What diagnostic tools does this skill recommend?

It guides users through using Visual Studio Diagnostic Tools for snapshots, JetBrains dotMemory for retention paths, and PerfView for GC and allocation analysis.

How does this skill help identify WPF memory leaks?

It provides specific patterns to identify and fix common leak sources such as static events, CompositionTarget.Rendering subscriptions, and DispatcherTimers that aren't properly stopped.

When should I use this Claude Code Skill?

You should use this skill when you observe increasing memory usage in your WPF app, when implementing shared resource dictionaries, or during a performance-focused code review.

Can this skill help with image-related memory issues?

Yes, it includes patterns for using BitmapCacheOption.OnLoad to ensure images are loaded into memory immediately so that underlying file streams can be closed.

What is the Freezable pattern and why is it included?

The Freezable pattern allows UI resources to become read-only, which improves performance by reducing overhead, enabling thread safety, and allowing better GPU utilization.

Developer Tools

Optimizes WPF application performance by implementing memory-efficient patterns and identifying common leak sources.

About

The WPF Memory Optimization skill provides specialized guidance for managing the memory footprint of Windows Presentation Foundation applications. It equips Claude with the technical patterns necessary to implement the Freezable pattern for GPU optimization, resolve chronic memory leaks in event handlers and DispatcherTimers, and optimize image resource loading. This skill is essential for developers debugging memory growth, handling high-frequency UI updates, or building resource-intensive desktop interfaces that require long-term stability and performance.
