我们的项目后端是. Net标准，前端是. Net Framework 4.7.2，我们将我们的C#项目迁移到**. Net 6**。
我们在UI组件上使用了DevExpress工具包。迁移后，虽然WinForm设计器工作正常，但我在报告设计器中遇到了错误。
错误提示System. Runtime. Serialization. Primitives Version www.example.comnot found.当我查看nuget包时，我发现它在4.3.0版本之前就存在了。SDK不应该提供这个包吗？我很困惑。6.0.0.0**not found. When I looked at the nuget packages, I saw that it existed until version 4.3.0. Shouldn't the SDK provide this package? I'm so confused.

Nuget软件包管理器：

我重新安装了Dotnet运行时，重新安装了DevExpress工具，手动重新安装了RepxPackage，安装了Runtime.Primitives4.3.0。没有一个是解决方案。

• • 编辑：我添加了新的报告到相同的项目和相同的文件夹，并工作，报告设计器打开。我应该如何修复旧的报告到新的。**

我复制了报告的C#文件和设计师到新的工作报告。那出现。

感谢您提前回答。
