How to get Selenium to operate two browser windows using only one driver selenium (using c# and chromedriver)?

I am attempting to control two browser windows via selenium using c# and a single chromedriver. The reason being that I need to share session details accross browser windows.
The code that I have tried and failed with is below;
var options = new ChromeOptions();
options.AddArguments("chrome.switches", "--disable-extensions --disable-extensions-file-access-check --disable-extensions-http-throttling --disable-infobars --enable-automation ");
options.AddUserProfilePreference("credentials_enable_service", false);
options.AddUserProfilePreference("profile.password_manager_enabled", false);
options.PageLoadStrategy = PageLoadStrategy.Default;
ChromeDriverService service = ChromeDriverService.CreateDefaultService();
service.HideCommandPromptWindow = true;
var Driver = new ChromeDriver(service, options);
//THIS WILL OPEN A NEW WINDOW. BUT BECAUSE IT IS A NEW DRIVER DOES NOT WORK FOR SHARING SESSION DETAILS.
//var TestDriver = new ChromeDriver(service, options);
//TestDriver.Manage().Window.Maximize();
//THIS JUST OPENS UP A NEW TAB. NOT A NEW WINDOW (IT WOULD SEEM MOST DOCUMENTATION SUGGESTS THAT IT SHOULD)
IJavaScriptExecutor jscript = Driver as IJavaScriptExecutor;
jscript.ExecuteScript("window.open();", "google.com.au");
//TRY USING THE SEND KEYS TECHNIQUE. NOTHING HAPPENS
var test = Driver.FindElement(By.TagName("html"));
test.SendKeys(Keys.Control + "n");
test.SendKeys(Keys.Control + "t");
//TRY AGAIN USING THE SEND KEYS TECHNIQUE USING A DIFFERENT TAG. NOTHING HAPPENS
var blah = Driver.FindElements(By.TagName("body"));
blah[0].SendKeys(Keys.Control + "t");
//TRY USING ACTIONS. NOTHING HAPPENS
Actions action = new Actions(Driver);
action.SendKeys(OpenQA.Selenium.Keys.Control + "n");
action.Build().Perform();
I may resort to AutoIt to open a browser if I have to, but one more dependency is not what I need. Documentation everywhere around the web seems to suggest than all the options I tried above should work...I suspect it may be a chromedriver issue of some kind.
Any ideas on how to achieve my goal would be greatly appreciated
UPDATE.
Arnons answer below lead me to the solution. If you are in a similar situation the best thing to do is just open up the browser console (from developers tools) and experiment with javascript until you get what you want. Then just execute that. In the end executing the following code has worked for me.
IJavaScriptExecutor jscript = Driver as IJavaScriptExecutor;
jscript.ExecuteScript("window.open('https://www.bing.com.au','_blank','toolbar = 0, location = 0, menubar = 0')");
The other alternative was to use Autoit, which I also got working, much easier than I did figuring out the javascript. But one less dependency is best :)
UPDATE2.
Further complications arise with trying to control the window as an independent browser window. I believe any new window created from a parent window, has the same process id (at least my testing has indicated so), and for all intense and purpose is treated as a tab in the selinium driver. I therefore conclude that certain things are just not possible (for example relocating the child browser window on the screen).

Your first attempt using ExecuteJavaScript was very close, but In order for it to open a new window instead of new tab, you should add the following arguments: `"_blank", "toolbar=0,location=0,menubar=0" to it.
See this question for more details.

I should have read the question better, here is my solution. Ended up using this for selecting windows that popped up after clicking a button but should work with swapping between windows.
//---- Setup Handles ----
//Create a Handle to come back to window 1
string currentHandle = driver.CurrentWindowHandle;
//Creates a target handle for window 2
string popupWindowHandle = wait.Until<string>((d) =>
{
string foundHandle = null;
// Subtract out the list of known handles. In the case of a single
// popup, the newHandles list will only have one value.
List<string> newHandles = driver.WindowHandles.Except(originalHandles).ToList();
if (newHandles.Count > 0)
{
foundHandle = newHandles[0];
}
return foundHandle;
});
//Now you can use these next 2 lines to continuously swap
//Swaps to window 2
driver.SwitchTo().Window(popupWindowHandle);
// Do stuff here in second window
//Swap back to window 1
driver.SwitchTo().Window(currentHandle);
// Do stuff here in first window

You need to explicitly tell Selenium which tab you wish to interact with, which in this case would be;
driver.SwitchTo().Window(driver.WindowHandles.Last());

Adding ChromeOptions for Selenium Webdriver C#

From what I understand, the default action of when the Webdriver finds an element is to scroll such that the element is as far up the top of the page as possible. This is an issue because the website I'm working on has a header so every time I try to click on a button, it will instead click on the header. Thus, I want to change the scroll setting so that the element will be at the bottom of the page.
From reading this I was able to find what I wanted to set, however, I'm unable to set the DesiredCapabilites or ChromeOptions when I initialise the ChromeDriver. Could some provide code/steps to do this please?

