Well,last time when we migrated from VS 2005 to VS 2008 -there was no problem -as discussed here:

I have also VBP 6.7a -so your point is as soon as our C# projects are migrated to VS 2010 -current VBP project will not work anymore?
And the only solution is to migrate VBP to latest version (7.5 I guess)?
