How to start ChromeDriver in headless mode

I want to try out headless chrome, but I am running into this issue, that I can't start the driver in headless mode. I was following google documentation. am I missing something ? The code execution gets stuck in var browser = new ChromeDriver(); line
Here is my code:
var chromeOptions = new ChromeOptions
{
BinaryLocation = #"C:\Users\2-as Aukstas\Documents\Visual Studio 2017\Projects\ChromeTest\ChromeTest\bin\Debug\chromedriver.exe",
DebuggerAddress = "localhost:9222"
};
chromeOptions.AddArguments(new List<string>() {"headless", "disable-gpu" });
var browser = new ChromeDriver(chromeOptions);
browser.Navigate().GoToUrl("https://stackoverflow.com/");
Console.WriteLine(browser.FindElement(By.CssSelector("#h-top-questions")).Text);

UPDATE
Chrome version 60 is out so all you need to do is to download Chromdriver and Selenium via Nuget and use this simple code and everything works like a charm. Amazing.
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
...
var chromeOptions = new ChromeOptions();
chromeOptions.AddArguments("headless");
using (var browser = new ChromeDriver(chromeOptions))
{
// add your code here
}
DATED
There is a solution until the official release of Chrome 60 will be released. You can download Chrome Canary and use headless with it. After installation set BinaryLocation to point to chrome canary also comment out the DebuggerAddress line(it forces chrome to timeout):
var chromeOptions = new ChromeOptions
{
BinaryLocation = #"C:\Users\2-as Aukstas\AppData\Local\Google\Chrome SxS\Application\chrome.exe",
//DebuggerAddress = "127.0.0.1:9222"
};
chromeOptions.AddArguments(new List<string>() { "no-sandbox", "headless", "disable-gpu" });
var _driver = new ChromeDriver(chromeOptions);

For you that did not get reference for ChromeDriver.
Use this step :
Download the dll from this: http://seleniumtestings.com/selenium-download/
Extract, and you should see: Selenium.WebDriverBackedSelenium.dll, ThoughtWorks.Selenium.Core.dll, WebDriver.dll and WebDriver.Support.dll
Add those files via "Add Reference"
Now you can use it:
String url = "http://www.google.com";
var chromeOptions = new ChromeOptions();
chromeOptions.AddArguments(new List<string>() {
"--silent-launch",
"--no-startup-window",
"no-sandbox",
"headless",});
var chromeDriverService = ChromeDriverService.CreateDefaultService();
chromeDriverService.HideCommandPromptWindow = true; // This is to hidden the console.
ChromeDriver driver = new ChromeDriver(chromeDriverService, chromeOptions);
driver.Navigate().GoToUrl(url);
====
If after you run, you are still facing error about no ChromeDriver.exe file, try to add the Selenium.WebDriver.ChromeDriver, WebDriver.ChromeDriver, WebDriver.ChromeDriver.win32, Selenium.Chrome.WebDriver via nuget.

As alternative:
Add 2 libraries via NuGet like below picture.
Try below Code:
String url = "http://www.google.com";
var chromeOptions = new ChromeOptions();
chromeOptions.AddArguments(new List<string>() { "headless" });
var chromeDriverService = ChromeDriverService.CreateDefaultService();
ChromeDriver driver = new ChromeDriver(chromeDriverService, chromeOptions);
driver.Navigate().GoToUrl(url);

What OS you're running? I see on developers.google.com/web/updates/2017/04/headless-chrome that headless won't be available on Windows until Chrome 60.

Below i have given how to set the headless to true for firefox and chrome browsers.
FirefoxOptions ffopt = new FirefoxOptions();
FirefoxOptions option = ffopt.setHeadless(true);
WebDriver driver = new FirefoxDriver(option);
ChromeOptions coptions = new ChromeOptions();
ChromeOptions options = coptions.setHeadless(true);
WebDriver driver = new ChromeDriver(options);

WebDriver Portable Firefox c#

I tried to load Portable Firefox
FirefoxProfile profile = new FirefoxProfile();
var binary = new FirefoxBinary(Directory.GetCurrentDirectory()+ #"\FirefoxPortable64\FirefoxPortable.exe");
var driver = new FirefoxDriver(binary, profile);
But i get error Unable to find a matching set of capabilities in line var driver = new FirefoxDriver(binary, profile);
can u help me pls ?
And in line var driver = new FirefoxDriver(binary, profile); i have warning:
FirefoxDriver should not be constructed with a FirefoxBinary object. Use FirefoxOptions instead. This constructor will be removed in a future release.
how i can rewrite the code ?
UPD:
I rewrite code:
FirefoxProfile profile = new FirefoxProfile();
FirefoxOptions options = new FirefoxOptions();
options.Profile = profile;
options.BrowserExecutableLocation = Directory.GetCurrentDirectory() + #"\FirefoxPortable64\FirefoxPortable.exe";
var driver = new FirefoxDriver( options);
But it doesnt work, again have error Unable to find a matching set of capabilities

Solution ;
options.BrowserExecutableLocation = Directory.GetCurrentDirectory() + #"\FirefoxPortable32\App\Firefox\firefox.exe";

Unable to instantiate Marionette driver with both a FirefoxProfile & FirefoxDriverService

