This document provides an introduction to .NET Core, ASP.NET Core, and .NET Standard. It explains that .NET Core is a cross-platform version of .NET that is open-source and has a smaller footprint than the full framework. ASP.NET Core is the next generation of ASP.NET that is modularized, faster, and cross-platform. It uses a pipeline and middleware approach. .NET Standard defines a common language specification that both .NET Core and other platforms can implement, allowing libraries to run on multiple platforms. The document outlines how to get started with these technologies.
Intro to.net core 20170111
- 1. INTRO TO .NET CORE .NET CORE, ASP.NET CORE, NETSTANDARD, RUNTIMES
- 2. AGENDA • WHAT IS .NET CORE? • WHAT IS ASP.NET CORE? • WHAT IS NETSTANDARD? • GETTING STARTED
- 3. WHAT IS .NET CORE?
- 4. WHAT IS .NET CORE? A VERSION OF .NET THAT: • IS X-PLATFORM • FLEXIBLE DEPLOYMENT • OSS • COMMAND LINE FIRST TOOLING • SMALLER THAN, BUT COMPATIBLE WITH FULL FRAMEWORK
- 5. WHAT IS .NET CORE? WHAT ARE THE COMPONENTS? UWP Apps | Console Apps | Web Apps CoreFx (BCL) Runtime Adaption Layer .NET Native | CoreClr
- 6. WHAT IS .NET CORE? WHAT ARE THE COMPONENTS? UWP Apps | Console Apps | Web Apps CoreFx (BCL) Runtime Adaption Layer .NET Natvie CoreClr
- 7. X-PLATFORM • WINDOWS • DESKKTOP • SERVER • NANOSERVER • LINUX • RED HAT ENTERPRISE LINUX • UBUNTU • DEBIAN • FEDORA • CENTOS • OPENSUSE • MAC
- 8. FLEXIBLE DEPLOYMENT NOT IN GAC
- 9. FLEXIBLE DEPLOYMENT App 1 .NETCore v. X App 2 .NETCore v. Y App 3 .NETCore v. Z
- 10. FLEXIBLE DEPLOYMENT App 1 App 2 App 3 .NET Core installed on server
- 11. SMALLER FOOTPRINT …MAYBE: • OPT-IN THROUGH NUGETS • OR GO WITH .NETCOREAPP • * SEE ASP.NET CORE INTRO :)
- 12. COMMAND LINE – WHY? • AUTOMATION • CROSS PLATFORM • VISUAL STUDIO INDEPENDENCE • WELL WORTH LEARNING
- 13. ps> dotnet
- 14. OSS / OWNERSHIP / SUPPORT • EVERYTHING ON GITHUB • MIT LICENSE (CORECLR, COREFX, CLI), APACHE (ROSLYN, ASP.NET) • OWNED AND GOVERNED BY MICROSOFT • ACCEPTS CONTRIBUTIONS
- 15. BONUS: PROJECT SYSTEM MODERNIZED CSPROJ • EDITOR / HUMAN FRIENDLY • FRAMEWORK TARGETS • APP MODEL • NUGET DEPENDENCIES • CAN BE USED WITH FULL FX <Project ToolsVersion="15.0" xmlns="http://schemas.microsoft.com/dev <Import Project="$(MSBuildExtensionsPath)$(MSBuildToolsVersion)M <PropertyGroup> <OutputType>Exe</OutputType> <TargetFramework>netcoreapp1.0</TargetFramework> </PropertyGroup> <ItemGroup> <Compile Include="***.cs" /> <EmbeddedResource Include="***.resx" /> </ItemGroup> <ItemGroup Condition=" netcoreapp1.0"> <PackageReference Include="Microsoft.NETCore.App" Version="1.0.1 <PackageReference Include="Microsoft.NET.Test.Sdk“ Version="15.0 <PackageReference Include="xunit" Version="2.2.0-beta3-build3402 <PackageReference Include="xunit.runner.visualstudio" Version="2 </ItemGroup> <Import Project="$(MSBuildToolsPath)Microsoft.CSharp.targets" /> </Project>
- 16. ASP.NET CORE
- 17. HIGHLIGHTS • MODULARIZED • FAAAAAASSSST • PIPELINE, MIDDLEWARE • UNIFIED MVC AND WEBAPI • OSS • .NET CORE BASED • CROSS PLATFORM • COMMAND LINE • SIDE-BY-SIDE DEPLOY • LESS DEPENDENT ON VISUAL STUDIO
- 18. ASP.NET TODAY IIS .NET BCL ASP.NET ASP.NET MVC ASP.NET Web API HTTP Modules ASP.NET WebForms HTTP Handlers Request pipeline HTTP Context et al. Caching Session State
