Eu segui os passos de "Componentes de selênio para teste de navegador cruzado de interface do usuário codificado".

Mas eu baixei a versão mais recente de:

WebDriver.ChromeDriver.win32 2.4.0http://www.nuget.org/packages/WebDriver.ChromeDriver.win32/

selenium-dotnet-strongnamed-2.37.0https://code.google.com/p/selenium/downloads/list

então eu instalei aqueles na minha máquina de 64bits mas o Visual Studio 2013 apresenta o próximo problema quando tento rodar o teste automatizado:

System.IO.FileNotFoundException: Could not load file or assembly 
'WebDriver, Version=2.35.0.0, Culture=neutral, PublicKeyToken=1c2bd1631853048f' or one of its dependencies. The system cannot find the file specified.WRN: Assembly binding logging is turned OFF.
    To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
    Note: There is some performance penalty associated with assembly bind failure logging.
    To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
