c# - Prevent memory leaks in WPF

Question

Working with WinForms you have to free memory after using gdi objects, event handlers, objects from native code, etc.

In WinForms I used to remove for example event handlers in the dispose method.

What is the best workaround to prevent memory leaks in Wpf? Is it the same as in Winforms using Dispose pattern? At all, do I have to care about event handlers, gdi objects in Wpf? What about the runtime created resources(Brushes, etc)?

This blog post lists the most common situations that cause memory leaks in WPF applications.

• Event handlers to objects in parent windows
• Registering to events from static objects
• Using timers
• Data binding
• Changing the Text property of a text box

It also describes how to fix these common issues.

Another good approach is to develop an app while following the standard guidelines and then use some kind of profiler to determine any memory leaks or performance bottlenecks.
