Encountered multiple versions of the assembly with GUID Try pre-importing one of these assemblies 错误解决方法

vs2008 开发的 winform程序迁移到 vs2010后编译发生错误。

“Encountered multiple versions of the assembly with GUID ****************** Try pre-importing one of these assemblies”

vs2008中最高用framework3.5，升级后引用的dll、com组件可能已经是针对4.0的了。
