Is there any way to maximize the browser window using WebDriver (Selenium 2) with C#?
driver.Manage().Window.Maximize();
This works for IE and Firefox. Chrome does not work. There is a bug submitted for this on ChromeDriver project.
Meanwhile, the get around for the chrome is to implement what Joey V. and Coder323 suggested.
ChromeOptions options = new ChromeOptions();
options.addArgument("--start-maximized");
driver = new ChromeDriver(options);
