This tutorial demonstrates how to implement instant lead alerts for a real estate application using C# and ASP.NET MVC with Twilio Programmable SMS. The system allows users to request more information about a house on the market, and upon submission of their form data, sends a text message to a designated real estate agent's phone number with the user's name, phone number, and inquiry details. The agent can then immediately follow up with the lead. The application utilizes Twilio's REST API client to send messages and integrates with ASP.NET MVC for routing and handling HTTP requests.
