Well, uninstall your framework  then, saving your framework samples incase you
have been playing with them.

I did that once (before my total reinstall) except I put  the framework on top of
VS.NET ... worked fine.
The installs are identical as far as I can tell.

Maybe some components  are updated in one or the other, just patch up whatver you
end up with.

Make sure when you do install  VS.NET then copy your samples straight on top of
them.

I would just go ahead and slam it on top - I think it'll be ok. But save your
samples first else changes will be overwritten.

Make sure you specify the same directories you currently have ... i.e. for
samles and sqlserver etc. It should be alright.
