The new .NET framework is modern, lean, modular and open source. No longer is .NET a system-wide installation – it is merely a folder. Instead of a huge underlying framework, you only pick and choose the pieces of the .NET framework that you need in your apps. And more importantly, you can package the required components of the .NET framework right alongside your app. We’re entering an age of app-runtime silos and ultimate portability. 

Docker lets you build and run apps, more quickly, with less hardware. That’s why application container technology (and Docker in particular) is so popular. You can run hundreds of containers on a server which could only run a handful of VMs, and containers are fast to deploy and can be versioned like the software they run. 

Why Microsoft's .NET Core is the future of its development platform
