.Net Core System.MissingMethodEx

使用 Add-Migration InitialCreate 生成数据库报错

• 错误明细

System.MissingMethodException : Method not found: 'System.Collections.Generic.IList`1<Microsoft.EntityFrameworkCore.Metadata.Conventions.IModelFinalizingConvention> Microsoft.EntityFrameworkCore.Metadata.Conventions.ConventionSet.get_ModelFinalizingConventions()'.
  Stack Trace:
     at Microsoft.EntityFrameworkCore.InMemory.Metadata.Conventions.InMemoryConventionSetBuilder.CreateConventionSet()

解决

• 把 microsoft.entityframeworkcore.tools 、microsoft.entityframeworkcore.design
  、microsoft.entityframeworkcore 升级到 6 就可以了（之前是7.0.x）
