3 .NET Framework and Tools Roadmap 2006.NET Framework 3.0 VS 2005 Extensions for.net 3.0 (CTP) 2007.NET Framework 3.5 Visual Studio 2008 Expression Blend NET Framework 3.5 SP1 Visual Studio 2008 SP1 Expression Blend 2.0

4 .NET Framework Roadmap.NET Framework 3.5 SP1 WPF Enhancements Other Enhancements (ASP.NET, etc.).net Framework 3.5 WPF 3.5 LINQ Add-in Framework WF & WCF Enhancements.NET Framework 3.0 WPF WCF WF CardSpace CLR.NET Framework 2.0 Base Class Library WinForms/ ASP.NET

5 WPF in a nutshell Rich Windows Applications Great Architecture + Great Graphics Rapid Prototyping 2D, 3D, Vector, Document Flow, Layouts, Composition, etc.

6 WPF 3.5 Enhancements.NET Framework Client Profile ~25MB client subset of.net Framework Customized install experiences Deployment Interactive 2D on 3D Pixel Shaders and Effects Model DirectX Interop New Controls Graphics Cold Startup Improvements Several perf enhancements Profiling tools and instrumentation Performance

7 .NET Client Profile ~25MB Client-only Subset of.net Fx Includes WinForms, WPF, LINQ, etc. Excludes ASP.NET, WCF, etc. 200KB fully customizable Bootstrapper

8 .NET Framework Client Profile Using the Client Profile Deployment option in Visual Studio 2008 SP1

9 WPF 3.0 Graphics Recap Rich set of 2D drawing primitives Basic 3D functionality via Viewport3D Rich Media Integration Extensive Animation System Advanced Text Stack Bitmap Effects Imaging Compositor

10 WPF 3.5 Graphics Enhancements True Interactive 2D-on-3D Pixel Shaders Effects Model Hardware-Accelerated HLSL Support DirectX Interop Interop Bitmap Replaces Writeable Bitmap Faster Layered Window Support Animation Fixes

11 Graphics Enhancements Interactive 2D on 3D Pixel Shader Effects

12 New Controls Web Browser Control Interop between HTML and WPF content WPF -> HTML WPF application can call script methods in HTML with WebBrowser.InvokeScript HTML -> WPF Script in HTML can call methods and access properties on WebBrowser.ObjectForScripting that are COM- Visible with window.external Load hosted HTML content from a stream or string Access the document object loaded in the WebBrowser

13 New Controls DataGrid Control Available from WPF Toolkit ( CTP Release with several features, being further improved upon Ribbon-UI Control Part of a future release with other controls and style templates

14 New Controls Web Browser, Ribbon and DataGrid

15 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

16 Performance Enhancements Splash Screen to improve perceived startup for Standalone apps New public SplashScreen APIs 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 (

17 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

18 Perf Tools Snoop Use to understand the size of the app Visual tree Useful to detect Virtualization related issues & large app trees

19 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

20 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

21 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 api 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

22 Perf Tools - Perforator

23 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

24 Perf Tools - Visual Profiler

25 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
