# Azure Durable Functions (Function Chaining Example) in C# .NET (Starter Template)
##### Starter Template for Azure Serverless Durable Functions .NET Core
*Author: Jonah Andersson*
#### DESCRIPTION:
This is a starter template for Serverless deveöpment with Azure Durable Functions available to those you wants to try it out.
A hands-on lab created with Azure Durable Functions with [Function Chaining](https://docs.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-sequence?tabs=csharp) application pattern.
This template is prepared as starter template that allows you to develop Azure Functions (Durable Functions) serverless workflow with integration to other APIs such as Twilio API and Sendgrid API and Azure services - Azure Storage, ServiceBus etc.
#### OVERVIEW OF WORKFLOW
Azure Durable Functions - Function Chaining Example with Azure Service Bus, Twilio API, Sendgrid API and Azure BLOB Storage
### EXPECTED RESULTS
- Orchestration get trigged by an image or BLOB uploaded to the Azure Storage
- Chain 1 - Sends queue message to Azure Service Bus
- Chain 2 - Send SMS or make call using Twilio API
- Chain 3 - Send email to configured email address using SendGrid API
- Chain 4 - Lab Exercise to send to Azure Cosmos DB etc. (Guide: How to create Azure Cosmos DB Trigger)
#### PREREQUISITES AND LAB ENVIRONMENT SETUP
* Basics concepts of Azure Serverless Computing, Azure Functions and Durable Functions
(*If you are a student of Forefront's Serverless course, great. Otherwise, check *Recommended Learning* below*)
* Microsoft Azure account - Private or Organization subscription account
(*If you don't have any Azure Account, sign up https://azure.microsoft.com/en-us/free/*)
* Latest version of [Visual Studio](https://visualstudio.microsoft.com/) or [VS Code](https://code.visualstudio.com/)
* Azure Storage Explorer (https://azure.microsoft.com/en-us/features/storage-explorer/)
* Programming Language C# .NET (You can code in other supported languages as well - see supported languages)
* Install latest .NET Core 3.1 (LTS) or latest supported like .NET 6 https://dotnet.microsoft.com/download
* Install [Azure Functions Core Tools](https://docs.microsoft.com/en-us/azure/azure-functions/functions-run-local?tabs=v3%2Cwindows%2Ccsharp%2Cportal%2Cbash%2Ckeda)
* If you are using .NET Core 3.1 it will not be supported by the end of 2022 and you need to upgrade to functions version 4.0
* Postman for HTTP Requests/Triggers
* DEVELOPMENT LOCALLY use file local.settings.json with your own configuration strings, API keys
#### local.settings.json (Local Development Only)
*RECOMMENDATION:* Use [Azure Key Vault](https://docs.microsoft.com/en-us/azure/app-service/app-service-key-vault-references?tabs=azure-cli?WT.mc_id=AZ-MVP-5004251) and Managed Identities to secure your function application for Azure Durable Functions

### WHEN DEBUGGING AND DEVELOPING LOCALLY
When developing Azure Functions locally using this project. You should see similar like this when it is finished.
It logs what is happening with your orchestration. You may also check on
