How to Get an SMS Delivery Receipt in ASP .NET MVC

The tutorial series aims to teach developers how to send and receive SMS using Vonage's API. To complete this task, a developer needs a Vonage API account and a virtual phone number. The process involves setting up an ASP.NET project and adding a controller called SMSController.cs. An action method called DLR is created in the SMSController.cs file to read the delivery receipt and print its status to the output window. The tutorial also covers using webhooks, ngrok, and Vonage CLI for testing and deployment purposes.
