- 2. The .NET 6 Vision One .NET from Desktop, to Web, Mobile, and Beyond!
- 3. The Journey to One .NET • .NET now looks back at a history lasting two decades… • …with many twists and turns • .NET Framework, .NET Core, Mono, Xamarin, UWP, Silverlight, Windows Phone,… • Different components, project structures, APIs,… • .NET 6 completes the journey to reunification of the .NET platform • The goal is to get away from worrying about “what runs where” and simply “targeting .NET” with code that runs everywhere
- 4. NET 5 vs. .NET 6 • . Originally, .NET 5 was supposed to be “One .NET”… • …but Covid (and probably a few other things) made that impossible • In a way, many of the things I will say for .NET 6 today, you may have heard in similar fashion for .NET 5 • .NET 6 brings us full circle and provides the full vision for “One .NET” • .NET 6 is the LTS (Long Term Support) version of the current generation of .NET
- 5. .NET Timeline/Roadmap • .NET 5 Release: November 10th, 2020 • .NET 6 Release: November 9th, 2021 • Annual, predictable releases (started with .NET Core 3.1) • Minor Releases if needed
- 6. GA/Current vs. LTS • Current versions (GA) are supported 15 months • (3 months after the next version’s release date) • LTS versions are supported for 3 years • It should be easy to update from GA to LTS versions
- 7. • .NET Framework 4.8 is the last major version of .NET Framework on Windows • Support policy remains the same: • Will always be in Windows • Will be patched with Windows • Will be supported with Windows • You can keep existing applications on .NET Framework The Future of .NET Framework

- 19. • .NET aims to re-introduce the experience of publishing small, self-contained version of applications • Across all .NET application formats (Windows, Web,…) • Across all the platforms (Windows, Mac, Linux) • Required Framework components are included in the deployment • True xcopy-enabled, single-file executables • Assembly Trimming • .NET has come a long way for this Single File Applications
- 20. • .NET has many performance and size optimizations specifically driven by support for ARM chips • ARM chips are very popular in phones, but they are also becoming more popular in laptops • Surface Pro X is ARM-based • Apple has announced that their future Apple Silicon-based Macs will be ARM based • IoT devices are often based on ARM chips • Raspberry Pi 3 & 4 are ARM-based ARM64

- 23. WinUI 3 • Continuation of WinRT, XAML Islands,… • Windows 10/11 only • Currently available as a preview WinUI 3 is the next generation of the WinUI framework. It dramatically expands WinUI into a full UX framework, making WinUI available for all types of Windows apps – from Win32 to UWP – for use as the UI layer.
- 24. • This is the former “Project Reunion” • Re-unification of various Windows/Desktop UI technologies • WinForms, WPF, UWP, WinUI, Xamarin Windows App SDK The Windows App SDK is a set of new developer components and tools that represent the next evolution in the Windows app development platform. The Windows App SDK provides a unified set of APIs and tools that can be used in a consistent way by any desktop app on Windows 11 and down- level to Windows 10, version 1809. The Windows App SDK does not replace the Windows SDK or existing desktop Windows app types such as .NET (including Windows Forms and WPF) and desktop Win32 with C++. Instead, the Windows App SDK complements these existing tools and app types with a common set of APIs that developers can rely on across these platforms.
