The type or namespace name 'Twilio' could not be found

Question

So I've got a dotnet core app, I'd like to use Twilio so I performed the following from the command line.

dotnet add package Twilio

All went well, no errors. It adds version 5.1.1 of Twilio packages. But building the app now gives me

The type or namespace name 'Twilio' could not be found

I'm running .Net core version 1.1 with the equivalent 1.0.1 SDK.

Any ideas?

Did you restore? The following works for me.

dotnet new console
dotnet add package Twilio
dotnet restore              <---- We need to restore after adding a package.
dotnet build

Program.cs

using Twilio;

class Program
{
    static void Main(string[] args)
    {
        TwilioClient.SetUsername("foo");
    }
}
