软件包版本之间不匹配

Question

所以我想摆脱Visual Studio中的警告，我不知道是否有解决这个问题的简单方法。我可能将.Net Core 3.1与较旧的.NETFramework混合使用。我认为这可能是由于我导入了身份信息（Areas.Identity.Pages ...）。

解决此问题的正确方法是什么？

Answer 1

我找到了解决问题的方法。

删除软件包Microsoft.AspNet.WebHelpers并清除某些类中的“使用”语句引用确实删除了所有警告。幸运的是，这些都没有使用。

在使用.net core 3.1时，您应该在框架版本4.7.2中拥有所有项目
