Selenium WebDriverWait throwing exception

Question

I'm trying to wait until a element is present before continuing, however with the method I'm currently using it's throwing element does not exist, even before timeout has ended.

Example usage:

 using OpenQA.Selenium;
 using OpenQA.Selenium.Chrome;
 using OpenQA.Selenium.Support.UI;

 private static WebDriverWait wait = new WebDriverWait(driver, System.TimeSpan.FromSeconds(30)); // inside parent class (not method)

 //public static void Method1()

 wait.Until(driver => driver.FindElement(By.CssSelector("[foo=bar]")));

which should then wait 30 seconds or until element is present, but it instantly throws element not found exception...

Try using ExpectedConditions class in general and ElementExists() function in particular, suggested code:

Example code:

WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
IWebElement element  = wait.Until(ExpectedConditions.ElementExists(By.CssSelector("[foo=bar]")));

Example output:
