Workflows

This guide covers techniques for coordinating and managing complex task execution workflows. Learn how to chain tasks, build multi-step processes, and orchestrate sophisticated business workflows.

Overview

EverTask provides powerful capabilities for building complex, multi-step workflows:

• Task Orchestration: Chain tasks, handle cancellation, and reschedule dynamically
• Custom Workflows: Build sophisticated business processes with state machines and sagas

When to Use Task Orchestration

Most applications start with simple, independent tasks. Consider orchestration when you need to:

Task Chaining

• Execute multiple tasks in sequence
• Pass data between related tasks
• Branch workflows based on task results
• Implement conditional task execution

Complex Workflows

• Multi-stage business processes (order processing, payment flows)
• Saga patterns with compensation and rollback
• State machine-based workflows
• Parallel task execution with coordination

Best Practices

Continuations

1. Keep Chains Short: Long chains are debugging nightmares
2. Store Correlation IDs: Use GUIDs to trace through multiple tasks
3. Handle Failures Gracefully: Always implement OnError to clean up after failures
4. Consider Idempotency: Tasks might get retried or run multiple times

Cancellation

1. Check CancellationToken: Respect the cancellation token in your handlers
2. Clean Up Resources: Dispose resources properly when cancelled
3. Log Cancellations: Track when and why tasks get cancelled
4. Test Cancellation: Make sure your handlers actually handle cancellation correctly

Next Steps
