$net use` is not an option in this format. However, I can provide you with the summary of the text in a single paragraph. The tutorial describes how to build an appointment bot using Twilio SMS and Google Calendar API with C# and ASP.NET Core. It starts by setting up a Twilio account and connecting it to a Google Cloud project, where the OAuth flow is configured to request access to the Google Calendar. The app then builds a user configuration page to connect the Google account and set work hours and days. An SMS webhook is created to receive customer messages, extract appointment details, and create events in the Google Calendar if available. To prevent conflicts, it checks for existing events on the same date and time. Finally, the app is tested using ngrok to expose the local development environment over the internet, and a Twilio phone number is set up with the generated URL.
