Concurrent Task Scheduler Library

Project roadmap

1. 01

   Design the ITask and schedule abstractions

   ~1.5h

   Define interfaces for schedulable tasks and their recurrence rules (once, interval, cron-like).

2. 02

   Implement the scheduling engine core

   ~2.5h

   Build a loop that determines which due tasks to run next using a priority queue keyed by next-run time.

3. 03

   Add concurrency-limited execution

   ~2.5h

   Use SemaphoreSlim or Channels to cap how many tasks run concurrently, queuing the rest.

4. 04

   Add cancellation and graceful shutdown

   ~2h

   Support CancellationTokens so running tasks and the scheduler itself can shut down cleanly.

5. 05

   Add error handling and retry policies

   ~2h

   Catch task exceptions, log them, and support configurable retry with backoff.

6. 06

   Build a demo console host

   ~1.5h

   Create a sample console app registering several demo tasks to showcase the library's behavior.