- 19. ASP.NET CORE – GUIDING PRINCIPLES • NO DEPENDENCY ON SYSTEM.WEB • THIS IS HUGE • CROSS PLATFORM • LOW FRICTION (THIS IS MY INTERPRETATION)
- 20. ASP.NET – THINGS NOT IN CORE IIS .NET BCL ASP.NET ASP.NET MVC ASP.NET Web API HTTP Modules ASP.NET WebForms HTTP Handlers Request pipeline HTTP Context et al. Caching SessionS tate
- 21. ASP.NET – AND THINGS CHANGED IN CORE IIS .NET BCL ASP.NET ASP.NET MVC ASP.NET Web API HTTP Modules ASP.NET WebForms HTTP Handlers Request pipeline HTTP Context Caching SessionS tate
- 22. ASP.NET CORE Kestrel .NET Core | Full Fx ASP.NET Core ASP.NET MVC (WebApi, Razor)
- 24. DEPLOYMENT MODEL Reverseproxy IIS/NGINX Kestrel .NET Core ASP.NET Core ASP.NET MVC (WebApi, Razor)
- 25. ASP.NET CORE: PIPELINE • USE PIPES AND FILTERS • A CONTEXT IS PIPED THROUGH MIDDLEWARE 25
- 26. ASP.NET CORE: PIPELINE 26 Kestrel Application
- 28. MIDDLEWARE • MIDDLEWARE TRANSFORMS THE REQUEST AND RESPONSE • TAKES A CONTEXT IN • CAN CALL NEXT STEP IN PIPELINE • OR NOT • UNIFORM INTERFACE • COMPOSABLE , REARRANGEABLE 28
- 29. MIDDLEWARE • 2 TYPES • OWIN • ASPNET CORE 29
- 30. OWIN: MIDDLEWARE ECOSYSTEM • SECURITY: • OAUTH, TWITTER, FACEBOOK, GOOGLE, … • CLAIMSTRANFORMATIONS • REQUIRESSL • SCOPEVALIDATION • … • WEB: • ROUTING • LIMITS • SITEMAP • STATICFILES • MONITORING • RAYGUN • SERILOG • … 30
- 31. .NET STANDARD
- 32. .NET STANDARD “TO PROVIDE A MORE CONCRETE GUARANTEE OF BINARY PORTABILITY TO FUTURE .NET-CAPABLE PLATFORMS WITH AN EASIER-TO-UNDERSTAND PLATFORM VERSIONING PLAN.”
- 33. .NET STANDARD VS PCL • PCL STATES PLATFORMS • PORTABLE-NET45+WP80+WIN8+WPA81 • .NET PLATFORM STANDARD • LIBS STATE REQUIRED MINIMAL API LEVEL • PLATFORMS STATED IMPLEMENTED API LEVEL • NETSTANDARD1.3 • FORWARD COMPATIBILITY
- 34. .NET STANDARD • CHOOSE API LEVEL • COMPILE AGAINST REFENCE .DLLS • RUN AGAINST TARGET DEPENDENT IMPLEMENTATIONS 34
- 36. GETTING STARTED
- 37. GETTING STARTED • BOTTOM UP • PORT LOWEST LEVEL LIBS TO .NET PLATFORM STANDARD 1.6 • PORT OWIN MIDDLEWARE AWAY FROM KATANA • (USE LIBOWIN INSTEAD) • BUILD SERVER => NUGET PACKAGES
- 38. GETTING STARTED • FIND A LOW IMPACT SERVICE, USE IT TO DRIVE • PROD ENVIRONMENT • DEPLOYMENT PIPELINE
- 39. GETTING STARTED • WHEN? • .NET CORE AND ASP.NET CORE ARE 1.1 NOW • TOOLING IS PREVIEW NOW • Q2 2017: • TOOLING RTM • .NET CORE 2.0 (FASTER) • .NETSTANDARD 2.0 (LOTS AND LOTS OF APIS) • ASP.NET 1.2 (SIGNALR, FASTER, SECURITY)
- 40. GETTING STARTED • FOLLOW ULTRA SHORT TUTORIAL HERE: HTTPS://WWW.MICROSOFT.COM/NET/CORE#WINDOWSCMD • MORE INFO HERE: HTTPS://DOCS.MICROSOFT.COM/EN-US/DOTNET/ARTICLES/CORE/ • BUT YOU TO DIG DEEP … YOU STILL GO TO GITHUB
- 41. WRAP UP
- 42. WHY DO I CARE? • DOTNET CLI AND CROSS PLATFORM: • USE LINUX IN PRODUCTION • BROADER POTENTIAL DEVELOPER CROWD • DOTNET AS ENABLER FOR YOUR OWN TOOLING • DOTNET AS ENABLER FOR 3RD PARTY / OSS TOOLING
- 43. WHY DO I CARE? • MODULARIZED .NET SMALLER FOOTPRINT ON DISK AND MEMORY (!) FASTER DEVELOPMENT FROM MS ON SOME PARTS SIDE-BY-SIDE ON DIFFERENT VERSIONS
- 44. WHY DO I CARE? • MIDDLEWARE NICE MODULAR WAY OF WORKING SEPARATION OF INFRASTRUCTURE AND APPLICATION • MORE OWIN BETTER OPPORTUNITY FOR .NET OSS OWIN MIDDLEWARE ECO SYSTEM WILL BLOSSOM NICE MODULAR WAY OF WORKING
- 45. WHY DO I CARE? • MVC UNIFIES MVC AND WEBAPI PROPERLY MOVES CLOSER TO “MODERN” FRONTEND DEVELOPMENT
