DLL 重定向 - 内部版本号不匹配

Question

我似乎无法在 VS2010 ConsoleApplication 中加载 System.Net.Http.Formatting.dll，即使我已经设置了重定向。这是错误

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，据我了解，它正在寻找 System.Net.Http.Formatting，Version=4.0.0.0，但我的项目包含版本 4.0.21112.0，所以我设置了重定向（堆栈中也提到了跟踪，所以我知道重定向至少正在被拾取）

我的重定向是：

      <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>

它在 C:/VS2010/Accman.NET/AccManBackEndLibrary/bin 中找到较新的 DLL，但抱怨内部版本号不正确。但是，据我所知，整个版本号是正确的。

如果我运行 Powershell 命令来获取确切的版本号，它会返回相同的版本号：

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

请帮忙！我做错了什么？

谢谢

Answer 1

您可以从项目中删除 dll 引用并手动重新添加您拥有的 dll。
（解决方案资源管理器 -> 参考 -> 添加 -> 浏览）
应该解决问题。

Answer 2

回答 1

对，如果您想使用与 .NET 4 捆绑在一起的 System.Net.Http.Formatting、System.Net.Http 和 System.Net.WebRequest 版本，请先回答，这是我的（旧版）项目用途。

• 删除对这些包的每个引用（包括 packages.config 和 Nuget 包管理器）。此外，如果您的问题是因为您像我一样从 Nuget 安装了 NewtonSoft.Json，请也将其删除。

• 按照@user5226582 的建议手动添加它们（右键单击项目中的引用 -> 添加引用 -> Assemblies -> Extensions。注意我是从捆绑的 Extensions Assemblies 中选择它们的。

• 此外，如果您正在使用 NewtonSoft.Json.dll，请执行相同的操作。这也在程序集 -> 扩展中。

• 从 app.config 中删除与这些文件相关的任何 bindingRedirects

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

答案 2

System.Net.Http 已被 Microsoft.Net.Http 取代。删除任何现有的引用和相关的 bindingRedirects（如答案 1 所示）。

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

这似乎对我有用

Answer 3

包文件版本和程序集版本不一定对齐：
