Ribbon-UI Control Part of a future release with other controls and style templates New Controls Web Browser, Ribbon and DataGrid Performance Enhancements Greatly improved cold start time >15% cold start gains for small apps >35% cold start gains for large apps XBAP cold start improvements (real + perceived) ~10% faster XBAP cold start in addition to gains above by improving the concurrency of the ClickOnce download sequence Instant (HTML) download progress UX to improves perceived XBAP startup Performance Enhancements

Splash Screen to improve perceived startup for Standalone apps New public SplashScreen Intuitive VS integration (3 clicks to enable) “Add / New Item…/SplashScreen (WPF)” Sample code available for existing apps or for downlevel targeting

Downloadable VS Template from WPF Futures (www.codeplex.com/wpf) Perf Tools Snoop Generally useful to understand your app, view element tree. WPFPerf Suite Perf “power toy”, a set of diagnostic tools Visual Studio Profiler Great for CPU profiling VS Developer Edition and VS Team Suite CLR Profiler for .NET Shows managed memory usage and leaks Perf Tools Snoop Use to understand the size of the app Visual tree Useful to detect Virtualization related issues & large app trees Perf Tools Snoop Customer app lessons learned: Watch for conditions that may turn virtualization off: • Make sure ScrollViewer.CanContentScroll=True • Make sure VirtualizingStackPanel.IsVirtualizing=True • Keep VirtualizingStackPanel as your default panel …or write own virtualized panel. • Avoid Grouping # of elements can grow also when using rich templates Use Snoop to watch element count Perf Tools WPF Perf Suite Available for external download (WPF SDK & forums) Initial diagnosis of over-invalidation & software rendering A set of tools: Perforator: Analyzes general rendering behavior Visual Profiler: Provides breakdown of an object's use of WPF services, such as rendering and layout String profiler (new): Analyzes where strings are being allocated Event Trace: Analyze events and generating event log files Trace Viewer: Record, display, and browse ETW log files in a WPF user-interface format Perf Tools WPF Perf Suite: Perforator To detect low perf b/c SW rendering: Tint SW rendering: Draws purple when falling back to SW (or when SW used, old driver, card, layered windows on XP, etc) # SW Render Targets: If not 0, significant perf problem (old card, layered windows on XP) # HW Render Targets: # should be equal to the number of app windows times # of display adapters. Indicates app running in HW Low perf indicators Large # of Intermediate Render Targets: additional images that WPF needs in order to get content ready for drawing Maximum SW/HW IRTs per Frame: Shows max # of surfaces needed to render any one frame of the application. Usually caused by the use of DrawingBrush, VisualBrush, Opacity, or Tile modes on a TileBrush. If # high (e.g. > 7), indicates a potential perf issue Perf Tools - Perforator Perf Tools WPF Perf Suite: Visual Profiler Inspect the Visual Tree Show “hot path” of layout time: Tints the elements in the tree based on their time spent in layout Shows inclusive/exclusive times and element counts History graph of time breakdown: Helps identify whether an application’s bottlenecks lie in layout, rendering, animation, etc Perf Tools - Visual Profiler Perf Tools ETW Event Trace & Event Trace Viewer Useful to view low-level WPF ETW events. WClientUceNotifyPresent: Use to calculate frames-per-second rendering perf (e.g. during animation, video, etc) WClientLayout: Use to calculate time app spends in laying out controls (e.g. during resize)

Can also use Xperf/Xperfinfo photoSuru WPF 3.5 Application Running Snoop on photoSuru References
