In a nutshell, Query Notification allows you to cache data and be notified when the data has been changed in SQL Server. Upon notification, you can then refresh your cache or take whatever action you need to.

I hope you will find it useful :)

Recently I visited Toronto for Beta release of software I designed. As always with Beta versions, we encountered several problems. The One I want to share with you is related to the CAS and Sandboxed applications. We had an executable located in a shared location on the intranet.
