Hangfire is an open-source library designed to create and manage background jobs in .NET applications. It facilitates the execution of tasks outside the request processing pipeline, improving scalability and efficiency by offloading work to be processed asynchronously. Hangfire supports a variety of job types, including fire-and-forget, delayed, recurring, and continuations, all of which can be easily managed through a web-based dashboard. It is compatible with several storage options, such as SQL Server, Redis, and more, providing flexibility for various application needs. By integrating with your .NET applications, Hangfire simplifies and streamlines background processing tasks.
