Trouble running first QDK Bell test

[stanescuUW]

After having done the steps on the "Writing first program page" my codes (macOS) look like this:

Bell.qs

namespace Quantum.Bell
{
    open Microsoft.Quantum.Canon;
    open Microsoft.Quantum.Intrinsic;

    operation Set (desired: Result, q1: Qubit) : Unit {
        if (desired != M(q1)) {
            X(q1);
        }
    }
    operation BellTest (count : Int, initial: Result) : (Int, Int) {

        mutable numOnes = 0;
        using (qubit = Qubit()) {

            for (test in 1..count) {
                Set (initial, qubit);
                let res = M (qubit);

                // Count the number of ones we saw:
                if (res == One) {
                    set numOnes += 1;
                }
            }
            Set(Zero, qubit);
        }

        // Return number of times we saw a |0> and number of times we saw a |1>
        return (count-numOnes, numOnes);
    }
}

and the Driver.cs looks like this:

using System;

using Microsoft.Quantum.Simulation.Core;
using Microsoft.Quantum.Simulation.Simulators;

namespace BellTest
{
    class Driver
    {
        static void Main(string[] args)
        {
            using (var qsim = new QuantumSimulator())
            {
                // Try initial values
                Result[] initials = new Result[] { Result.Zero, Result.One };
                foreach (Result initial in initials)
                {
                    var res = BellTest.Run(qsim, 1000, initial).Result;
                    var (numZeros, numOnes) = res;
                    System.Console.WriteLine(
                        $"Init:{initial,-4} 0s={numZeros,-4} 1s={numOnes,-4}");
                }
            }

            System.Console.WriteLine("Press any key to continue...");
            Console.ReadKey();
        }
    }
}

However, I get the following error messages upon running:

 Restore completed in 26.27 ms for /Users/danstanescu/Dropbox/JupyterNotebooks/MicrosoftQDK/Bell/Bell.csproj.
/Users/danstanescu/Dropbox/JupyterNotebooks/MicrosoftQDK/Bell/Driver.cs(18,31): error CS0234: The type or namespace name 'Run' does not exist in the namespace 'BellTest' (are you missing an assembly reference?) [/Users/danstanescu/Dropbox/JupyterNotebooks/MicrosoftQDK/Bell/Bell.csproj]

The terminal process terminated with exit code: 1

Any help will be greatly appreciated.
