在ServiceStack.Interfaces系統，版本= 4.0.0.0和系統，版本= 2.0.5.0之間的衝突

Question

我正在嘗試解析生成警告，但是我無法通過這一個。我的目標是.Net 4.6.2，但似乎ServiceStack.Interfaces是針對較低版本？在詳細的輸出：

There was a conflict between "System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" and "System, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes". 
1>  "System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" was chosen because it was primary and "System, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes" was not. 
1>  References which depend on "System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" [C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.2\System.dll]. 
1>   C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.2\System.dll 
1>   Project file item includes which caused reference "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6.2\System.dll". 

再後面許多常規組件看起來不錯，那麼衝突：

1>  References which depend on "System, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes" []. 
1>   C:\Code\Trunk\packages\ServiceStack.Interfaces.4.5.6\lib\portable-wp80+sl5+net45+win8+wpa81+monotouch+monoandroid+xamarin.ios10\ServiceStack.Interfaces.dll 
1>   Project file item includes which caused reference "C:\Code\Trunk\packages\ServiceStack.Interfaces.4.5.6\lib\portable-wp80+sl5+net45+win8+wpa81+monotouch+monoandroid+xamarin.ios10\ServiceStack.Interfaces.dll". 
1>    ServiceStack.Common, Version=4.5.6.0, Culture=neutral, processorArchitecture=MSIL 
1>    ServiceStack.Interfaces, Version=4.0.0.0, Culture=neutral, PublicKeyToken=e06fbc6124f57c43, processorArchitecture=MSIL 
1>    ServiceStack.Redis, Version=4.5.6.0, Culture=neutral, processorArchitecture=MSIL 

所以看來ServiceStack.Interfaces原因造成的問題，但我需要引用它。我是否以某種方式引用了錯誤？我該如何解決警告？

Answer 1

ServiceStack.Interfaces是一個普通的PCL庫，它是使用VS2017的新MSBuild格式引用的System.Runtime.Serialization構建的。它不explicitly reference any version，PCL版本決定它使用什麼版本。

一旦.NET Standard 2.0和.NET Core 2.0發佈，我們將把.NET標準庫合併到一個ServiceStack的主版本5中的主ServiceStack NuGet包中，該版本將用.NET Standard替換PCL庫，將解決此警告，但在進行任何結構更改之前，我們需要等待v5。
