Twilio provides a simple HTTP-based API for sending and receiving phone calls and text messages. Learn more at http://www.twilio.com
The best and easiest way to add the Twilio libraries to your .NET project is to use the NuGet package manager.
From within Visual Studio, you can use the NuGet GUI to search for and install the Twilio NuGet package. Or, as a shortcut, simply type the following command into the Package Manager Console:
Install-Package Twilio
If you are building with the .NET Core command line tools, then you can run the following command from within your project directory:
dotnet add package Twilio
The examples below show how to have your application initiate and outbound phone call and send an SMS message using the Twilio .NET helper library:
TwilioClient.Init("ACCOUNT_SID", "AUTH_TOKEN");
var call = CallResource.Create(
new PhoneNumber("+11234567890"),
from: new PhoneNumber("+10987654321"),
url: new Uri("https://my.twiml.here")
);
Console.WriteLine(call.Sid);
var message = MessageResource.Create(
new PhoneNumber("+11234567890"),
from: new PhoneNumber("+10987654321"),
body: "Hello World!"
);
Console.WriteLine(message.Sid);
var gather = new Gather(numDigits: 1, action: "hello-monkey-handle-key.cshtml", method: "POST")
.Say("To speak to a real monkey, press 1. Press 2 to record your own monkey howl. Press any other key to start over.");
var response = new VoiceResponse()
.Say("Hello Monkey")
.Play("http://demo.twilio.com/hellomonkey/monkey.mp3")
.Gather(gather);
Console.WriteLine(response);
/*
<?xml version="1.0" encoding="utf-8"?>
<Response>
<Say>Hello Monkey</Say>
<Play>http://demo.twilio.com/hellomonkey/monkey.mp3</Play>
<Gather numDigits="1" action="hello-monkey-handle-key.cshtml" method="POST">
<Say>To speak to a real monkey, press 1. Press 2 to record your own monkey howl. Press any other key to start over.</Say>
</Gather>
</Response>

See the migration guide here. Also, if you were using the Twilio.Mvc package, that has been replaced by the Twilio.AspNet.Mvc package which is compatible with this version of the library.
The alpha version of the Twilio .NET library is available on nuget. This version is a superset of the mainline version that includes all of the Twilio Products that are currently in beta. To install the alpha version from the NuGet Package manager console, add the -prerelease flag to the Install-Package command:
Install-Package Twilio -prerelease
If you need help installing or using the library, please contact Twilio Support at [email protected] first. Twilio's Support staff are well-versed in all of the Twilio Helper Libraries, and usually reply within 24 hours.
