Question

我有一个“ Dell Hell”问题。在解决方案中的各个项目中，我安装了System.Net.Http 4.3.3软件包，该软件包还安装了System.IO 4.3.0和System.Runtime 4.3.0软件包作为依赖项，但应用程序未加载此程序集的正确版本。在Web.config文件中，我具有以下绑定重定向：

<dependentAssembly>
    <assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-4.1.1.2" newVersion="4.1.1.2" />
  </dependentAssembly>    
<dependentAssembly>
        <assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-4.1.2.0" newVersion="4.1.2.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.IO" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-4.1.2.0" newVersion="4.1.2.0" />
      </dependentAssembly>

但是在运行时，应用程序会加载所有程序集的4.0.0.0版。我试图在程序集加载日志中找到问题，但在其中未找到任何有用的信息。例如，System.Net.Http程序集日志为：

*** Assembly Binder Log Entry  (10/01/2019 @ 3:03:33 p.m.) ***
The operation was successful.
Bind result: hr = 0x0. La operación se completó correctamente.

我试图更新所有nuget软件包，以找到一些需要4.0.0.0版本的旧依赖性，但是应用程序始终加载错误版本。

无法卸载和重新安装nuget软件包，主项目中最多有90个软件包引用。

我以为问题是由项目中的.Net3.5参考引起的，但是删除此问题我仍然遇到相同的问题。

谢谢
