System， Version=4.0.0.0 和 System， Version = 2.0.5.0 in Servi

Question

我正在尝试解决构建警告，但我无法通过这个警告。我的目标是 .Net 4.6.2，但似乎ServiceStack.Interfaces的目标是较低的版本？在详细输出中：

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 AssembliesMicrosoftFramework.NETFrameworkv4.6.2System.dll].
1>          C:Program Files (x86)Reference AssembliesMicrosoftFramework.NETFrameworkv4.6.2System.dll
1>            Project file item includes which caused reference "C:Program Files (x86)Reference AssembliesMicrosoftFramework.NETFrameworkv4.6.2System.dll".

然后

是许多看起来不错的常规集会，然后是冲突：

1>      References which depend on "System, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e, Retargetable=Yes" [].

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

因此，似乎ServiceStack.Interfaces导致了问题，但我需要参考它。我以某种方式引用错误了吗？如何解决警告？

Answer 1

ServiceStack.Interfaces 是一个普通的 PCL 库，它只是使用 System.Runtime.Serialization 构建的，它使用 VS2017 的新 MSBuild 格式引用。它不显式引用任何版本，PCL 生成决定它使用的版本。

一旦.NET Standard 2.0和.NET

Core 2.0发布，我们将把.NET Standard库合并到ServiceStack的主要v5版本中的主ServiceStack NuGet包中，该版本将用.NET Standard替换PCL库，这将解决此警告，但我们需要等待v5才能进行任何结构更改。
