在ServiceStack.Interfaces系统，版本= 4.0.0.0和系统，版本= 2.0.5.0之间的冲突

Question

我正在尝试解析生成警告，但是我无法通过这一个。我的目标是.Net 4.6.2，但似乎ServiceStack.Interfaces是针对较低版本？在详细的输出：

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". 

再后面许多常规组件看起来不错，那么冲突：

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 

所以看来ServiceStack.Interfaces原因造成的问题，但我需要引用它。我是否以某种方式引用了错误？我该如何解决警告？

Answer 1

ServiceStack.Interfaces是一个普通的PCL库，它是使用VS2017的新MSBuild格式引用的System.Runtime.Serialization构建的。它不explicitly reference any version，PCL版本决定它使用什么版本。

一旦.NET Standard 2.0和.NET Core 2.0发布，我们将把.NET标准库合并到一个ServiceStack的主版本5中的主ServiceStack NuGet包中，该版本将用.NET Standard替换PCL库，将解决此警告，但在进行任何结构更改之前，我们需要等待v5。
