Azure Functions and Durable Task Scheduler with Aspire

This sample demonstrates the orchestration of the local startup of an Azure Functions project backed by the Durable Task Scheduler (DTS) using Aspire.

Prerequisites

• Docker (for starting Azure Storage and DTS emulators)
• .NET SDK 10 or later

Starting the application

Open a terminal at the AzureFunctionsAndDtsWithAspire host folder and run:

cd AspireHost
dotnet run

The Aspire host should start the application and present a URL to its dashboard:

Starting an orchestration

From the Aspire dashboard, open the logs for the Azure Functions (funcapp) resource and start an orchestration using the SampleOrchestration_HttpStart link.

Observing the orchestration

From the Aspire dashboard, open the details panel for the DTS (dts) resource and browse to its dashboard endpoint and its default taskhub. Select the new orchestration to see its event timeline.
