Creating a scheduled job to clear photos from storage

The last thing we will do is clean the Blob storage at regular intervals and delete photos that are older than 1 hour. We will do that by creating a function that is triggered by TimeTrigger. Proceed as follows:

1. To create a new function, right-click the Chat.Functions project and click New Azure Function, which can be found under the Add menu.
2. Name the function ClearPhotos.
3. Select the option where the function will use a Timer trigger because we want it to run on a time interval.
4. Use a CRON expression to make it run every 60 minutes. Set the Schedule to 0 */60 * * * *, as illustrated in the following screenshot:

If you want to read more about CRON expressions, you can do so by going to the following URL: https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-timer?tabs=csharp#ncrontab-expressions
