Hello Francesco:
Your Design Pattern Framework 4.0 purchase includes older versions of the Framework as well. These include versions for .NET 3.5, .NET 2.0, and .NET 1.1.
Of course, the more recent versions are 'richer' and have more functionality, simpley because .NET is richer. But the fundamentals of what Design Patterns are and how they are used has not changed -- in fact, Design Patterns already existed before .NET.
I hope this helps.
Dan.
