Subject Re: Silverlight, Compact Framework Support
Date Wed, 05 Nov 2008 05:35:07 GMT
Personally, don't understand why not to use LINQ to objects for searches in
collections , unless you save big chunks of text in each object. As for
silverlight applications , aren't they supposed to be rather thin in general
where other layer over net  serves query from Silverlight.
