Sharing Logic Between Windows Forms And Web Forms

[Skinsey]

I've been developing asp.net applications for many years now and I need to start creating some windows forms which is a new area for me.

My question is, am I able to share a business logic layer seemlessly between the two presentation layers or is there anything I need to watch out for. I'd really like to not have any duplication of business logic, so any advice would be more than welcome.

I am working on .Net 2 and Studio 2005. Would I have any big advantages in migrating to 3.5 with this?

Thanks
