🌐 Building a Lead Generation Website with Modern .NET and Azure SQL

Introduction

Lead generation websites are the backbone of digital marketing. But too often, they’re built with outdated stacks that don’t scale or integrate well with modern workflows. Let’s explore how to build a scalable, cloud-ready lead generation site using .NET 8, Azure SQL, and GitHub Actions.

The Challenge

• Traditional CMS platforms are heavy and slow.
• Manual deployments lead to downtime and errors.
• Data pipelines for leads are often insecure or fragmented.

The Modern Approach

By combining .NET 8 minimal APIs, Azure SQL, and CI/CD pipelines, we can create a lean, secure, and automated system.

Step 1: Define the Lead Model

public class Lead
{
    public int Id { get; set; }
    public string Name { get; set; } = default!;
    public string Email { get; set; } = default!;
    public DateTime CreatedAt { get; set; } = DateTime.UtcNow;
}

Step 2: Minimal API Endpoint

var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();

app.MapPost("/leads", async (Lead lead, SqlConnection conn) =>
{
    var cmd = new SqlCommand("INSERT INTO Leads (Name, Email, CreatedAt) VALUES (@n, @e, @c)", conn);
    cmd.Parameters.AddWithValue("@n", lead.Name);
    cmd.Parameters.AddWithValue("@e", lead.Email);
    cmd.Parameters.AddWithValue("@c", lead.CreatedAt);
    await cmd.ExecuteNonQueryAsync();
    return Results.Created($"/leads/{lead.Id}", lead);
});

app.Run();

Step 3: Automate with GitHub Actions

• Build and test with every commit.
• Deploy to Azure Web App automatically.
• Run integration tests with Testcontainers for reliability.

Why This Matters

• 🚀 Speed: Minimal APIs keep things lightweight.
• 🔒 Security: Azure SQL with managed identities.
• ⚡ Automation: CI/CD ensures zero manual deployment errors.

Closing Thought

Lead generation doesn’t have to mean clunky WordPress sites. With modern .NET and Azure, you can build a system that’s fast, secure, and future-proof.
