VB.NET 2005 to 2008 but still windows 2.0? Image object problem.

[Victory]

Hi,
I just used VS2008 and migrated a project from 2005 to
2008. The reason is that MSDN docs is saying the Image
object in .NET Framework 3.5 has a Finalize method, which i
want to try out since my app is processing a few image
files and then saying it is running out of memory. I am
using the Dispose method of this object to get rid of it
and then setting it to Nothing. in any case, when i used VS
2008, intellisense still does not show the Finalize method
as one of the methods of the object. Any idea why it is
still using the Image object from .net framework 2.0?
Please see code below:
thanks,
Mars
