Question

nuget包Microsoft.Net.Http.2.0.20710.0由于使用了System.Net.Http，版本= 2.0.0.0而导致我发出构建警告，该版本与来自另一个软件包的版本4作斗争。

最好的方法是什么？ Microsoft.Net.Http.2.0.20710.0软件包是否已过时，我是否应该在项目中手动引用System.Net.Http，Version = 4.0.0.0？

构建输出是：

  There was a conflict between "System.Net.Http, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" and "System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a".
      "System.Net.Http, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" was chosen because it was primary and "System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" was not.

您可以尝试this Microsoft Connect bugreport中提到的解决方法。

或者你可以尝试在Web.config中添加这样的东西：

  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" />
        <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

修改

这是Connect Bug中的解决方法：

修改.......：＆lt;参考Include =“System.Net.Http”＆gt;
阅读......：＆lt; Reference Include =“System.Net.Http，Version = 4.0.0.0”＆gt;

System.Net.Http版本冲突导致构建警告
