upgrade to .NET 2.0

[CSharpguy]

I currently have a web project in .NET 2003 and it uses datalayer, business
layer classes. I want to start upgrading the projects to .NET 2005 (2.0). If
I do my business layer and datalayer in 05 can I still connect and use the
class (dll) from my .net 2003 projects?

No,

You can go the other way, but not that way.

Your presentation layer in 2.0 can talk to 1.1 biz layer.

But you can't have a 1.1 presentation talking to 2.0 biz objects.

At least thats my experience. I"m sure others will chime in with more
concrete info.
