Microsoft.JSInterop.JSException: E0024 - DevExtreme包已经包括在内。请参阅: http://js.devexpress.com/error/21_2/E0024

Question

问题：I使用DevExpress v.21.1创建了一个XAF Blazor项目，其中asp.net核心(blazor)的仪表板特性不可用。稍后，在DevExpress v.21.2中添加了仪表板特性。在将我的项目更新到v21.2之后，我试图按照https://docs.devexpress.com/eXpressAppFramework/117449/analytics/dashboards-module?p=net5中提到的步骤在我的项目中添加仪表板特性，但是当我运行项目并尝试创建/查看仪表板时，它会显示以下异常。

Answer 1

经过几个小时的研究，我找到了解决办法。

在文件_Host.cshtml中，dx.all.js被包括在内，这造成了冲突。我删除了它，之后一切都进行得很好。
