Azure Integration with .NET

Explore how to leverage the power of Microsoft Azure services within your .NET applications.

This guide provides comprehensive documentation, code examples, and best practices for integrating your .NET applications with various Azure services. From managed databases and messaging queues to AI/ML services and serverless compute, Azure offers a robust platform for building scalable and resilient applications.

Key Azure Services for .NET Developers

• Azure App Service: Host your ASP.NET, ASP.NET Core, and other web applications on a fully managed platform.
• Azure Functions: Build event-driven, serverless applications with C# and .NET.
• Azure SQL Database: A fully managed relational data service that makes relational data simple.
• Azure Cosmos DB: A globally distributed, multi-model database service for modern app development.
• Azure Service Bus: Reliable cloud messaging as a service for connecting applications and services.
• Azure Storage: Scalable and secure object, file, and queue storage.
• Azure Cognitive Services: Integrate intelligent capabilities like vision, speech, and language into your .NET apps.
• Azure Kubernetes Service (AKS): Orchestrate containerized .NET applications at scale.

Getting Started

Code Examples

Connecting to Azure SQL Database

Example demonstrating how to connect to and query an Azure SQL Database using Entity Framework Core in a .NET application.

using Microsoft.EntityFrameworkCore;
using System.Threading.Tasks;

public class MyDbContext : DbContext
{
    public DbSet<Product> Products { get; set; }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        var connectionString = "Server=tcp:your_server.database.windows.net,1433;Initial Catalog=your_database;Persist Security Info=False;User ID=your_user;Password=your_password;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;";
        optionsBuilder.UseSqlServer(connectionString);
    }

    public async Task<int> GetProductCountAsync()
    {
        return await Products.CountAsync();
    }
}

public class Product {
    public int Id { get; set; }
    public string Name { get; set; }
}

Sending a Message to Azure Service Bus

Illustrates sending a message to an Azure Service Bus queue using the Azure SDK for .NET.

using Azure.Messaging.ServiceBus;
using System.Threading.Tasks;

public class ServiceBusSender
{
    private const string connectionString = "YOUR_SERVICE_BUS_CONNECTION_STRING";
    private const string queueName = "YOUR_QUEUE_NAME";

    public async Task SendMessageAsync(string messageBody)
    {
        await using var client = new ServiceBusClient(connectionString);
        ServiceBusSender sender = client.CreateSender(queueName);

        try
        {
            var message = new ServiceBusMessage(messageBody);
            await sender.SendMessageAsync(message);
            Console.WriteLine($"Sent message: {messageBody}");
        }
        finally
        {
            await sender.DisposeAsync();
            await client.DisposeAsync();
        }
    }
}

Best Practices

• Security: Utilize Azure Key Vault for managing secrets and credentials. Implement proper authentication and authorization mechanisms.
• Scalability: Design your applications to take advantage of Azure's auto-scaling capabilities.
• Monitoring: Integrate Azure Monitor for performance tracking and error detection.
• Cost Management: Optimize resource usage and leverage cost-saving features offered by Azure.
