DLL重定向 - 内部版本号不匹配

Question

我似乎无法加载VS2010 ConsoleApplication中的System.Net.Http.Formatting.dll，即使我设置了重定向。这里的错误

System.IO.FileNotFoundException: Could not load file or assembly 'System.Net.Http.Formatting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

所以，我的理解是，它在寻找System.Net.Http.Formatting，版本= 4.0.0.0，但我的项目中包含的版本4.0.21112.0，所以我成立了一个重定向（这也是在堆栈跟踪中提到，所以我知道重定向至少被拾起）

我重定向是：

 <dependentAssembly> 
    <assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" culture="neutral" /> 
    <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.21112.0" /> 
    </dependentAssembly> 

它发现在C较新的DLL：/VS2010/Accman.NET/ AccManBackEndLibrary/bin，但抱怨内部版本号不正确。不过，据我所知，整个版本号是正确的。

如果我运行PowerShell命令得到它返回相同数量的确切版本号：

PS F:\> (get-item C:\VS2010\Accman.NET\AccManBackEndLibrary\bin\System.Net.Http.Formatting.dll).VersionInfo 

ProductVersion FileVersion  FileName 
-------------- -----------  -------- 
4.0.21112.0  4.0.21112.0  C:\VS2010\Accman.NET\AccManBackEndLibrary\bin\System.Net.Http.Formatting.dll 

请帮帮忙！我究竟做错了什么？

感谢

Answer 1

你可以从项目中删除DLL的参考和手动重新添加你的DLL。
（解决方案资源管理器 - >参考 - >添加 - >浏览）
应该解决问题。

回答1

吧，如果你想使用随.NET 4捆绑System.Net.Http.Formatting，System.Net.Http和System.Net.WebRequest版本的第一个答案，这是我的（遗留）项目使用的。

• 删除对这些包的每一个引用（包括packages.config和Nuget包管理器）。另外如果你的问题出现了，因为你像我一样从Nuget安装了NewtonSoft.Json，那么也删除它。

• 手动将其添加为@ user5226582建议（右键单击引用在项目 - >添加引用 - >组件 - >扩展注意我选择了他们从捆绑的扩展组件

• 而且，。如果你正在使用它的NewtonSoft.Json.dll做同样这也是在组件 - >扩展

• 从app.config中

0123删除与这些文件的任何bindingRedirects

现在这是一个公平的竞争环境，因为所有的DLL都来自同一个地方，并且应该相互兼容。

答案2

System.Net.Http已取代Microsoft.Net.Http。删除任何现有的引用和相关的绑定重定向（如答案1）。

• 使用的NuGet安装Microsoft.Net.Http
• 使用的NuGet安装NewtonSoft.Json（如果使用）

这似乎为我工作
