c# - PostSharp 问题无法找到 system.web.mvc 的程序集，版本 = 3.0.0.0 当没有项目引用它时

Question

我正在使用 PostSharp，它运行良好。最近，我们将一些项目升级到了 MVC 5.2 版本。今天，我加载了一个使用 MVC 4.0 版的旧项目。 PostSharp 开始报告一个奇怪的构建错误:

Error   17  Unhandled exception (3.1.42.0, 32 bit, CLR 4.5, Release): PostSharp.Sdk.CodeModel.AssemblyLoadException: Cannot find assembly 'system.web.mvc, version=3.0.0.0, culture=neutral, publickeytoken=31bf3856ad364e35'. [Version mismatch]

我查看了所有项目引用，没有引用system.web.mvc, version=3.0.0.0 的项目。所有项目都引用 4.0.0.0。为什么提到版本 3.0.0.0？是否可以从某些 GAC 或某些本地安装中找到它？

如果我从项目属性中禁用 PostSharp，项目将成功编译。所以它一定是和 PostSharp 有关的东西。任何帮助将不胜感激，因为我迷失了

当某些第 3 方程序集引用旧版本的 System.Web.Mvc 时，通常会引发此错误。您在 web.config 中有绑定(bind)重定向，但您还需要告诉 PostSharp 在构建期间使用该配置。您可以通过将 PostSharpHostConfigurationFile 构建属性设置为您的 *.config 文件的路径来实现。

<PropertyGroup> 
  <PostSharpHostConfigurationFile>web.config</PostSharpHostConfigurationFile> 
</PropertyGroup>
