As far as I can tell, SQLDepedency is just a high level wrapper around SQL Server Query Notifications - you could (if someone hasn't done it already) create such a high level wrapper yourself, or just build what you need on the core services themselves. Instead of Google'ing "SQLDependency", try instead "SQL Server Query Notification".<br>
<br>These articles in particular may be useful:<br><br><a href="http://msdn.microsoft.com/en-us/library/ms130764.aspx">http://msdn.microsoft.com/en-us/library/ms130764.aspx</a><div><a href="http://www.simple-talk.com/sql/t-sql-programming/using-and-monitoring-sql-2005-query-notification/">http://www.simple-talk.com/sql/t-sql-programming/using-and-monitoring-sql-2005-query-notification/</a><br>
<br>You will note that there is quite a bit of infrastructure required in the DB itself to get this stuff up and running and there are some quite specific conditions that have to be met by the query itself - it's not just a case of "notify me about this query". At the very least you need a queue and Service Broker to be running. Whether you are in a position to put that infrastructure in place may determine whether or not this approach is even viable in your case.<br>
