Raw threads and async lambdas

Senior Consultant, Ben Williams shares some suggestions on avoiding unexpected behaviors with async/lambdas

Using async methods/lambdas where they are not expected causes unexpected problems. The typical example I discuss with people is TaskFactory.StartNew() because it’s an easy way to create Tasks and some people reach for that instead of Task.Run(), but I recently came across some code hitting the same problem while creating threads the traditional way.

In this scenario, the code was intended to create some child threads that poll a resource. That resource would sometimes be changed and the master thread would Abort() the child threads and create new ones polling the new resource. But there was a thread leak. Sometimes threads could continue to run after they should have been aborted.
