  1. Challenge

    Add a Durable Orchestration Function to the Function App

    Create a new Durable Functions orchestrator function, and name it MyDurableFunctionsOrchestrator*. Skim the code, but don't change anything.

  2. Challenge

    Add a Durable Activity Function to the Function App

    Create a Durable Functions activity function, and name it Hello. Skim the code, but don't change anything.

  3. Challenge

    Create a Durable Functions HTTP Trigger Function in the Function App

    • Create a Durable Functions HTTP starter function, and name it MyDurableFunctionsHttpStart. Note that the starter function is often referred to as a "trigger" function in Microsoft documentation and, at some point, the UI may change to that term.
    • Copy the Function URL for use later in the lab.
    • Review the function code, and comment out (//) the dynamic eventData line.
    • Replace eventData on line 17 with null.
  4. Challenge

    Run the Durable Function Trigger and Get the Results with Azure CLI

    For this objective, you will need to use PowerShell. If you do not have experience with PowerShell and/or you are not comfortable researching the PowerShell code to complete this final step, switch over to the guide for this lab to copy-paste appropriate commands.

    • Start a Cloud Shell session using the existing storage account. You will need to start the session in the same region your lab resources are deployed.
    • Declare $startUrl using the URL you copied before, and replace {functionName} in the URL with MyDurableFunctionsOrchestrator.
    • Start the orchestration, converting the response content from JSON, and review the output of the orchestration.
