You have a Windows Presentation Foundation (WPF) application that uses the Microsoft .NET Framework 3.5 Service Pack 1 (SP1). This application uses the ResourceDictionary class and the MergedDictionaries property to manage resources. When the application removes a resource dictionary for an element, the reference for the element is not removed from the resource dictionary. This results in a memory leak. When you run the application for a long time, memory usage on the computer may increase significantly.
