In this article, we are going to see how to develop and deploy Azure web Job In Azure App service.
What is Azure WebJobs?
Azure WebJob is a feature of Azure App Service which runs a program or script in the background using a WebApp or WebAPI context. There is no additional cost to use WebJob. There are two types of web jobs.
- Continuous WebJob.
- Triggered WebJob.
- It starts immediately when Web Jobs is created.
- It runs in all instances of the Web App. You can optionally restrict the Web Jobs to a single instance
- It supports remote debugging.
- It starts manually or triggered.
- It runs on a single instance for load balancing.
- It does not support remote debugging.
Developing Azure WebJob using Visual Studio:
Here we will see, How to develop an Azure WebJobs using Visual Studio.
- Open Visual Studio 2019, Click Create a new project.
- Type Azure WebJob in the search box, choose Azure WebJob (.NET Framework) template and click Next.
- Give appropriate Project name and Solution name, choose the location and select the Framework. Then click create.
- This template creates a simple console application contains program.cs with Main Method and Function.cs file.
- The WebJobs SDK looks for Azure Storage connection string in the app.config file. So give the Azure Storage connection string like below.
- Let’s create a manual trigger using NoAutomaticTrigger attribute in Function.cs file
public void TriggerHandler(TextWriter log)
log.WriteLine(“Trigger is Fired”);
catch (Exception ex)
log.WriteLine(“Exception in Trigger Handler”, ex);
- In Program.cs file contains the main method, call the manual trigger using JobHost function like below
static void Main()
var config = new JobHostConfiguration();
var host = new JobHost(config)
Deploy Azure WebJob In Azure App service:
- Build the solution in Release mode.
- Go to bin/Release/net45 path of the application and add all the contents in a .zip file.
- Go to the Azure portal, select your App service then go to WebJobs and ADD a Job.
- Enter the Job name, select the .zip file. Choose the type triggered. We can choose the Triggers by scheduled or Manual.
- The scheduled WebJob will be executed based on the provided CRON expression.
- Enter the CRON Expression and click “Ok”.
- It will take a few minutes to add the Web Job.
- Then select the WebJob you uploaded and click Run button.
- You can see the status changed to Running, click Logs to see the WebJobs details like below.
