WPF Bindings can actually cause memory leaks. The rule of thumb is to always bind to a DependencyObject or to a INotifyPropertyChanged object. When you fail to do so, WPF will create a strong reference to your binding source (meaning the ViewModel) from a static variable, causing a memory leak (explanation).There are a number of ways to detect this type of leak. The easiest is to capture a snapshot after the object was expected to be released. In the snapshot overview page, we will immediately see if the object remained in memory because of an event handler leak.Start the debug diagnostic tool and select ‘Memory and handle leak’ and click next. Select the process in which you want to detect memory leak. Finally select ‘Activate the rule now’. Now let the application run and ‘Debugdiag’ tool will run at the backend monitoring memory issues.
