How to deploy an Angular CLI application built on ASP.NET Core to Azure using Visual Studio Team Services and Continuous Integration, Visualized

Let’s learn how to deploy the app we just built as an Azure Web App using Continuous Integration. The end goal is to be able to check in a change which will automatically trigger a build and publish the latest code to an Azure Web App.

We’ll be starting where this article left off:


Some Housekeeping for the SuperCoolApp

  1. Remove the Angular build command from your *.csproj
    The angular app will eventually be compiled by a VSTS build agent in the cloud and it’ll handle compiling the Angular code

2. Set deployment retry attempts to 30 in your *.csproj


Create your App Service in Azure

Head to and login

On the left pane, select New
Search for Web App and Create it

Set your name, create a resource group and create an appropriate App Service plan — The F1 (Free) pricing tier will work just fine, but don’t expect blazing fast load times — then create your web app.

Create a Visual Studio Team Services Project

Navigate to the VSTS portal you setup when creating your VSTS account and create a new Project

Note: Version control and Work item process are only applicable if using VSTS to store your code and track your work items, but we’ll be using GitHub as our source repository instead so it doesn’t matter

Create a Build Definition to Deploy Your App

Navigate to your Builds section

Create a new build definition

Select the ASP.NET Core template

Set the Default agent queue to Hosted VS2017

Set the package source to your GitHub repository

Add an npm task, move it to before the Restore task, and clone it

Set the npm task version to 0.*

Set the npm task version to 0.*

Set the working folder to where your project’s package.json is located

Create the ng build task

Clone the task and update the command as follows

Create the Azure App Service Deploy Task

This task will take your compiled .NET Core application and publish it to your Azure Web App service.

Connect it to your Azure subscription by following the instructions for the Azure subscription field and select your app

Set your package location to the output of the .NET Core: Publish task:


Stop the App Service Before the Build Process

In order to get around a bug where the app service isn’t completely stopped when it reaches the deploy task, we’re going to stop the Web App before the build process starts to ensure it’s completely shutdown.

Add the Azure App Service Manage task to the build process
Move the App Service Mange task to before the npm install task and change the Action to Stop App Service

Start the App Service after deployment

Clone the Stop App Service task
Move it to after the Deploy task and change its name and action to Start App Service

Enable Continuous Integration

Save the build definition

Change some code, commit it, and push it to your repository

Try adding a variable to your component
Show it in the title

git commit -m "To CI and beyond"

git push

The Sync operation performs a git pull and git push

Observe the build

Open the build definition you created
Select the queued build which was triggered by your push
You can view all console output as the build progresses
Navigate to your published web app

Happy building, friends.
