Deploy ASP.Net Core apps to Azure App Service

In this article we will learn about How to Deploy ASP.Net Core apps to Azure App Service. Microsoft Azure provides many services for hosting web applications, and Azure App Service is a major type. It is an HTTP-based service that we can use to host web applications, REST APIs, and mobile apps. Please read my previous article about Deploy ASP.NET Core Web App in Azure Virtual Machine.

What is Azure App Services?

Azure App Service is an HTTP-based service for hosting web applications, Rest APIs and mobile back ends, you can develop in your known language using .Net, .Net core, Java, Ruby, Node.JS, PHP, and Python. Asp.net core applications run and scale with both Windows and Linux-based environments. In this article, you will learn more about how to create web apps using asp.net core and publish applications into Azure.

Prerequisites

– Create new Account / Login Azure.
– Visual Studio 2019/2022

Signing up with the Azure Portal

We need to have an active Azure subscription to start using the Azure services. However, we can sign up for a free account after navigating to the Azure Portal (https://portal.azure.com/) if we do not have an account. A free account will come with an essential subscription, which gives us access to many services. Some of the Azure services are free for life, while some others are free for a limited time.

The Azure portal is a web-based, unified console using which we can build, manage, and monitor the Azure resources. Once we log into the Azure portal, we can see the Home page like below:

Creating an App Service

There are different types of App Services and we can choose the appropriate one based on our need.

• Web App is the best choice for hosting websites and web applications.
• We can use API App for hosting RESTful APIs. If we need to host mobile app back ends, we have Mobile App.

We can create an App Service from the Azure portal, or we can do it from Visual Studio while deploying our application. In this article, we are going to learn how to create an App Service directly from Visual Studio while we publish a web application.

When navigating to Azure App Service we can see there is no App service is hosted till yet in my account.
