asp.net-mvc – 缺少Autofac 3.4,而3.5则被调用

试图运行成功构建的MVC 5.2项目会出现以下错误：

An exception of type ‘System.IO.FileLoadException’ occurred in
ProjectNamespace.WebUI.dll but was not handled in user code

Additional information: Could not load file or assembly ‘Autofac,

one of its dependencies. The located assembly’s manifest definition

我的web.config具有以下设置：

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

花了好几个小时试图解决它,但失败了.请帮忙.

最佳答案 这个问题已经变得非常普遍.当您使用Autofac,Autofac.Mvc5和Microsoft.AspNet.Mvc> 5.1.0软件包时,似乎会出现这种情况,即使Autofac.Mvc5可用于Microsoft.AspNet.Mvc(≥5.1.0&& < 6.0.0).

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

在你的配置中,如果你在第二个绑定中将它们移动到第一个绑定.在我加密某些配置设置的情况下,我修复了它,并且由于某种原因,绑定重定向没有被复制到生成的配置文件中.

我强烈推荐Assembly Binding Log Viewer,它帮助我解决了这个问题,尽管我的最终解决方案是懦弱的,转到Autofac3.4.0.0和Microsoft.AspNet.Mvc 5.1.0.我花了太多时间来解决问题.

此外,对于那些感兴趣的人,您可以使用nuget管理器来检测并填写程序集绑定重定向：Get-Project -All | Add-BindingRedirect(从here开始).之后可能需要一些补充,这取决于你的项目和参考文献,但至少它会给你一个干净的石板开始.

更新

Microsoft.AspNet.Mvc 5.2.3发布,所以我决定再试一次.我将“冲突”中涉及的每个包更新到最新版本(Autofac 3.5.2,Autofac.Mvc5 3.3.4,Microsoft.AspNet.Mvc 5.2.3).我更新了重定向绑定并且它有效.
