我正在使用cloud sql跟随书架教程： https://cloud.google.com/dotnet/getting-started/using-cloud-sql
在我的localmachine上运行应用程序时，应用程序运行正常。
将应用程序部署到Compute Engine时。服务器显示无法读取的运行时错误。
<customErrors mode="Off"/>
无助于显示错误。
通过RDP连接并在远程桌面上观看localhost上的应用程序时，会显示以下错误：

我无法声明应用程序为什么会出现此错误，因为我没有在项目中找到某种类型的引用到Razor的2.0.0.0版本。
System.Web.WebPages.Razor 3.0.0.0版包含在项目参考中。
降级到Razor版本2是否明智还是有其他解决方案？
答案 0 :(得分：1)
那么，有一个依赖于2.0版本，但你的系统上安装了3.0版本？在这种情况下，您可以尝试将绑定重定向从2.0声明为3.0。以下是有关如何声明绑定重定向的更多信息：

答案 1 :(得分：0)
解决问题的整体解决方案是：
在声明绑定重定向到以下错误后显示：
尝试使用安全透明方法'WebMatrix.WebData.PreApplicationStartCode.Start（）'来访问安全关键方法'System.Web.WebPages.Razor.WebPageRazorHost.AddGlobalImport（System.String）'失败。
这可以通过
解决之后显示以下错误
无法加载文件或程序集'WebMatrix.Data，Version = 3.0.0.0，Culture = neutral，PublicKeyToken = 31bf3856ad364e35'或其依赖项之一。定位的程序集的清单定义与程序集引用不匹配。 （HRESULT异常：0x80131040）
