两个引用的程序集之间的冲突

我正在使用.Net Core工作正常的应用程序.但是,今天我发现output包含警告.将日志级别设置为detailedI后发现如下:

These reference conflicts are listed in the build log when log verbosity is set to detailed.

这条线There was a conflict between "Microsoft.Extensions.DependencyModel....我不知道如何处理这个警告,因为我只是使用.Net standard 1.1和System.Reflection.Emit打包,NuGet不参考任何其他内容.

当然,我可以忽略这个警告,但寻找一些解决方案
