He needs this done once every hour using the invocable classes he’s created. He then needs to do some CPU intensive processing to validate the data, and then store the results in his database. Santa has an API that he uses to fetch who is nice and naughty (it’s a secret end-point from his legacy system). Syncing data between an external API and your system.Processing messages from an external queue.They represent some “job” in your application: Invocables are ubiquitous classes that can be scheduled, queued, etc. With Coravel you can use Invocable classes to solve this problem. Santa needs something more maintainable and he really needs to inject his Entity Framework Core Db context, HttpClientFactory, etc. NET Core Dependency Injection With Invocables

This will be a console app that hooks into Coravel’s scheduler.Įvery minute something will happen. WriteLine ( "This was scheduled every minute." ) ). Build ( ) // Configure the scheduled tasks. Using the sample mentioned above, let’s look at a very basic implementation of using HostBuilder along with Coravel’s scheduling: class Program ). This means Coravel is 100% compatible in non-web scenarios. NET Core, Coravel’s features - such as scheduling and queuing - are implemented as a hosted services. NET Framework library, but is specially built for.
#Asp net scheduled task full#
Then you can “host” whatever you need (mini-API endpoints, console app running background tasks, or multiple hosted services) without the full dependencies needed for a typical web project.īecause Coravel is not a port of a. NET Core application by adding just the specific pieces you need. The HostBuilder, by the way, let’s you construct a. NET Core’s coolest features, HostBuilder, and you can do some really powerful things in just a few lines of code. NET Core is that it’s so simple to configure.Ĭombined with one of. One of the benefits of Coravel being specially for. He agreed, but I was only permitted to show a very small sample of his system. I asked Santa if I could share how he decided to implement this.

It turns out that there is a sample to address this exact concern! Santa decided to check out Coravel’s GitHub repo - just in case this has been addressed before. NET Core application is not an option since doing these types of long-running tasks in a web app will cause issues (as you probably know). And these are important tasks.ĭoing this inside his ASP. Drawbackīut - now Santa has to schedule some really long running tasks. He especially loves that Coravel ties into.
#Asp net scheduled task install#
Santa has really enjoyed using Coravel - especially the time savings gained from not having to configure and install other dependencies for scheduling, queuing, event broadcasting, etc. NET Core, it takes advantage of native features - such as full support for the built-in dependency injection services and the hosted background services.įor example, you can inject dependencies/services into scheduled tasks, queued tasks, event listeners, etc. It makes what are usually very advanced features super easy-to-use and accessible - without needing to install any extra 3rd-party infrastructure:īecause it’s written specifically as a set of tools targeted for.
#Asp net scheduled task code#
NET Core developers.Ĭoravel focuses on helping developers get their web applications up-and-running fast - without compromising code quality. One day he came across Coravel - which is a near-zero config open source library for. Santa didn’t want to re-invent the wheel - but he needed a reliable yet simple way to schedule background tasks, queue work so his web app was responsive (mostly for the elves), etc. NET Core was the best choice when considering these criteria.

He recently needed to build a system that was robust in terms of security and ease of development. Santa is an intermediate developer but has been learning the ins-and-outs of. NET Core to build his internal Christmas present processing system. In the spirit of the season, we’ll be discussing how Santa Clause has recently been using.
