我已經創建了針對.net 4.6，ASP.NET Core和Windows 10的「Contracts」可移植類庫。該庫僅包含POCO類。便攜式庫的原因：發現不能解決的相同相關程序集的不同版本之間的衝突
我稱之爲「通訊」針對.NET 4.6和引用便攜庫的另一個項目：
當我嘗試生成項目，我得到警告：
Description: Found conflicts between different versions of the same dependent assembly that could not be resolved. These reference conflicts are listed in the build log when log verbosity is set to detailed.
Project: Communication
File: C:\Program Files (x86)\MSBuild\14.0\bin\Microsoft.Common.CurrentVersion.targets
Line 1819
詳細的構建日誌在這裏：buildlog.txt
爲什麼我得到t他的警告？如何擺脫它？
這裏有從生成日誌，可能是相關的部分：
