解决方案中除1以外的所有项目都正在加载。该项目是DevExpress项目“ .dxjsproj”，如果没有DevExpress，将无法正确加载。尝试使用NuGet安装软件包时，会引发错误。
引发的错误是：
Error Could not install package 'DevExpress.Data 19.2.3'. You are trying to install this package into a project that targets 'MDD,Version=v8.1', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
应该发生 是项目正确加载，并且我可以进行处理，但是此错误阻止了此事情的发生。
