我有一個正在撰寫的 WPF 應用程式，但是在測驗記錄的插入時，我遇到了以下例外。
應用程式使用 .NET 4.8，我使用物體框架 5。
我得到的例外是：
System.TypeInitializationException: 'The type initializer for 'ExtentPlaceholderCreator' threw an exception.'
EntryPointNotFoundException: Unable to find an entry point named 'SetClrFeatureSwitchMap' in DLL 'SqlServerSpatial110.dll'.
堆疊跟蹤是：

在線查看我可以看到我需要在我的 .config 檔案中參考的建議，但是我只能看到 Web 表單或 mvc 而不是 WPF 的回應，所以不確定它是與我的 app.config 相同的問題還是不同的問題”看起來像那些例子？
uj5u.com熱心網友回復：
在找到我更新的物體框架更新后，然后建議有一個超出范圍的十進制記錄，所以我已經解決了它！
