--- title: 'Build a scheduled WebJob using your preferred language' description: WebJobs on App Service enable you to automate repetitive tasks on your app. Learn how to create scheduled WebJobs in Azure App Service. ms.topic: tutorial ms.date: 10/29/2025 author: msangapu-msft ms.author: msangapu ms.reviewer: glenga zone_pivot_groups: app-service-webjobs #Customer intent: As a web developer, I want to leverage a scheduled background task to keep my application running smoothly. ms.service: azure-app-service --- # Tutorial: Build a scheduled WebJob :::zone target="docs" pivot="dotnet" WebJobs is a feature of Azure App Service that enables you to run a program or script in the same instance as a web app. All App Service plans support WebJobs at no extra cost. This tutorial walks you through creating a scheduled (triggered) WebJob using your preferred development stack. ## Prerequisites - An Azure account with an active subscription. [Create an account for free](https://azure.microsoft.com/pricing/purchase-options/azure-account?cid=msft_learn). - An existing App Service [.NET 9 app](quickstart-dotnetcore.md). - **[Always on](configure-common.md?tabs=portal#configure-general-settings)** must be enabled on your app. - For Windows containers and all Linux apps, ensure the app setting `WEBSITE_SKIP_RUNNING_KUDUAGENT` is set to `false`. ## Prepare the WebJob locally 1. In this step, you create a basic .NET WebJob project and navigate to the project root. ```bash dotnet new console -n webjob –framework net9.0 cd webjob ``` 1. Next, replace `Program.cs` to the following code that writes the current time to the console: ```dotnet using System; class Program { static void Main() { DateTimeOffset now = DateTimeOffset.Now; Console.WriteLine("Current time with is: " + now.ToString("hh:mm:ss tt zzz")); } } ``` 1. From the *webjob* directory, run the webjob to confirm the current time is output to the console: ```bash dotnet run ``` You should see output similar to the following: ```bash Current time with is: 07:53:07 PM -05:00 ``` 1. Once you confirm that the app works, build it and navigate to the parent directory: ### [Windows](#tab/windows) ```bash dotnet publish -c Release -r win-x64 --self-contained true /p:PublishSingleFile=true ``` ### [Linux](#tab/linux) ```bash dotnet publish -c Release -r linux-x64 --self-contained true /p:PublishSingleFile=true ``` --- 1. **(Linux only)** In the project root, create a `run.sh` with the following code to run the built executable: ```text #!/bin/bash ./webjob ``` 1. Now package the files into a .zip as shown in the following command: ### [Windows](#tab/windows) ```bash zip -j webjob.zip bin/Release/net9.0/win-x64/publish/webjob.exe ``` ### [Linux](#tab/linux) ```bash zip -j webjob.zip run.sh bin/Release/net9.0/linux-x64/publish/* ``` --- ## Create a scheduled WebJob in Azure 1. In the [Azure portal](https://portal.azure.com), go to the **App Service** page of your App Service app. 1.

[Download the sample Java WebJob](https://github.com/Azure-Samples/App-Service-Java-WebJobs-QuickStart). You will build a `.JAR` file using [Maven](https://github.com/microsoft/azure-maven-plugins/blob/develop/azure-webapp-maven-plugin/README.md). The Java project located at `project/src/main/java/webjob/HelloWorld.java` outputs a message & the current time to the console. ```Java import java.time.LocalDateTime; public class HelloWorld { public static void main(String[] args) { System.out.println("------------------------------------------------------------"); System.out.println("Hello World from WebJob: " + LocalDateTime.now()); System.out.println("------------------------------------------------------------"); } } ``` 1. Build and package the Java project to produce the executable `.jar` by running the following commands from the `project/` directory: ```bash mvn install mvn package ``` The jar files will be located at `project/target/webjob-artifact-1.0.0.jar` after a successful build. 1.
