Quickstart: Create a C# Durable Functions app

 Source: https://learn.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-isolated-create-first-csharp?pivots=code-editor-visualstudio

Use Durable Functions, a feature of Azure Functions, to write stateful functions in a serverless environment. Durable Functions manages state, checkpoints, and restarts in your application.

Like Azure Functions, Durable Functions supports two process models for .NET class library functions. To learn more about the two processes, see Differences between in-process and isolated worker process .NET Azure Functions.

In this quickstart, you use Visual Studio 2022 to locally create and test a "hello world" Durable Functions app. The function orchestrates and chains together calls to other functions. Then, you publish the function code in Azure. The tools you use are available via the Azure development workload in Visual Studio 2022.
