PostSharp AssemblyLoadException Autofac

Question

我正在设置一个新的解决方案，其中我想使用最新的Autofac (3.4)和PostSharp 3.1.42。在引用了NuGet包之后，我得到了下面的错误，我不知道发生了什么。我从未选择过Autofac 3.3.0软件包。

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]

有人知道这是从哪里来的吗?我怎样才能解决这个问题？在过去，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。

好吧，我已经找到答案了。不知怎么的，PostSharp正在寻找错误的装配在错误的位置。只需将此添加到csproj文件以修复它：

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