Build Dapr workflows in .NET with Aspire
Duration: 30 minutes
Supported languages: .NET
Learn how to build a code-first, fault-tolerant Dapr Workflow application that runs with Aspire. In this hands-on track you'll scaffold a new Aspire solution, wire up Dapr Workflow, and use the Diagrid Dev Dashboard to inspect the workflow state as it runs locally.
What you'll build
The Enterprise Diagnostics application — this application performs diagnostics on the star ship USS Enterprise. It uses Dapr Workflow to fan out to three star ship subsystem activities in parallel, aggregates the results into a prioritized report, and conditionally notifies the bridge.
In this self-paced course, you'll learn:
- How Dapr and .NET Aspire complement each other when building distributed applications.
- How to scaffold a new Aspire solution and add the NuGet packages required for Dapr Workflow.
- How to define a Dapr Workflow that uses the fan-out / fan-in pattern, with multiple parallel activities and conditional follow-up.
- How to configure Dapr state store components so workflow state is persisted across runs.
- How to register Dapr Workflow as an Aspire resource alongside the API service and its Dapr sidecar.
- How to trigger workflows via HTTP and inspect their state, execution history, and activity inputs/outputs in the Diagrid Dev Dashboard.
