.NET MAUI Performance Optimization

Profiling

• dotnet-trace: Cross-platform profiler for all MAUI targets. Collect traces with:

  dotnet-trace collect --process-id <PID> --providers Microsoft-DotNETCore-SampleProfiler
  

• PerfView (Windows only): Use for deep allocation and CPU analysis on WinUI targets.
• Profile before optimizing — measure, don't guess.

Compiled Bindings

• Always set x:DataType on pages/views to enable compiled bindings.
• Compiled bindings are 8–20× faster than reflection-based bindings.
• Required for NativeAOT and full trimming — reflection bindings break under trimming.
• Apply x:DataType at the highest reasonable scope (page or root element).
