If you’re building a new application and have a choice between .NET Core and .NET Framework, .NET Core is the way to go.

.NET Core is better suited for cross-platform needs. .NET Core apps are supported on Windows, Linux, and macOS. Microsoft’s popular open source code editor, Visual Studio Code, is supported on Windows, Linux and macOS. VS Code supports modern needs of code editors including IntelliSense and debugging. Most third-party editors, such as Sublime, Emacs, and VI, work with .NET Core.

Microservices architecture is supported in .NET Core, which allows cross platform services work with .NET Core including services developed with .NET Framework, Java, Ruby, or others.

Containers are the VMs of today. .NET Core’s modularity, light weight, and flexibility makes it easier to deploy .NET Core apps in containers. Containers can be deployed on any platform, cloud, Linux, and Windows. .NET Core works well with both Docker and Azure Kubernetes Service.
