title: How to apply automation on “Windows authentication dialog” and login into the web application using c# , selenium webdriver
body: <p>I am trying to login in the web application through the Windows authentication popup. I tried to switch the window using “driver.SwitchTo().Alert()”.
  And I also tried to use “driver.get(“http//user:pass@siteurl.com”)” but nothing is working. Always getting the same exception “Model dialog Present”.
  How can I find the text box and enter the credential.
  I am using .net(c#) with selenium webdriver and working in Visual studio.</p>
