将 rc2 asp.net 核心应用程序发布到 Azure

Question

我设法将我的应用程序从 VSO 发布到 Windows Azure。现在的问题是我的应用程序无法在 Azure 上启动并出现此错误（它在本地完美运行）：

System.TypeInitializationException: The type initializer for 'Microsoft.AspNetCore.Server.Kestrel.Networking.PlatformApis' threw an exception. ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime.InteropServices.RuntimeInformation, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

我尝试手动添加依赖，但没有解决问题:

"System.Runtime.InteropServices.RuntimeInformation": "4.0.0-rc2-23826"

这是我的配置

global.json:

{
  "projects": [ "src", "test", "lib" ],
  "sdk": {
    "version": "1.0.0-rc2-20221",
    "runtime": "clr",
    "architecture": "x86"
  }
}

project.json

  "compilationOptions": {
    "emitEntryPoint": true
  },
  "dependencies": {
    "Jil": "2.13.0",
    "JWT": "1.3.4",

在 IIS 上进行本地测试

Azure 在幕后使用 IIS。如果应用程序在 IIS 中运行，它通常会在 Azure Web 应用程序中运行。官方文档有clear instructions for publishing to IIS。一旦它在 IIS 中工作，将相同的东西部署到 Azure。

RC2 Azure 发布演练

以下是适合我的确切发布步骤。我制作了一个示例，其中使用了您问题中的 project.json 和 pushed the sample to GitHub.

克隆示例：

C:\> git clone https://github.com/bigfont/Whosebug.git
C:\> cd .\Whosebug\RuntimeInfo

然后发布项目：

C:\Whosebug\RuntimeInfo> dnvm use 1.0.0-rc2-20221 -runtime clr
C:\Whosebug\RuntimeInfo> dotnet restore
C:\Whosebug\RuntimeInfo> dotnet publish -c Release -o ./approot

这些命令以 RC2 运行时为目标，恢复 NuGet 包，并将发布配置发布到 approot 目录。这是结果：

C:\Whosebug\RuntimeInfo> dir
approot            
bin                
obj                            
Program.cs         
project.json       
project.lock.json     
wwwroot

现在，使用 FTP，将 approot 和 wwwroot 目录发布到 Azure 的 site 目录。

./site
    approot
    wwwroot

这是 Azure 中的结果。

最后的说明

小心"crossing the streams."您的应用在其项目中有两个发布版本。json/global.json 文件：1.0.0-rc2-20221 和 1.0.0-rc2-20270 .大概选一个比较好。
