PM>Install-Package Nunit.ConsoleRunner -Version 3.8.0

Sample example program here:

using NUnit.Framework;
using Prime.Services;

namespace Prime.UnitTests.Services
{
[TestFixture]
public class PrimeService_IsPrimeShould
{
private readonly PrimeService _primeService;

public PrimeService_IsPrimeShould()
{
_primeService = new PrimeService();
}

[Test]
public void ReturnFalseGivenValueOf1()
{
var result = _primeService.IsPrime(1);

Assert.IsFalse(result, "1 should not be prime");
}
}
