Fire-and-forget background jobs using Azure Durable Functions

Question

I have a use case which requires me to fire some Azure Durable Functions without caring about its results, and I was wondering if my approach is the correct one.

This is the scenario I'm in:

• Function A uses an HttpTrigger
• Function B uses an ActivityTrigger

This is my workflow:

• A is invoked and needs to do some business logic
• Alongside this business logic, I need to do a long background task that may or may not fail. I don't care about the results, but I need to run this task everytime A is invoked.
• A needs to return as quick as possible, that's why I can't wait for the background task to finish
• B takes care of this background task while A returns

All the Durable Functions examples that I'm finding online show something like this:

await starter.StartNewAsync("BackgroundDurableFunction", data)

My issue is here is that I don't want to await the Durable Function but I need it to just run in background and do its things (mostly network I/O).

To avoid waiting for this Durable Function I ended up with this workaround:

Task.Factory.StartNew(() => starter.StartNewAsync("BackgroundDurableFunction", data));

This seems to work just right, as I don't need to await anything, but after reading The Dangers of Task.Factory.StartNew I'm a little bit scared that this might be a dangerous solution.

So, the question is: what's the correct way to start a Durable Function and have it run in background without caring about its results (and without having warnings about not waiting for the task)?
