azure - 缩小 Azure 上 FileLoadException 错误的范围

Question

我正在将 Suave 应用程序部署到 Azure Web 应用。应用程序失败并出现以下错误(可在 eventlog.xml 中找到)。

<Event>
    <System>
        <Provider Name=".NET Runtime"/>
        <EventID>1026</EventID>

如何确定丢失的确切文件或导致此问题的原因，以便修复它？

谢谢。

原来是FSharp.Core nuget包。从 FSharp.Core.3.1.2.5 升级到 FSharp.Core.4.0.0.1 解决了这个问题。我认为应用程序正在搜索 FSharp 4.4.0.0 并且此错误是因为它找到了旧版本。
