【问题描述】：
我有两个项目：
1) 一个以 .net Framework 2.0 为目标的用 Visual C++ 2005 编写的项目。
2) Visual C# 2010 中的一个项目，它以 .net framework 2.0 为目标并包含 C++ DLL。
当我构建引用 C++ 程序集的 C# 项目时，我收到如下错误：
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(1360,9): warning MSB3258: The primary reference "ScannerWizard" could not be resolved because it has an indirect dependency on the .NET Framework assembly "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" which has a higher version "4.0.0.0" than the version "2.0.0.0" in the current target framework.

如果我制作项目 4.0，它不会给出这些错误。显然，我不应该让它以 4.0 为目标来使用 2.0 程序集。
知道如何解决这个问题吗？
【问题讨论】：
-
您是否转换了 C++/CLI 项目？不要，只添加引用。
-
不，ScanWizard DLL 最后一次编译是在 4 年前，在 Visual C++ 2005 中。它没有被重新编译或任何东西。两者都不需要，但是如果我在编译时可以做一些不同的事情，我很乐意这样做。
-
通过使用 ILSpy，我发现 VC++ DLL 引用了 MFCMIFC80，它依赖于 mscorlib 和 System.它不是使用 2.0 版本，而是使用系统上的最新版本，即 4.0。一定有办法阻止它这样做？
-
警告导致通过该 DLL 公开的对象不可用。
-
删除 DLL 似乎是一种解决问题的高风险方法（尽管它是成功的）。也许FuslogVW 可以让您找出正在加载的程序集链，而这反过来又可以让您write a policy 重定向到 2.0 程序集。
