无法加载文件或程序集 - 停止后启动 Azure 应用服务

Question

我正在将 ASP.NET MVC Web 应用程序发布到 Azure 应用服务。它在最初发布时运行 find 。如果我关闭应用程序服务，然后在几个小时后再次启动它，当我尝试在浏览器中打开该站点时出现此错误，我无法弄清楚它为什么工作，直到应用程序关闭然后再次打开：

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].

我发现这与导致它的 MyProject.Core.Plugins.PluginManager 程序集有关。这是我的解决方案中的一个项目，由 Web 应用程序使用。有时，当我在本地调试并更改剃须刀页面时，我会收到与此相关的错误。这不是很具体，也不会始终如一地发生。我可以通过清理解决方案来修复我的本地开发环境，然后重建。我在这篇文章中发布的错误与我每次关闭应用服务时一致。

This 帖子讨论了具体错误，但这是一篇旧帖子，讨论了我没有在 Azure 或我的开发环境中使用的 GAC。

Answer 1

我不得不将插件项目 packages.json 中的 RazorEngine 版本更改为 Web 项目使用的相同版本。

<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 帖子让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。
