The problem is that you are trying to call the TestSemaphoreWithMultiParallelAccess() method from the main thread. Coyote tests must be run from a separate thread. The easiest way to do this is to use the Coyote.TestingServices.Test method. Here is a complete example:15using System;16using System.Collections.Generic;17using System.Linq;18using System.Text;19using System.Threading.Tasks;20using Microsoft.Coyote.BugFinding.Tests;21using Microsoft.Coyote.TestingServices;22{23    {24        static void Main(string[] args)25        {26            Test(async () =>27            {28                var test = new Microsoft.Coyote.BugFinding.Tests.SemaphoreSlimTests();29                test.TestSemaphoreWithMultiParallelAccess();30            });31        }32    }33}
