",
    "System.Security.Cryptography.X509Certificates": "4.1.0"
  },

最终我遇到了不同的错误：

warn: Microsoft.AspNetCore.Server.Kestrel[0]
      Unable to bind to http://localhost:7762 on the IPv6 loopback interface.
System.AggregateException: One or more errors occurred. ---> Microsoft.AspNetCore.Server.Kestrel.Internal.Networking.UvException: Error -4089 EAFNOSUPPORT address family not supported

   at Microsoft.AspNetCore.Server.Kestrel.Internal.Http.Listener.<>c.<StartAsync>b__6_0(Object state)
   --- End of inner exception stack trace ---

我不知道从哪里开始。

虽然发布配置文件已选中选项＆＃34;删除目的地的其他文件＆＃34;仍然有一些文件遗留下来。

使用FTP并在发布之前手动删除所有文件解决了项目。

ASP.NET核心目标net461适用于Azure，假设您之前没有发布任何其他框架。

我在问题中添加的这些NuGet包也不需要，可以安全地从项目中删除。

"System.AppContext": "4.1.0",
"System.Reflection.TypeExtensions": "4.1.0",
"System.Security.Cryptography.X509Certificates": "4.1.0"

Azure Core中的ASP.NET Core定位net461
