当 运行 我的本地计算机上的应用程序运行正常时。
当应用程序部署到 Compute Engine 时。服务器显示无法读取的运行时错误。

无助于显示错误。
当通过 RDP 连接并在远程桌面上查看本地主机上的应用程序时，显示以下错误：

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].

我无法声明应用程序出现此错误的原因，因为我没有在项目中找到对 2.0.0.0 版 Razor 的某种引用。
System.Web.WebPages.Razor 的 3.0.0.0 版作为项目参考包含在内。
降级到 Razor 版本 2 是否明智，还是有其他解决方案？
所以，对 2.0 版本存在依赖性，但您的系统上安装了 3.0 版本？在这种情况下，您可以尝试声明从 2.0 到 3.0 的绑定重定向。以下是有关如何声明绑定重定向的更多信息：
https://msdn.microsoft.com/en-us/library/7wd6ex19(v=vs.110).aspx
解决问题的总方案是：
- 声明绑定重定向
正如@Mete Atamel 对此post 的回答
声明绑定后重定向到以下错误显示：
Attempt by security transparent method 'WebMatrix.WebData.PreApplicationStartCode.Start()' to access security critical method 'System.Web.WebPages.Razor.WebPageRazorHost.AddGlobalImport(System.String)' failed.
这可以通过
来解决
- 使用 NuGet 控制台安装包 Microsoft.AspNet.WebHelpers，如
中所述
之后出现如下错误
Could not load file or assembly 'WebMatrix.Data, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
