  4. What are we hearing from you? Every company is becoming a software company. Enterprise software needs to be innovative, agile and polished. Line of business apps must be cross-device. Open Source enriches the platform and the community. Enterprises have existing applications to evolve and keep running.

  5. Our investments in .NET Open • .NET is open and community-driven .NET Productive • .NET skills transfer to many scenarios VS SDK Innovative • .NET will continue to be relevant

  6. Session overview • .NET Framework 4.5.1 4.5.2 • ASP .NET vNext and cloud-optimized .NET • Portable Class Libraries & Universal Apps • .NET Native • RyuJIT modern JIT compiler

  7. .NET 4.5.2 available for download • Highly compatible, in-place update of .NET 4, 4.5 • Incorporates feedback from 4.5.1 release • 7 major features, 109 bug fixes • ASP.NET improvements • HostingEnvironment.QueueBackgroundWorkItem • HttpResponse.AddOnSendingHeaders • HttpResponse.HeadersWritten • High DPI rendering improvements in Windows Forms controls DataGridView, ComboBox, ToolStripMenuItem, Cursor • Distributed Transactions enhancements • More robust profiling APIs for better dependency injection • ETW-based tracking on a larger .NET Framework surface area • Improved activity tracing support

  8. .NET Ecosystem Open • Share early and share often Consistent • .NET is .NET, everywhere Feedback • Your feedback drives our work

  9. ASP .NET vNext • New, modular, modern web stack • Ships .NET Framework as part of your web app • Servicing events limited to critical security issues • “Cloud optimized” framework ships with CoreCLR

  10. Making your .NET knowledge more valuable Shipping APIs across platforms on NuGet Improved options for sharing code Feedback-driven • Shipping faster and across more platforms with NuGet • Problems: • Support • Discoverability • Not every core API is portable across platforms (e.g., file) • Portable Class Libraries improved for scalable, cross-device sharing • Universal Projects enable sharing of source and assets • Shipping much more often • Make changes due to UserVoice and bug reports • Using light-weight public previews to collect feedback

  13. Sharing is good • Microsoft NuGet packages and Portable Class Libraries (PCLs) are licensed to work cross-platform • PCLs work in Visual Studio Express & Xamarin tools

  14. Sharing more is better • Portable Class Libraries can depend on WinRT APIs • PCLs can be exposed to other languages as WinMD • WinRT is converging across Windows platforms • Increasing the set of APIs available on all platforms

  15. Universal Windows Apps • Share source & assets between Windows 8.1 and Windows Phone 8.1 platforms • You can even share XAML UI in the designer • Share your project directly—no need to create Portable Class Library binaries • Create an app for both platforms from one project

  16. Universal Windows Apps Conditional constants… #if WINDOWS_PHONE_APP Windows.Phone.UI.Input.HardwareButtons.BackPressed+= this.HardwareButtons_BackPressed; #endif …drive IntelliSense, syntax highlighting, emulators, etc.

  17. http://SourceOf.net • Completely new browsing experience with search and navigation powered by Rosyln • Hyperlinked source code • Browsing features include • Go to definition • Find references • Highlight references • Document Outline • Project Explorer • Namespace Explorer Step through .NET Framework sources when debugging your code Browse .NET Framework source code online

  18. Session overview • Continued investment in full .NET Framework • ASP .NET vNext and a cloud-optimized .NET • Portable Class Libraries & Universal Apps • .NET Native • RyuJIT modern JIT compiler

  19. .NET code generation: A primer MSIL bytecode Source code (C#/VB/F#) Machine code C#/VB/F# compiler Code generation • Code generation is done either…. • Lazily at runtime with a Just-In-Time, or JIT, compiler • Optimistically at build time with NGen, Triton or .NET Native

  20. .NET Code Execution today C++ Performance Self-contained apps Dynamic experience “Unlimited” class libraries

  21. .NET Native (Project N) • Next Generation Compiler in the Cloud builds upon Triton for Windows Phone • Apps compiled with .NET Native start up to 60% faster and use ~25% less memory • Developer Preview available at http://aka.ms/dotnetnative Wordament on .NET Native:

  22. Visual Studio Experience for .NET Native Debug and test your app with .NET Native Enable .NET Native for your project

  23. Just-In-Time (JIT) compilation A compiler’s performance is measured in two ways: • Throughput measures how fast a compiler generates app code. Because a JIT compiler runs before user code throughput dominates startup. • Code quality measures how fast the generated code runs. Code quality matters most in a long-running process where code is JIT compiled once and run for a long time. • 32-bit JIT emphasizes throughput over code quality • 64-bit JIT emphasizes code quality over throughput

  24. RyuJIT performance CTP3 vs JIT64, code quality

  25. RyuJIT is a modern JIT compiler • RyuJIT is based on JIT32 for fast throughput • RyuJIT brings optimizations from JIT64 for great code quality • Having one JIT codebase means faster innovation • First new feature: SIMD in CTP3 • More new features to come including x86 & ARM support • Try out CTP3 today: http://aka.ms/RyuJIT
