我有两个项目：
1）用Visual C ++ 2005编写的以.net Framework 2.0为目标的项目。
2）Visual C＃2010中的一个项目，它针对.net framework 2.0并包含C ++ DLL。
当我构建引用C ++程序集的C＃项目时，我得到的错误如下：
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.

如果我使项目4.0，它不会给出这些错误。显然，我不应该让目标4.0使用2.0程序集。
我对如何解决此问题有任何想法？

C ++项目使用的是v100平台工具集。这使它依赖于某些库的4.0 .NET版本。将工具集更改为v90可解决此问题。如果您没有v90工具集，则可能需要安装它...
