Using Durable Azure Functions in .NET 7 | .NET Conf 2022

With .NET 7 durable functions will be available for Azure Functions running in isolated mode. I've found that many people I've chatted to aren't aware of durable functions. They can drastically simplify implementations by coordinating various distributed functions and queues.

I'd love to be able to show some realistic use cases for using these, specifically using isolated functions (which will be available from .NET 7).

Hi, for those that asked, the source code can be found on github - NielsFilter - DurableFunctions (sorry about the contrived link). My comment keeps getting removed if I put the actual link in the comments 🤦‍♂

Thank you for a great presentation on durable functions!

Best video about Durable Functions so far. Great. Thanks.

One of the best explanations I have seen for in-proc vs isolated. Great explanation of the different use cases for durable. It finally all makes sense! 🙂 Can you please share the source code?

I spent tons of time to understand durable functions, but this video just did the work for me in half an hour. Thanks a lot. One question, can we write the activity functions in other languages like JS or python while everything else (starter & orchestrator) is in C#?

Thanks Niels, excellent video!
I'm wondering what happens if you change and redeploy your function before the 48 hour timeout and Paul still hasn't sent the response?
What logic changes could a durable function support, or does each execution start and end with the same version of the function?

Very useful thanks! do you have a video doing it from scratch?

Great video on durable functions. However, when creating a durable function, it doesn't provide an option to choose a trigger. By default it is HTTP. You mentioned that the durable functions can be timer triggered. Is there any documentation or examples.

Can you show how to return a List of DTO from activity function. I managed to return a DTO from activity function, turns out it's not easy as you have to put the DTO inside a specific namespace. But List<DTO> is not working. Can you show a demo for that

Very detailed explanation. Could you please share this code
