Web or Windows forms [RESOLVED]

Question

When .NET came out, Web Forms and Windows Forms targeted two different scenarios: Web and Desktop

I wonder if now (with Framework 4 and VB 2010) this is still true or not. In other words, if I plan to program a new application, I must have in mind how EVERY form will be used : only desktop, only internet or both, and decide on a case by case basis how it is developped: Windows Forms or Web Forms.

I would like to receive some advice on that.

thanks
