问题描述
我正在使用 PostSharp，而且效果很好.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 版本的旧项目.PostSharp 在构建时开始报告一个奇怪的错误:
I'm using PostSharp, and this was working fine. Recently, we upgraded some projects to the MVC version 5.2. Today, I loaded up an old project which was using version 4.0 of MVC. PostSharp started reporting a strange error on build:

我浏览了所有项目引用，但没有引用system.web.mvc, version=3.0.0.0 的项目.所有项目都参考 4.0.0.0.为什么提到版本 3.0.0.0?可能是从某些 GAC 或某些本地安装中找到它?
I went through all the project references, and there is no project which references system.web.mvc, version=3.0.0.0. All of the projects reference 4.0.0.0. Why is it mentioning version 3.0.0.0? Is it maybe finding it from some GAC or some local installation?
如果我从项目属性中禁用 PostSharp，项目将成功编译.所以它一定是与 PostSharp 相关的东西.任何帮助将不胜感激，因为我迷失了
If I disable PostSharp from the project properties, project compiles successfully. So it must be something related to PostSharp. Any help would be greatly appreciated as I'm lost about
推荐答案
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.您的 web.config 中有绑定重定向，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 *.config 文件的路径来实现.
This error is usually raised when some of the 3-rd party assemblies references older version of System.Web.Mvc. You have the binding redirect in your web.config, but you also need to tell PostSharp to use that configuration during build. You can do it by setting PostSharpHostConfigurationFile build property to the path of your *.config file.
<PropertyGroup>
<PostSharpHostConfigurationFile>web.config</PostSharpHostConfigurationFile>
</PropertyGroup>
