Deploy an ASP.NET container to a container registry using Visual Studio

  • Article

Docker is a lightweight container engine, similar in some ways to a virtual machine, which you can use to host applications and services. This tutorial walks you through using Visual Studio to publish your containerized application to an Azure Container Registry.

If you don't have an Azure subscription, create a free account before you begin.

Prerequisites
