Using Azure WebJobs in .NET Applications

It is a very common requirement for web applications to be able to run background tasks. Scheduling tasks to run at specific times or intervals, triggering jobs to run based on certain events, etc are common scenarios that we encounter while developing applications. In this article, we are going to learn about Azure WebJobs which provides an excellent way of accomplishing this in a cloud environment. We’ll start by learning what an Azure WebJob is. Then we’ll look at different types of WebJobs. After that, we’ll learn how to use the Azure WebJobs SDK to create a triggered background job that runs when a new message arrives in the Azure Storage Queue. We’ll test it locally by creating a queue and adding a message. Finally, we’ll deploy it to Azure and test it.
