I’m using the namespaces below and you still don’t recognize.

OpenQA.Selenium;
OpenQA.Selenium.Chrome;
System.Threading;
Selenium.WebDriver.WaitExtensions;
OpenQA.Selenium.Support.UI;

Answer 1

I managed to resolve personal. I manually imported the dll from Openqa.Selenium.Support.UI and resolved it. Downloading by Nuget did not work.
