Close all tabs except first one and switch to first tab:

var tabs = driver.WindowHandles; // 

foreach (var tab in tabs)
{
     // "tab" is a string like "CDwindow-6E793DA3E15E2AB5D6AE36A05344C68"
     if (tabs[0] != tab) 
     {                                    
         driver.SwitchTo().Window(tab); 
         driver.Close();
     }
}

driver.SwitchTab(tabs[0]); // Switch to first tab
driver.SwitchTo().DefaultContent(); // Switch to default frame

Pay attention to last two lines, they are need to avoid such errors like OpenQA.Selenium.NoSuchWindowException: no such window: target window already closed from unknown error: web view not found
