it had to be done

Real.cs

// do this

namespace Helpers
{
    public static class Helper
    {
        public static async Task PleaseStandUpAsync(this SemaphoreSlim s)
        {
            await s.WaitAsync();
        }

		public static void SitDown(this SemaphoreSlim s)
        {
            s.Release();
        }
    }
}

// so you can do this

var realSlimShady = new SemaphoreSlim(1);
await realSlimShady.PleaseStandUpAsync();
realSlimShady.SitDown();
