我將 View Variants 模塊安裝到我的 XAF winforms 21.2.7 專案中，它“在我的機器上作業”
當我部署和運行時，在 eXpressAppFramework.Log 中記錄以下呼叫堆疊時出現錯誤
Type: InvalidCastException
Message: Unable to cast object of type 'ModelDetailView' to type 'DevExpress.ExpressApp.ViewVariantsModule.IModelViewVariants'.
Data: 0 entries

我可以通過打開應用程式的預覽版本副本并登錄來解決此問題。
之后，我可以成功使用該應用程式。
或者，我可以從用戶漫游應用程式檔案夾中洗掉檔案 ModulesVersionInfo 以成功打開應用程式
從應用程式檔案夾中洗掉 modelassembly.dll 也可以解決此問題。
uj5u.com熱心網友回復：
從部署中洗掉 ModelAssembly.Dll 解決了這個問題。然后，當應用程式打開時，應用程式會正確創建 dll。
