Azure Functions Demo Project - ASP.NET Core (C#)

This repository is a collection of Azure Functions demonstrating various trigger types using C# and ASP.NET Core. Each function showcases how to integrate with different Azure services, providing a practical starting point for building serverless applications on Azure.

🚀 Trigger Types Included

Trigger Type	Description
HTTP Trigger	Responds to HTTP requests. Ideal for APIs and webhooks.
Timer Trigger	Executes on a scheduled interval (cron). Useful for background jobs.
Blob Trigger	Runs when a new blob is added or updated in Azure Blob Storage.
Queue Trigger	Processes messages from Azure Storage Queues.
Service Bus Trigger	Listens to Azure Service Bus queues or topics. Great for messaging between services.
Event Grid Trigger	Handles events from Azure services like Blob Storage or custom topics.
Event Hub Trigger	Consumes data from Azure Event Hubs. Ideal for telemetry and event streaming.
Cosmos DB Trigger	Reacts to inserts and updates in a Cosmos DB collection.

📦 Prerequisites

• .NET 6 SDK or later
• Azure Functions Core Tools
• Visual Studio 2022+ or VS Code with Azure Functions extension
• Azure Subscription (for deploying and testing in the cloud)

▶️ Running Locally

1. Clone the repository:

   git clone https://github.com/your-username/azure-functions-demo.git
   cd azure-functions-demo

Start the functions:

bash Copy Edit func start Use tools like Postman, curl, or Azure Storage Explorer to test each trigger.

☁️ Deployment To deploy to Azure:

bash Copy Edit func azure functionapp publish Make sure the required resources (e.g., blob containers, queues, Event Hubs) are created and connected via local.settings.json or Azure portal configuration.

📄 Configuration Use local.settings.json to configure connection strings and settings during local development.

json Copy Edit { "IsEncrypted": false, "Values": { "AzureWebJobsStorage": "UseDevelopmentStorage=true", "FUNCTIONS_WORKER_RUNTIME": "dotnet", "BlobStorageConnection": "<your_connection_string>", "QueueStorageConnection": "<your_connection_string>", "ServiceBusConnection": "<your_connection_string>", "EventHubConnection": "<your_connection_string>", "CosmosDBConnection": "<your_connection_string>" } } ⚠️ Don't commit local.settings.json to source control.
