我想部署一個aspnet核心應用到Azure。這似乎通過OK去了，但是當我嘗試啓動，我看到下面的錯誤應用...Aspnet核心Azure失敗，HTTP錯誤502.5 - 進程失敗
這個問題的常見原因：
應用程序未能啓動 申請程序開始，但隨後停止 應用程序啓動，但沒有聽配置的端口上
故障排除步驟：
檢查系統事件日誌中的錯誤消息 啓用日誌記錄的應用程序標準輸出消息 一個調試器附加到應用程序，並檢查
似乎有很多寫IIS在此，但不與Azure的，所以我在虧損在何處接下來看看。 Azure日誌未指示任何內容。
微軟的文檔給我這個信息...
Platform conflicts with RID
Browser: HTTP Error 502.5 - Process Failure
Application Log: - Application Error: Faulting module: KERNELBASE.dll Exception code: 0xe0434352 Faulting module path: C:\WINDOWS\system32\KERNELBASE.dll - IIS AspNetCore Module: Failed to start process with commandline '"dotnet" .\my_application.dll' (portable app) or '"PATH\my_application.exe"' (self-contained app), ErrorCode = '0x80004005'.
ASP.NET Core Module Log: Unhandled Exception: System.BadImageFormatException: Could not load file or assembly 'teststandalone.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format.
Troubleshooting:
If you published a self-contained application, confirm that you didn't set a platform in buildOptions of project.json that conflicts with the publishing RID. For example, do not specify a platform of x86 and publish with an RID of win81-x64 (dotnet publish -c Release -r win81-x64). The project will publish without warning or error but fail with the above logged exceptions on the server.
...但實際上並沒有告訴我幫助這些設置應該是什麼天青（或者如果它是相關的有），所以我」我不確定這是不是紅鯡魚。我沒有在我的dotnet發佈配置中指定-r開關。
我設法找到它一再拋出一些XML記錄事件日誌...
Failed to start process with commandline '"%LAUNCHER_PATH%" %LAUNCHER_ARGS%', ErrorCode = '0x80070002'.
經過調查，我發現我需要改變％LAUNCHER_PATH％和％LAUNCHER_ARGS％的值自己。我試過對web.config的各種更改，但沒有運氣。我的web.config現在看起來是這樣......
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<!--

<system.webServer>

<aspNetCore processPath="dotnet" arguments="site\wwwroot\Esoterix.Modle.Portalweb.dll" stdoutLogEnabled="true" stdoutLogFile="LogFiles\stdout" forwardWindowsAuthToken="false"/>
</system.webServer>
</configuration>
的路徑是從Azure的部署的根，這似乎對於stdout日誌文件路徑的工作（我正與報告的錯誤），但不應用程序本身。我仍然看到下面的錯誤..

這是重複4次
如果我看着我的標準輸出輸出我有以下...
Failed to load the dll from [\?\D:\home\site\wwwroot\hostpolicy.dll], HRESULT: 0x800700C1
An error occurred while loading required library hostpolicy.dll from [\?\D:\home\site\wwwroot]
如果我嘗試直接與這裏的web配置運行的exe ...
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<!--

</system.webServer>
</configuration>
然後我的標準輸出給了我下面的錯誤...
Failed to load the dll from [\?\D:\home\site\wwwroot\hostfxr.dll], HRESULT: 0x80070057
The library hostfxr.dll was found, but loading it from \?\D:\home\site\wwwroot\hostfxr.dll failed
Installing .NET Core prerequisites might help resolve this problem.
