Hi,
DataSets are usually resource heavy. Instead of having to pass them
from my middle tier to my presentation layer I was wondering if anyone
has developed a custom collection object that is less resource heavy
and can be passed lightweight to the presentation layer.
Thanks,

The coupling is currently like this:
