What are durable functions?

• Durable Functions allow stateful workflows in serverless apps.
• Enable orchestration, chaining, and long-running tasks without managing state

manually.

Example:

[FunctionName("OrchestratorFunction")]

public static async Task RunOrchestrator(

[OrchestrationTrigger] IDurableOrchestrationContext context)

await context.CallActivityAsync("HelloActivity", "Tokyo");

await context.CallActivityAsync("HelloActivity", "Seattle");
