How to dispose after each test in parallel testing xunit?

Question

My tests in Selenium Xunit 2.0 from different collection class run parallel and dispose method call once only. I want to call to dispose the method after each test run even if they run in parallel.

[TestClass]
    public class Basic : IDisposable
    {
       
        protected void StopDriver()
        {
            #capture screenshot here
        }

        public void Dispose()
        {
            StopWebDriver();
            WebDriver.Dispose();
        }
    }
