Question

将我的项目从Autofac 2.6.3.862升级到3.4.0.0后，出现以下错误。我甚至没有在解决方案的任何项目中添加对Autofac 3.3.0.0的任何引用。

更新：我还将程序集重定向绑定添加到web.config，但仍然有错误。

<runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
                <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="5.2.2.0" />
            </dependentAssembly>
    <dependentAssembly>
                <assemblyIdentity name="Autofac" publicKeyToken="17863af14b0044da" />
                <bindingRedirect oldVersion="1.0.0.0-3.4.0.0" newVersion="3.4.0.0" />
            </dependentAssembly>
        </assemblyBinding>
    </runtime>

我还尝试将Autofac 3.3.0.0添加到GAC，但效果不佳。

Answer 1

您可能需要在web.config中进行绑定重定向。对于版本3.5，我的看起来像：

  <dependentAssembly>
    <assemblyIdentity name="Autofac" publicKeyToken="17863af14b0044da" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-3.5.0.0" newVersion="3.5.0.0" />
  </dependentAssembly>

Answer 2

它需要将<role name>.dll.config文件添加到您的解决方案（与web.config或app.config相同的级别），并将“复制到输出目录”属性设置为“始终复制”。此文件应包含bindingRedirect设置。我有同样的错误：FileLoadException: Could not load file or assembly in WebRole (recycling instance)

我遇到了一个单元测试库的问题，我从旧的XAML构建迁移到新的vNext构建。我为所有使用AutoFac的库配置了程序集版本绑定重定向。我仍然在输出中遇到问题。

我最终发现绑定重定向信息仅输出（在bin文件夹中）与项目对应的DLL，而不是所有其他包含的DLL。在我的例子中，我引用了另一个（单元测试）库，它也需要AutoFac。该库中包含单元测试，这些测试也由构建过程检测到，并且在运行时失败。问题是未引用引用库中定义的绑定重定向，因为bin文件夹中没有引用库的.config文件。

所以我通过不让单元测试库引用其他单元测试库来解决这个问题。作为一种解决方法，使用公共代码项目或公共C＃项目库来获取公共代码。

此处还有关于为什么AutoFac需要程序集绑定的其他信息：Why don’t all Autofac packages target the latest Autofac core?

无法加载文件或程序集Autofac，Version = 3.3.0.0
