推荐答案

.Net 4与.net的早期版本向后兼容.

这意味着您想重新编译使用.Net早期版本设计的应用程序，并以新的.Net4框架为目标.

有关详细信息，请参见此处:

另一方面，.Net2、3、3.5和4可以愉快地共存于同一台PC上，并且每个应用程序都将使用它所针对的.Net版本.

所以基本上您的问题根本不是问题.

Hi,

.Net 4 is backward compatible with the previous versions of .net.

It means that is you want to recompile an application that was designed using a previous version of .Net and target the new .Net4 framework it will work.

See here for details:
http://msdn.microsoft.com/en-us/library/ff602939.aspx[^]

In another hand .Net2, 3, 3.5 and 4 can happily coexist on the same PC and each application will use the version of .Net it is targeting.

So basically your issue is not an issue at all.

它的设计使其没有问题.

It was designed such that this is not an issue.

I think the following links will help you too:
