C# Selenium 'ExpectedConditions is obsolete'

Question

When trying to explicitly wait for an element to become visible using ExpectedConditions, Visual Studio warns me that it is now obsolete and will be removed from Selenium so

Answer 1

It's very simple, just change

Wait.Until(ExpectedConditions.ElementIsVisible(By.Id("content-section")));

to

Wait.Until(c => c.FindElement(By.Id("content-section")));
