Add a Chrome extension to RemoteWebDriver using Selenium and C#

ChromeExtensionRemoteWebdriver.cs

        private IWebDriver GetRemoteDriver()
        {
            //1. Getting the path to my extension
            var outPutDirectory = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
            ChromeOptions options = new ChromeOptions();
            options.AddExtension(outPutDirectory + @"\3.1.3_0.crx");

            //2. Adding the appropriate capabilities
            //---- >>>> Don't do this - Setting the browser name is redundant
            //options.AddAdditionalCapability(CapabilityType.BrowserName, "chrome", true);
            options.AddAdditionalCapability(CapabilityType.Version, "48.0", true);
            options.AddAdditionalCapability(CapabilityType.Platform, "Windows 10", true);
            options.AddAdditionalCapability("username", "Buzzingha!", true);
            options.AddAdditionalCapability("accessKey", "flip-flop-please-just-stop", true);
            options.AddAdditionalCapability("name", TestContext.CurrentContext.Test.Name, true);

            //3. IMPORTANT - Notice the options.ToCapabilities() call!!
            return new RemoteWebDriver(new Uri("http://ondemand.saucelabs.com:80/wd/hub"), options.ToCapabilities(),
                TimeSpan.FromSeconds(600));
        }
