I have come across a few people with the same issue that seemed to have solved the problem with System.addProperty(\"webdriver.chrome.driver\", \".../chromedriver.exe\");<
System.addProperty(\"webdriver.chrome.driver\", \".../chromedriver.exe\");<
Install Selenium.WebDriver.ChromeDriver from NuGet and then you can do the following:
Selenium.WebDriver.ChromeDriver
IWebDriver driver = new ChromeDriver(Environment.CurrentDirectory);
