Common performance anti-patterns in .NET MAUI apps are examined with practical fixes. The eight patterns covered include: deeply nested layouts (prefer Grid over stacked StackLayouts), wrapping CollectionView in ScrollView which disables virtualization, blocking the UI thread with synchronous calls, loading oversized images without downsampling or caching, using reflection-based bindings instead of compiled bindings with x:DataType, memory leaks from unsubscribed event handlers and undisposed objects, triggering excessive UI updates by adding items one-by-one to ObservableCollection, and making performance judgments based on debug builds instead of profiling release builds on real devices. Each anti-pattern includes before/after code examples and a brief explanation of the performance impact.
