无法加载文件或程序集'System.Net.Http [英] Could not load file or assembly 'System.Net.Http

问题描述

在我的生成输出的诊断视图中，显示了此冲突

In my diagnostic view of my build output shows this conflict

System.Net.Http，Version = 4.0.0.0，文化=中性，PublicKeyToken = b03f5f7f11d50a3a和 System.Net.Http，版本= 4.1.1.2，文化=中性，PublicKeyToken = b03f5f7f11d50a3a。 （TaskId：20）
之所以选择 System.Net.Http，版本= 4.0.0.0，文化=中性，PublicKeyToken = b03f5f7f11d50a3a是因为它是主要的，而 System.Net.Http，版本= 4.1.1.2，文化=中立，PublicKeyToken = b03f5f7f11d50a3a不是。 （TaskId：20）
引用取决于 System.Net.Http，版本= 4.0.0.0，文化=中性，PublicKeyToken = b03f5f7f11d50a3a [C：\Program Files（x86）\参考程序集\ Microsoft\Framework.NETFramework\v4.6.1\System.Net.Http.dll]。 （TaskId：20）

There was a conflict between "System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" and "System.Net.Http, Version=4.1.1.2, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a". (TaskId:20) "System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" was chosen because it was primary and "System.Net.Http, Version=4.1.1.2, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" was not. (TaskId:20) References which depend on "System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" [C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.6.1\System.Net.Http.dll]. (TaskId:20)

我通过添加RestSharp nuget包来到了这里。在安装此程序之前，我没有遇到任何问题，我认为它附带的其中一个部件可能导致了此问题。我尝试将其卸载，但是没有用。

I got here by adding the RestSharp nuget package. I was not having an issue until I installed this and I think one of the pieces that came with it may have caused this issue. I tried to uninstall it but that did not work.

推荐答案

安装Nuget包：System.Net.Http版本4.3.3安装正确的Version = 4.1.1.2

Installing Nuget Package: System.Net.Http version 4.3.3 installs the correct Version=4.1.1.2

这将在项目文件中产生以下引用：

this will result in the following reference in your project file:

<Reference Include="System.Net.Http, Version=4.1.1.2, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, processorArchitecture=MSIL">
      <HintPath>..\..\..\..\packages\System.Net.Http.4.3.3\lib\net46\System.Net.Http.dll</HintPath>
</Reference>
