ASP.NET Core 9: Building a Time-Based Order Processing Application with ASP.NET Core 9 and TickerQ
In this article, we will build a complete Order Processing Application using ASP.NET Core 9 with TickerQ — a modern, source-generated background job scheduler for .NET. The application demonstrates how to accept orders through a web UI, store them in SQL Server, and automatically process them on a timed schedule using TickerQ's cron-based execution engine. What is TickerQ? TickerQ is a high-performance, modern job scheduler for .NET applications. Unlike traditional approaches such as IHostedService with Timer , or Hangfire, TickerQ leverages source generators at compile time — meaning zero runtime reflection, full AOT compatibility, and maximum performance. TickerQ supports two types of scheduled jobs: Time Tickers — One-off jobs scheduled to run at a specific future time. Cron Tickers — Recurring jobs defined using cron expressions (e.g., */1 * * * * for every minute). Key features of TickerQ include: Source-generated function registration : No ma...
