I'd like to be able to detect if the client disconnects (through user initiated shutdown, unhandled exception or loss of network connectivity) so that the server can choose to cancel the expensive request.

With a WCF built on top of a DB containing around 200 tables and Entity Framework, it takes lot of time (around 2 mins) to perform login the first time after building the WCF. Stepping into the code revealed the IQueryable.Count method to be the culprit. This happens only the first time after building the WCF code. Consecutive executio...
