c# - PostSharp AssemblyLoadException Autofac

Question

我正在设置一个新的解决方案，我想在其中使用最新的 Autofac (3.4) 和 PostSharp 3.1.42。引用 NuGet 包后出现以下错误，我无法弄清楚发生了什么。我从未选择 Autofac 3.3.0 包。

packages.config:

  <package id="Autofac" version="3.4.0" targetFramework="net451" />
  <package id="Autofac.Extras.Multitenant" version="3.1.1" targetFramework="net451" />
  <package id="Autofac.Mvc5" version="3.3.0" targetFramework="net451" />
  <package id="PostSharp" version="3.1.42" targetFramework="net451" />

MSBuild 日志:

Error   3   Unhandled exception (3.1.43.0, 32 bit, CLR 4.5, Release): PostSharp.Sdk.CodeModel.AssemblyLoadException: Cannot find assembly 'autofac, version=3.3.0.0, culture=neutral, publickeytoken=17863af14b0044da'. [Version mismatch]

有谁知道这是从哪里来的，我该如何解决这个问题？过去我用 Autofac 3.3.0 创建了一些项目。这可能是一些缓存吗？ PostSharp 和 Autofac 不在我的 GAC 中。

好的，所以我已经找到答案了。 PostSharp 以某种方式在错误的位置寻找错误的程序集。只需将其添加到您的 csproj 文件中即可修复它:

<PostSharpHostConfigurationFile>$(SolutionDir)path\to\your\web.config</PostSharpHostConfigurationFile>
