无法加载文件或程序集-停止后再启动Azure应用服务

我正在将ASP.NET MVC Web应用程序发布到Azure应用程序服务。最初发布时运行find。如果我关闭了应用程序服务，然后在几个小时后再次启动它，当我尝试在浏览器中打开网站时收到此错误，直到应用程序关闭然后再次打开后，我才能弄清它为什么起作用： 

Server Error in '/' Application.

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].

我认为这与MyProject.Core.Plugins.PluginManager程序集有关。这是我的解决方案中的一个项目，该项目由Web应用程序使用。有时，当我在本地调试并更改到剃须刀页面时，会收到与此相关的错误。它不是很具体，也不会持续发生。我可以通过清理解决方案并重新构建来解决本地开发环境中的问题。我在本文中发布的错误与每次我关闭然后再打开应用程序服务时一致。

This帖子讨论了特定的错误，但这是一篇过时的文章，并谈到了我在Azure或开发环境中未使用的GAC。

答案 0 :(得分：1)

我必须将插件项目packages.json中的RazorEngine版本更改为Web项目所使用的相同版本。 

<package id="RazorEngine" version="3.4.1" targetFramework="net45" />

到

<package id="RazorEngine" version="3.7.2" targetFramework="net45" />

然后我跑了Update-Package -Reinstall RazorEngine

This帖子使我朝着正确的方向前进。 GeorgeChen的评论会有所帮助，但我在他发布之前找到了解决方案。
