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 additional cost. This sample uses a scheduled (Triggered) WebJob to output the system time once every minute.

## Create your sample WebJob
27+
28+
1. In this step, you create a basic .NET WebJob project and navigate to the project root.
29+
30+
```bash
31+
dotnet new console -n webjob –framework net9.0
32+
33+
cd webjob
34+
```
35+
36+
1. Next, replace `Program.cs` to the following code to write the current time to the console:
37+
38+
```dotnet
39+
using System;
40+
41+
class Program
42+
{
43+
static void Main()
44+
{
45+
DateTimeOffset now = DateTimeOffset.Now;
46+
Console.WriteLine("Current time with is: " + now.ToString("hh:mm:ss tt zzz"));
47+
}
48+
}
49+
```
50+
51+
1. From the webjob directory, run the webjob to confirm the current time is output to the console:
52+
53+
```bash
54+
dotnet run
55+
```
56+
57+
You should see output similar to the following:
58+
59+
```bash
60+
Current time with is: 07:53:07 PM -05:00
61+
```
62+
63+
1. Once you've confirmed the app works, build it with the following command:
64+
65+
```bash
66+
dotnet build --self-contained
67+
```
68+
69+
70+
1. Next we to create `run.sh` with the following code:
71+
72+
```text
73+
#!/bin/bash
74+
75+
Dotnet webjob/bin/net9.0/webjob.dll
76+
```
77+
78+
1. Now we navigate to the parent folder and package all the files into a .zip as shown below:
79+
80+
```bash
81+
cd ..
82+
zip webjob.zip run.sh webjob/bin/Debug/net9.0/*
83+
```
84+
85+
## Create a scheduled WebJob in Azure
86+
87+
1. In the [Azure portal](https://portal.azure.com), go to the **App Service** page of your App Service app.
88+
89+
1. From the left pane, select **WebJobs**, then select **Add**.
90+

92+
93+
1. Fill in the **Add WebJob** settings as specified in the table, then select **Create Webjob**. For **File Upload**, be sure to select the .zip file you downloaded earlier in the [Download the sample WebJob](#download-the-sample-webjob) section.

| Setting | value | Description  |
98+
| ------------ | ----------------- | ------------ |
99+
| **Name** | webjob | The WebJob name. Must start with a letter or a number and must not contain special characters other than "-" and "_". |
100+
| **File Upload** | webjob.zip | The *.zip* file that contains your executable or script file. The supported file types are listed in the [supported file types](webjobs-create.md?tabs=windowscode#acceptablefiles) section. |
101+
| **Type** | Triggered | Specifies when the WebJob runs: Continuous or Triggered. |
102+
| **Triggers** | Scheduled | Scheduled or Manual. Ensure [Always on](configure-common.md?tabs=portal#configure-general-settings) is enabled for the schedule to work reliably.|
103+
| **CRON Expression** | 0 0/1 * * * * | For this quickstart, we use a schedule that runs every minute. See [CRON expressions](webjobs-create.md?tabs=windowscode#ncrontab-expressions) to learn more about the syntax. |
104+
105+
1. The new WebJob appears on the **WebJobs** page. If you see a message that says the WebJob was added, but you don't see it, select **Refresh**.
106+
107+
1. The scheduled WebJob is run at the schedule defined by the CRON expression.