I am currently updating my C# solution with the new Marionette driver for Firefox.
I have managed to get the driver to successfully launch a url with the following code
FirefoxDriverService service = FirefoxDriverService.CreateDefaultService(Directory.GetCurrentDirectory(),"wires-0.6.0-win.exe");
service.FirefoxBinaryPath = #"C:\Program Files (x86)\Mozilla Firefox\firefox.exe";
FirefoxDriver driver = new FirefoxDriver(service);
driver.Navigate().GoToUrl("http://www.google.com");
However i need to add a profile to the driver at initialisation in order to set the proxy. I was previously doing this like the following (for older Firefox versions).
private static IWebDriver InitialiseFirefoxDriver(Proxy proxy)
{
FirefoxProfile profile = new FirefoxProfile();
if (proxy != null)
{
profile.SetProxyPreferences(proxy);
}
return new FirefoxDriver(profile);
}
Unfortunately the FirefoxDriver constructor only allows me to pass in either a FirefoxDriverService or a FirefoxProfile. Does anybody know of a way that i can manage to give the driver both sets of config information before creating the driver (or even after)?
Thanks.

This is example code use FirefoxProfile & FirefoxDriverService. I want hide CommandPromptWindow and Mute.
FirefoxDriverService service = FirefoxDriverService.CreateDefaultService();
service.HideCommandPromptWindow = true;
FirefoxProfile _Profile = new FirefoxProfile();
_Profile.SetPreference("media.volume_scale", "0.0");
FirefoxOptions option = new FirefoxOptions();
option.Profile = _Profile;
var driver = new FirefoxDriver(service,option,TimeSpan.FromSeconds(20));
driver.Navigate().GoToUrl("https://www.youtube.com/watch?v=hxiitzCKRek");

How can I add profile preferences to Chrome for Selenium Grid 2 in C#?

This is how I add profile preferences to Chrome for Local Auto-test runs and TeamCity(CI):
Capabilities = DesiredCapabilities.Chrome();
var chromeOptions = new ChromeOptionsWithPrefs();
chromeOptions.AddUserProfilePreference("download.default_directory", DownloadPath);
chromeOptions.AddUserProfilePreference("intl.accept_languages", "nl");
chromeOptions.AddUserProfilePreference("disable-popup-blocking", "true");
return new ChromeDriver(chromeDriverPath, chromeOptions);
But when I create new 'RemoteWebDriver', I must send it a hub URL and 'Capabilities', this way I send profile preferences to Firefox (to RemoteWebDriver):
var profile = new FirefoxProfile();
Capabilities = DesiredCapabilities.Firefox();
profile.SetPreference("browser.helperApps.alwaysAsk.force", false);
profile.SetPreference("browser.download.useDownloadDir", true);
profile.SetPreference("browser.download.folderList", 2);
profile.SetPreference("browser.download.dir", DownloadPath);
profile.SetPreference("browser.helperApps.neverAsk.saveToDisk",
"application/zip, application/octet-stream");
Capabilities.SetCapability(FirefoxDriver.ProfileCapabilityName, profile.ToBase64String());
return Capabilities;
Can someone help me, I need to do the same thing to Chrome as I did to Firefox. Basically what I need, is that I could change the default path for downloading files.

You'll want to do something like the following:
var chromeOptions = new ChromeOptions();
chromeOptions.AddUserProfilePreference("download.default_directory", DownloadPath);
chromeOptions.AddUserProfilePreference("intl.accept_languages", "nl");
chromeOptions.AddUserProfilePreference("disable-popup-blocking", "true");
IWebDriver driver = new RemoteWebDriver(new Uri("http://path/to/selenium/server"), chromeOptions.ToCapabilities());

Selenium Firefox Profile Path not taken into account

I just want to test locally. With Internet Explorer it works. With Firefox, I get a timeout on line driver.FindElement :
var capabilitiesInternet = new OpenQA.Selenium.Remote.DesiredCapabilities();
capabilitiesInternet.SetCapability("ignoreProtectedModeSettings", true);
IWebDriver driver = new FirefoxDriver();
driver.Navigate().GoToUrl(url);
WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
IWebElement category = wait.Until<IWebElement>((d) =>
{
return d.FindElement(By.Name("login"));
});
// Login
driver.FindElement(By.Name("login")).SendKeys("test");
Error message is httpRequest to remotedriver timeout.
Upate: I think it's due to the fact that I have a portable version of Firefox 21 and an older version of FF which cannot work with Selenium whereas Selenium launch old version. So I tried to indicate the path of portable :
var capabilitiesInternet = new OpenQA.Selenium.Remote.DesiredCapabilities();
capabilitiesInternet.SetCapability("ignoreProtectedModeSettings", true);
string path = #"C:\Portable";
FirefoxProfile ffprofile = new FirefoxProfile(path);
IWebDriver driver = new FirefoxDriver(ffprofile);
Unfortunately it keeps running the old version (I cannot change the old version because of corporate environment).
Is there anyway to make this profile work ?

Not sure if it is your problem, but in order to 'point' Selenium to where Firefox is located, you are looking for the FirefoxBinary class:
var binary = new FirefoxBinary("pathtofirefox");
string path = #"C:\Portable";
FirefoxProfile ffprofile = new FirefoxProfile(path);
var driver = new FirefoxDriver(binary, profile);
