I have a project created in VS 2003 that has a solution file that has VB.net, VC.net and VCSharp.net projects all-in-one.

I am trying to convert them to .net 2005 but it seems that the stand alone Express Editions of VB, VC, and VCSharp don't have that "bond" that the Visual Studio Suite would have so if I open the solution it asks which program to use to open it:
VB
VC
VCSharp.

No matter which one I pick, the parts of the group that belong to the other 2 platforms throw errors.

Is there a way for them to act like they are integrated so that all the pieces will properly load their respective parts?
