What is .NET Core?

.NET Core is a new platform

• Cross platform implementation

• Windows

• Linux distributions

• Mac

• Current support for x64 CPUs

• X86 supported on Windows

• ARM64 and ARM32 in progress

What is .NET Core?

• Bias towards platform agnostic

• Console and ASP.NET models today

• Open Source

• Contribute to code or documentationhttps://github.com/dotnet

• Language Support: C# and F# now

What is .NET Core?

Introducing .NET Standard - http://bit.ly/2pEk7bI•

We already have many “.NETs”

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

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 for Windows.
