4. Agenda
•What is .NET Core?
•Acquiring .NET Core
•Development Experience
•Publishing and Deployment Examples

5. What is .NET Core?
.NET Core is a new platform
• Cross platform implementation
• Windows
• Linux distributions
• Mac
• Current support for x64 CPUs
• X86 supported onWindows
• ARM64 and ARM32 in progress

6. What is .NET Core?
.NET Core is:
• Bias towards platform agnostic
• Console and ASP.NET models today
• Open Source
• Contribute to code or documentation
https://github.com/dotnet
• Language Support: C# and F# now
• Visual Basic listed as future support

7. What is .NET Core?
Introducing .NET Standard - http://bit.ly/2pEk7bI
We already have many “.NETs”

8. What is .NET Core?
.NET Core does not:
• Meld into your machine like .NET Framework
• Require in-place upgrade for every “app” running on a server
• Include .NET Core in your app
• Install side-by-side on machine
• Implement everything you remember from .NET Framework
• Example: Code Access Security,WPF, WCF

9. What about .NET Framework?
• .NET Framework 4.6.2 released in August 20161
• .NET Framework 4.7 released in April 20172
.NET Framework continues a framework forWindows.
