Question

我有一个依赖于旧版System.Net.Http.Primitives的DLL。

由于此调用此dll会导致T4模板中出现以下错误

我该如何解决这个问题？

我尝试添加到此dll的app.config，但没有效果。

    <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Net.Http.Primitives" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-4.2.29.0" newVersion="4.2.29.0" />
      </dependentAssembly>
    </assemblyBinding>
    </runtime>

Answer 1

答案如下：

日志：使用应用程序配置文件： %LOCALAPPDATA%\Microsoft\VisualStudio\14.0

E.g。 C:\Users\username\AppData\Local\Microsoft\VisualStudio\14.0

如果需要在T4中重定向程序集绑定，则必须在Visual Studio的配置文件中添加它们。
也许它不直观，但这就是它的工作方式..

P.S。请记住重新启动Visual Studio 以加载更改。

Answer 2

我解决了类似的问题，因为必须在主WPF应用程序中安装Microsoft HTTP Client Library 4.2.29.0，即使我在那里没有使用它们。我的TESTER应用程序对我的YouTubeDataV3.DLL程序集有效，但当我尝试从WPF应用程序中使用它时（所有项目都设置为NET 4.5）。

我最初尝试手动修改app.config和C：\ Windows \ Microsoft.NET \ Framework \ v4.0.30319 \ config \ machine.config，但我总是看到相同的异常

System.IO.FileNotFoundException: Could not load file or assembly 'System.Net.Http.Primitives, Version=4.2.29.0...

System.IO.FileNotFoundException: Could not load file or assembly 'System.Net.Http.Primitives, Version=1.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

我认为NuGet存在一些问题，因为它将包文件夹对等存储到解决方案中，而不是与NuGet管理的项目引用相对应。 IOW，如果您有x个客户端项目应用程序正在使用程序集“A”，其引用由NuGet管理，那么最终会在解决方案（.SLN）文件所在的地方分散x个包文件夹。这真的很难看，记住，所有的垃圾:)，将被复制到bin / debug和bin / release :(再一次。这是多么浪费的方法。

Answer 3

如果你想调试T4：

您需要创建一个配置文件＆＃34; T4VSHostProcess.exe.config＆＃34;在Visual Studio路径中（例如C：\ Program Files（x86）\ Microsoft Visual Studio 14.0 \ Common7 \ IDE），并使用适当的程序集绑定重定向。

设置devenv.exe.config仅在不调试时才有效。

如何在T4中进行程序集重新绑定
