我搜查SO和谷歌，以及似乎不同版本的.NET是罪魁祸首。我的问题是：我该如何解决这个问题

I searched SO and Google, and it seems that the different version of .NET is the culprit. My question is: How do I fix this?

推荐答案

编译VS2005项目使用相同的.NET版本为您的VS2003项目使用。 或者，这取决于你的VS2003项目，反射体的大小和重写。这对在这里的项目普遍的做法，在一些模糊的原因是没有更多的VSS版本。

Compile the VS2005 Project with the same .Net Version as your VS2003 Project uses. Or, depending of the size of your VS2003 Project, reflector and rewrite it. That's common practice for projects over here, where for some obscure reason there is no more VSS version available.
