Find memory leaks and optimize memory usage in your .NET application
Automatic memory management in .NET makes development a lot easier, but it's still easy to introduce memory leaks into your application. For example, forgetting to unregister event handlers can lead to significant chunks of memory being held on to unnecessarily, but spotting that this is happening can be very difficult.
Trying to understand memory problems without a suitable tool can take hours or days, if you're lucky enough to know a problem exists. This is time which would be better spent fixing the problem.
