Use Azure App Service Deployment Slots with Azure CLI

Azure App Service includes deployment slots that help to improve the way in which updates to your code can be deployed to production. In this hands-on lab, we'll use Azure CLI within the Cloud Shell, in order create and use deployment slots for a simple web application. The Cloud Shell includes Azure CLI and the .NET Core CLI, which we will use to perform all tasks. **Scenario** You've recently been employed as a cloud developer, and have been asked to perform a proof of concept using Azure App Service deployment slots. In order to perform this proof of concept, you will need to: * Deploy a simple .NET Core web application to a new Web App in Azure App Service * Make changes to your web application, and deploy these to a staging slot * Perform a slot swap, so that your changes are promoted to production
