3. Agenda
• A Brief History of Microsoft .NET
• Explore Developer Experience Outside of Windows OS
• Demystify .NET in Docker and Containers
• Level 300: .NET and Docker hands on Demos
• Your AWS Service Adoption Options

4. Let’s talk about Microsoft .NET

5. Multi Language VM – Microsoft .NET
(Common Language Runtime)
• Launched with Support of 23 Programming Languages
• Languages such as Pascal, Haskel, Cobol, VB.NET, C#, J#/Java, etc
• Designed to Abstract Windows 32 API and COM
• Simplification of Windows Development which was a “Black Art” at the
Time
• Visual Studio .NET IDE Launched as the Primary Developer Experience

6. .NET and Open Source Efforts
• MSFT Shared Sourced and ECMA standardised .NET
• Shared Source Common Language Infrastructure (SSCLI) codenamed Rotor
• Not Licensed to be Used Commercially
• It didn’t go very far Outside of Academia and Research
• Then Mono Came Along…
• Took the great ideas of .NET CLR and Rotor and Rebuilt it from Scratch
• Made it Multi-platform (OSX and Linux - and Windows)
• And Mono-touch made it Cross Device (iOS and Android)
• Added Support for Visual Studio / MonoDevelop (and XCode)
• Now (2016) Microsoft has acquired Xamarin

7. .NET and Open Source Efforts (2)
• Roslyn Released – .NET Compiler Platform Tools
• Set of open-source compilers and code analysis APIs for C# and Visual Basic .NET
languages
• Microsoft Decided to go Full Open Source with .NET Runtime
• Announced and Released .NET Core CLR
• Cross platform run-time support for .NET applications + ASP.NET Core
• Docker support announced for Windows Developers
• MSFT and 3rd Party Projects at www.dotnetfoundation.org
• Aims to take Open Source Community Projects to the Next Level

8. ASP.NET Core and CoreCLR Cross Platform
• Premiere Developer Experience on Windows (still)
• Predominantly GUI and now more command line centric
• Now Developers can edit in Visual Studio Code, Sublime, emacs with
intellisense and tools extensions on OSX and Linux
• Learn more from http://www.omnisharp.net
• Command Line Experience same across All Platforms (CLI)
• Windows, OSX and Linux Variants
• Enables true Automation, continuous Integration and Delivery (CI/CD)

9. Visual Studio Code on Mac OSX
Visual Studio Code
A Mini-Visual Studio IDE Development Environment for Cross Platform Development

10. Your .NET Framework and Runtime Options
• (Classic) .NET Framework – Windows Only and Feature Complete
• .NET Core CLR – New Microsoft Cross Platform Runtime
• Feature Complete now in Stabilisation Phase (RC2)
• Linux and OSX in-progress RC2 builds (Ubuntu, Centos, FreeBSD, OSX, SuSe)
• Available on Git: https://github.com/dotnet/coreclr
• Mono – 3rd Party Cross Platform and Open Source
• Similar APIs to .NET Framework with high level of compatibility

11. Developer Experience

12. Porting to .NET Core
• Apiport – .NET Portability Analyser
• Source available on Git: https://github.com/Microsoft/apiport
• Console and Visual Studio Versions: https://dotnet.github.io/porting/
• MSDN: Porting MSBuild to .NET Core: http://bit.ly/1QyFVaX

13. What’s the Difference Between Runtimes?
(And why should I care?)
• .NET Core – No longer large monolithic core Framework libraries requiring whole assembly
redeployments – instead lots of little packages are used
• Using Popular NuGet Package Format Used – extend the application and runtime support libraries
• Some Common (60+) Projects at https://github.com/aspnet
System.Core.File
System.Core.IO
System.Web.Session
System.Web.SignalR
MyApp.Service MyApp.Libs1
MyApp.LibsNMyApp.API
System.Web
System.Core
MyApp.Everything

14. Let’s talk about Docker & Containers
☐✔

15. How is Docker Different from VMs?
Containers have similar resource isolation and allocation benefits as virtual
machines but a different architectural approach allows them to be much more
portable, light-weight and efficient.

16. About Containers…
• Include the Application and all of its Dependencies
• Share the Kernel with Other Running Containers
• Run as an Isolated Process in user space on the Host Operating
System
• Not Tied to any Specific Infrastructure – Docker Containers run on
Any Computer, on Any Infrastructure such as the AWS Cloud
• Popular in Linux World and Now Available to .NET Developers
(thank MSFT)

17. Why It Matters to Microsoft Applications?
• For Existing Applications
• Move your existing .NET applications into highly portable self-sufficient
containers
• Extend the life of applications or merely renovate them
• For Green Field Applications
• Develop brand new applications using ASP.NET Core/.NET Core
• Develop via Visual Studio (Windows) or Visual Studio Code (OSX/Linux) or CLI
• Press a button or run a script to deploy it into Docker on AWS
• Bring your applications into a modern and agile (CI/CD) DevOps world
• Move into AWS – Gain Agility, Cost Reduction and Mass-Scale Out

18. Hands on Demos…

26. How Does AWS Support .NET & Docker?
Option 1: Roll Your Own
• Run Docker on EC2
• Something you may have already tried to do on your local development PC
Option 2: Use Rapid Deployment Services
• Use the AWS ElasticBeanstalk Service which natively supports both Docker and
Windows IIS
• Great for developers wishing to get started quickly with low interest in the
underlying infrastructure
Option 3: Use Docker as a Service
• Use the AWS EC2 Container Service (ECS) with full native Docker support
• Great for engineers who want full access to the underlying core infrastructure

27. In Summary:
1. Microsoft is Making Cross Platform Development Easier
2. The .NET Core Runtime has been Open Sourced
3. Existing .NET and Greenfield Applications can run in
Docker
• Under Mono and .NET Core run-time environments
