7. Argument with dev friend who hates MS!

9. Any Developer. Any App. Any Platform.
• Radical shift to embrace everything open and community based.
• .NET: written anywhere and run anywhere
• Influential people

10. .NET Siblings
1. .NET Framework 4.6.*/4.7.*: This continues to be the next iteration of the
existing mature .NET Framework. Supports entire API canvas and a variety of application
platforms. Windows only.
2. Mono 4.6.*: Open source development platform based on the .NET Framework and
the ECMA standards for C# and the Common Language Infrastructure (CLI).
3. .NET Core 1.*/2.*: New lean modular cross-platform and open source version
of .NET, written from ground up, .NET Core is optimized for specific runtimes and runs on
any platform.

11. .NET Core

12. Compared to Elder Brother

14. .NET Unified Platform

15. .NET Standard Spec

18. ASP.NET Core
• Complete new open-source and cross-platform framework for building
modern cloud based web apps, IoT apps and mobile backends.
• Runs on .NET Core or on the full .NET Framework.
• Pushes the framework forward with improved modularity, cross-platform
adoption and web standardization.
• Ships entirely as NuGet packages.

20. ASP.NET Core - Kestrel
Kestrel is a cross-platform web server for ASP.NET Core based on libuv.
Performance (Techempower benchmark):
• 1.1 with Kestrel ranked as the fastest mainstream fullstack web framework in the
plaintext test.
• Going 2,120 rps on ASP.NET MVC Mono in Round 11 to 1,822,366 rps on
ASP.NET Core in Round 13. Its 85,900% improvement.

21. Universal Windows Platform (UWP)
• App platform for Windows 10 and target device families, not an OS
• One API set, one app package (.appx)

23. .NET Native
• Pre-compilation technology for building UWP apps
• Introduced April 2014, AOT compilation, Generates highly optimized native
machine code.
• No dependencies on the .NET Runtime
• C++ performance with C#/F#
• Up to 60% performance improvement on cold startup times (up to 40% on
warm startup times)
• Less memory consumption when compiled natively

24. Azure
• Cloud computing platform and infrastructure for building, deploying, and
managing applications and services
• It provides SaaS, PaaS and IaaS services and supports many different
programming languages, tools and frameworks

27. Xamarin Platform

28. .NET Dev World Impacts
• AR/VR applications: Using Unity on top of .NET/C#. Several AR/VR
headset manufactures support Unity as a platform to build apps.
• Samsung releases Tizen OS for .NET that allows .NET developers to build
apps for Samsung devices TV, refrigerators, mobiles and other devices.
• Google joins .NET foundation.
• Cross platform is key to the success of .NET. Now, .NET developers can
build pretty much any kind of app they want.
• Microsoft is now platinum member of linux foundation.

29. Github Trends
• JavaScript, C#, and Go who
have almost doubled growth.
• Swift and TypeScript are up and
coming with 3.5x growth.

30. List goes on...
• Visual Studio Code has been a huge success so far with more than 2
million installs
• PowerShell recently made its debut on macOS and Linux
• Microsoft Open Sourced Chakra Core.
• TypeScript and big players are betting on Typescript.
• Free to start cognitive services: vision, speech, language, knowledge, and
search APIs
• Microsoft Offers a Bot Framework and much more...

31. So what does all this mean for .NET developers?
• .NET Core is open source and the community is growing rapidly. More and
more companies and developers are joining .NET Core community.
• The Language of the Future is C# and .NET CLI is developers love.
• Since bulk of changes happening and the speed at which they are delivered,
expect some difficulties along the way.
• So we will enjoy new open development process and transparent roadmaps.

32. Gone are the days of Microsoft secrecy.
Exciting future ahead for .NET, it’s cross
platform, open source, cloud-first and full of app
models.
One would expect from a modern set of tools and
languages.

33. Happy Coding!
