Twilio empowers developers to add communication technology to their applications by providing APIs and SDKs for sending SMS and MMS, WhatsApp messages, and emails, or making phone calls and video calls. To send an SMS from an F# console application, a free Twilio account is required, along with the .NET 7 SDK and a code editor or IDE. The user secrets configuration package is used to store sensitive authentication information, such as the Account SID and Auth Token. A helper library for .NET is used to simplify sending SMS messages, allowing developers to easily integrate communication technology into their applications.
