Selenium - start your normal chrome and not chromium

im looking example how can i start my normal google chrome in webdriver c#?
For now i use :
ChromeDriver driver;
public ChromeDriverService chromeDriverService;
chromeDriverService = ChromeDriverService.CreateDefaultService();
chromeDriverService.HideCommandPromptWindow = true;
var chromeOptions = new ChromeOptions();
chromeOptions.AddArguments("disable-infobars");
chromeOptions.AddExcludedArgument("enable-automation");
chromeOptions.AddAdditionalCapability("useAutomationExtension", false);
driver = new ChromeDriver(chromeDriverService,chromeOptions);
But it run my chromedriver.exe installed inside project. Can i just run my simple installed chrome? Without download any chromedriver.exe? It's important for me , because some website check if there is opened chromium with chromedriver.exe.
Is it possible to do that?

If you want not just open it but also perform some interaction with your site then you have to deal with Selenium and WebDriver.
You can try Python and undetected-chromedriver which has some workarounds preventing some systems to detect that your browser is running under webdriver control.

Unfortunately, it's the chromedriver.exe that lets you interact with Chrome so, without the driver, you wouldn't be able to interact with the actual browser.
If your issue is with chromium, try driving Mozilla with GeckoDriver

Selenium always uses chromedriver.exe for interacting with Chrome, I think you mean you want to load your default data directory. You can add a chrome option for this purpose:
chromeOptions.AddArguments(#"C:\Users\<your user name>\AppData\Local\Google\Chrome\User Data")
Take care, any other chrome must not be running that time with the same data directory. Like you may have run for your personal use.
You can also create a data directory somewhere else if you just want to show some realistic behavior to a website. But some websites are smart enough so it does not work every time.

Use Selenium to attach to a manually opened Browser

I know, that such a question is already asked here before, but it is 4 years old and not quite helpful.
So, what i want to do is simple, i want my selenium (running in WPF and .Net 5.0 in c#) so connect to an open browser to control it. The browser is opened manually with the debuggingport 9222 and i can successfull connect to this browser from another browser instance.
i am able to open a NEW Chrome browser with selenium and control it, but i need to also have the ability to connect to an open instance.
and help would be awesome.
PS: i know that selenium is for testing, and normally not used to not be in a controlled test-environment. =)
thank you so much for you help guys.

Type : chrome://version/ in browser you will get executable path of chrome.exe
copy this and close all chrome instance.
**close all chrome instance and **
start chrome as:
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --remote-debugging-port=5555
verify chrome is started with port open by going to localhost:5555
Now add remote debugging port as:
var options = new ChromeOptions();
options.debuggerAddress= "127.0.0.1:5555";
var driver = new ChromeDriver(options);
use chrromeoptions to connect to that port from selenium

Is there any way to hide chrome selenium?

I have tried
options.add_argument("--headless")
driver = new ChromeDriver(options)
it's working fine but my requirement is to hide it after initialization.

As you can see here: How to execute tests with selenium webdriver while browser is minimized there is no way for the browser to be minified.
You could in theory move the browser out of view as described here https://sqa.stackexchange.com/questions/15484/how-to-minimize-the-browser-window-which-was-launched-via-selenium-webdriver
driver.manage().window().setPosition(new Point(-2000, 0))
Chrome headless is an instance of chrome. You can't start from normal mode and switch to headless mid test. Once you start testing with any kind of browser mode, you need to stick to it. There are some work arounds I've not tried with opening windows with code and continuing from the new window.

Use phantomJSDriver for Headless automation
WebDriver driver = new PhantomJSDriver();

Selenium, how to take screenshot without opening the browser?

I want to take a screenshot of a webpage using Selenium.
I have notice that the action to take the screenshot require to open the web browser itself.
tried to change webDriver.Navigate().GoToUrl("http://www.google.com"); with webDriver.Url = "http://www.google.com"; but no success,
I even tried to leave it with no url and the browser opened with url of 'data', which now I understand that something else makes the browser to be open.
private void button1_Click(object sender, EventArgs e)
{
var capabilitiesInternet = new
OpenQA.Selenium.Remote.DesiredCapabilities();
capabilitiesInternet.
SetCapability("ignoreProtectedModeSettings", true);
IWebDriver webDriver = new ChromeDriver();
webDriver.Navigate().GoToUrl("http://www.google.com");
Screenshot screenshot = ((ITakesScreenshot)webDriver).GetScreenshot();
screenshot.SaveAsFile("E:\\ScreenShot.png",
System.Drawing.Imaging.ImageFormat.Png);
webDriver.Quit();
}

No - you need to let the WebDriver request the page, otherwise how can it know what screenshot to produce?
If you're trying to avoid a real, 'slow' browser starting up and opening a window, you should either consider running that browser headlessly, as per:
How do I run Selenium in Xvfb?
Or check out the headless WebKit browser PhantomJS (or maybe SlimerJS), and using almost exactly the same WebDriver API as you have now, ask it to produce your screenshots 'in-memory':
Phantomjs - take screenshot of a web page
Just replace:
WebDriver webDriver = new ChromeDriver();
with:
WebDriver webDriver = new PhantomJSDriver();
(Obviously requires the application to be installed locally)
Edit: Just a note that the typical use-case for this is 'overnight' continuous-integration / continuous-testing when run from headless CI servers. However, it can be very easily added to other work-flows, e.g. for visual regression-testing, and simple one-off checks.

There's multiple ways to go about it:
There is chrome flag --no-startup-window which should open chrome without window. I tried it, and it didn't work, however, you can give it a go.
Use hacks - there is a way to start chrome without you ever seeing it, it works nicely. Just use --window-position=-9999,0, note that, TakeScreenShot() has some weird anomalies in my experience - it focuses the window, it runs out of memory randomly, etc. What I ended up doing is I wrote chrome extension which can take screenshots and return them back to selenium through JS.

Selenium C# Webdriver IE11 issues

I am struggling through what appear to be issues with WebDriver properly interacting with the Internet Explorer Server (IE11). I have quite a number of tests already authored and working in Chrome but when I try to run the exact same tests using the latest IE Driver server (2.46.0 - downloaded from http://www.seleniumhq.org/download/)
I have read a number of articles on setting up a registry entries and adding my site to the list of trusted sites to to possibly handle a few of these issues but I have been un-successful (Selenium WebDriver on IE11)
Within the page above, one of the responses links to a Microsoft site for downloading IE Web Driver for IE 11 (http://www.microsoft.com/en-us/download/details.aspx?id=44069), this link wants to download and install something.
My question: Is there a difference in the WebDriver from the Selenium site versus the MS site?
Thanks
Sean

Try disabling the native event for IE shown as follows
var options = new InternetExplorerOptions { EnableNativeEvents = false };
options.AddAdditionalCapability("disable-popup-blocking", true);
Driver = new InternetExplorerDriver(options);
Also, DesireCapabilities expands the ability of controlling driver instance more.
