Discovering the Durable Functions API - Starting orchestrations (DurableOrchestrationClient part 1)

DurableOrchestrationClient(Base) class - Starting & waiting for completion

This post is the first part of a series of blogs/vlogs to discover the Durable Functions API.

In the video linked below, I’m looking into methods from the DurableOrchestrationClient(Base) class on how to start a new orchestration instance and how to retrieve the status and the result of the instance:

• StartNewAsync(string orchestratorFunctionName, object input)
• StartNewAsync(string orchestratorFunctionName, string instanceId, object input)
• CreateCheckStatusResponse(HttpRequestMessage request, string instanceId)
• WaitForCompletionOrCreateCheckStatusResponseAsync(HttpRequestMessage request, string instanceId)
• WaitForCompletionOrCreateCheckStatusResponseAsync(HttpRequestMessage request, string instanceId, TimeSpan timeout)
• WaitForCompletionOrCreateCheckStatusResponseAsync(HttpRequestMessage request, string instanceId, TimeSpan timeout, TimeSpan retryInterval)

Here’s the video, please give it a thumbs up if you like it and subscribe to my channel so you’ll be notified of new videos:
