In this quickstart, youll learn how to create and deploy your first ASP.NET web app to Azure App Service. App Service supports various versions of .NET apps, and provides a highly scalable, self-patching web hosting service. ASP.NET web apps are cross-platform and can be hosted on Linux or Windows. When youre finished, youll have an Azure resource group consisting of an App Service hosting plan and an App Service with a deployed web application.
