How to send sms using C# and twilio API

Question

I'm trying to create a User interface where the user can enter her credential and phone number and send messages to some recipient using Twilio API

So as explained I created my account and initialized the Authentication key and token

    private void button1_Click(object sender, EventArgs e)
    {
         string ssid = twilioSSIDBox.Text;
         string token = twilioTokenBox.Text;
         string number = twilioNumberBox.Text;


        var client = new TwilioRestClient(Environment.GetEnvironmentVariable(ssid), Environment.GetEnvironmentVariable(token));
        client.SendMessage(number, "+158965220", "Teting API message!");

    }

After multiple test (hard coding the ssid and token and number ) and documentation consulting , the message is still not being sent on the visual studio platform and I'm not receiving any error message or anything

So my question is what I am missing? Do I need a certain library that allow visual studio to be able to send sms messages?

I'm using Visual studio 2015 and windows 10 platform

Thank you

I end up resolving my problems

so this was not working on VS2015 Platform :

    var client = new TwilioRestClient(Environment.GetEnvironmentVariable(ssid), Environment.GetEnvironmentVariable(token));
    client.SendMessage(number, "+158965220", "Teting API message!");

Even thought I already installed the Twilio api version 4.7.2 using nuget console

I did again the following :

Install-Package Twilio

than Visual studio suggest me to add reference to the API inside the code

 using Twilio;
using Twilio.Rest.Api.V2010.Account;
using Twilio.Types;

Thanks to the following Example

this has worked :

 TwilioClient.Init(accountSid, authToken);

        var message = MessageResource.Create(
            to: new PhoneNumber(toNumber),
            from: new PhoneNumber(FromNumber),
            body: "Hello from C#");

So my conclusion is probably an outdated library because when I used NUGET to install:

Install-Package Twilio -Version 4.7.2

I have no idea why it wasn't working

P.S: I'm not sure if it was relevant but I also installed this using NUGET console it mighed helped or it might not but I felt like I had to mention it :

Install-Package RestSharp
