.net core Microsoft.AspNetCore.Hosting.Abstractions清单定义与程序集引用不匹配

在类库中运行Entitfy framework core命令add migration MyMigrationName时，出现以下错误

无法加载文件或程序集 'Microsoft.AspNetCore.Hosting.Abstractions，版本=1.1.1.0， 区域性=中性，PublicKeyToken=adb9793829ddae60'或其 依赖关系。定位程序集的清单定义不正确 匹配程序集引用。来自HRESULT的异常：0x8013100

有趣的是，在我的应用程序中没有提到抽象

这是我的csproj

为我们工作，但在幕后如何工作？我们在使用AspNetCore.Identity和另一个EFCore迁移项目时遇到了类似的问题，出于某种原因，当从PCM运行更新数据库时，它会查找System.Data.Sql v4.1.X.X，而EFCore与System.Data.Sql v4.3.X.X捆绑在一起，为什么它首先会使用错误的绑定？