You can use something like this
var chromeOptions = new ChromeOptions();
chromeOptions.AddUserProfilePreference("intl.accept_languages", "en");
chromeOptions.AddUserProfilePreference("disable-popup-blocking", "true");
var driver = new ChromeDriver(chromeOptions);
Edit-2
If the option you want to set doesn't work for you then try using actions
var elem = driver.FindElements(By.Id("your element"));
Actions action = new Actions(driver);
action.MoveToElement(elem).Click(elem).Perform();//move to list element that needs to be hovered
Edit-3
If the above also doesn't work then your next option is to use Javascript
var elem = driver.FindElements(By.Id("your element"));
IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
var success = js.ExecuteScript("arguments[0].click(); return true", elem);

As far as I know you can't change everything through addarguments.
There is a list of what you can do in the Github page. but I have a better solution. you can make your own default settings and save it as a chrome profile. for example I didn't find anything to change homepage with code but this works fine for almost evwerything.
you can use this code :
options.AddArguments( #"user-data -dir=C:\Users\kian\AppData\Local\Google\Chrome\User Data");
options.AddArgument("--profile-directory=Default");
make sure you write the right path and right profile name.
to check the profile name you can go to properties.
properties
you will see the profile name.
there is a good guide for what else u can do in link.

Nested Hover in Selenium C#

I am creating the test cases for my learning using Selenium C# in Orange Hrm application.
https://enterprise-demo.orangehrmlive.com/auth/login
Username and password: admin.
Once I login, there are differen menu, I am traversing through Admin>User Management>users and click on Users.
However, I am not getting way to how to use the MouseOver in Selenium C#.
Attached is the screenshot for your reference.enter image description here

From my limited knowledge you'll have to do it in a few steps.
Below is an example using NgWebDriver (angularJS app)
Actions builder = new Actions(ngDriver);
var elementToHover= ngDriver.FindElement(By.ClassName("dpcontract"));
builder.MoveToElement(elementToHover, 10 , 0)
builder.Build().Perform();
This builds a new action by finding the target element, moving the mouse to its position (x/y) with a 10 offset on the x (in my case).
You can add more events to that action trigger. The original (working) code for a drag and drop type-action i have is this
Actions builder = new Actions(ngDriver);
var elementToClick = ngDriver.FindElement(By.ClassName("dpcontract"));
builder.MoveToElement(elementToClick, elementToClick.Size.Width - 1, 0)
.ClickAndHold()
.MoveByOffset(150, 0)
.Release();
builder.Build().Perform();

Thank you Jens Stragier for your suggestion. Based on your suggestion, I wrote as follows and it worked for me.
Actions action = new Actions(Driver);
action.MoveToElement(elemWomen);
Thread.Sleep(500);
action.ClickAndHold(elemWomen);
action.Release(TShirt);
action.Click(TShirt);
action.Perform();

Switching tabs not working in Selenium Webdriver

I wrote this code in C# and it's not working for me.
Second url is still opening in the first tab, although I switched tabs and updated handle.
// open first page in first tab
string firstPageUrl = "http://google.com";
driver.Navigate().GoToUrl(firstPageUrl);
// getting handle to first tab
string firstTabHandle = driver.CurrentWindowHandle;
// open new tab
Actions action = new Actions(driver);
action.SendKeys(OpenQA.Selenium.Keys.Control + "t").Build().Perform();
string secondTabHandle = driver.CurrentWindowHandle;
// open second page in second tab
driver.SwitchTo().Window(secondTabHandle);
string secondPageUrl = "http://bbc.com";
driver.Navigate().GoToUrl(secondPageUrl); // FAILED, page is opened in first tab -.-
Thread.Sleep(2000); // slow down a bit to see tab change
// swtich to first tab
action.SendKeys(OpenQA.Selenium.Keys.Control + "1").Build().Perform();
driver.SwitchTo().Window(firstTabHandle);
Thread.Sleep(1000);
action.SendKeys(OpenQA.Selenium.Keys.Control + "2").Build().Perform();
I'm using latest Chrome driver.
Any ideas?
EDIT:
This is not duplicate. I am not opening links here, I want to navigate to URL I've provided. Also, I am using CurrentWindowHandle as suggested, but it is not working for me.

string secondTabHandle = driver.CurrentWindowHandle; is still returning the first tab, even if the second tab cover the first one. Try this
string firstTabHandle = driver.getWindowHandle();
Actions action = new Actions(driver);
action.SendKeys(OpenQA.Selenium.Keys.Control + "t").Build().Perform();
// switch to the new tab
for (String handle : driver.getWindowHandles()) {
if (!handle.equals(firstTabHandle))
{
driver.switchTo().window(handle);
}
}
// close the second tab and switch back to the first tab
driver.close();
driver.switchTo().window(firstTabHandle);

Not entirely sure if this is related to your problem (but I think it might be):
I've found, with selenium, that a better alternative to using Thread.Sleep() is using:
WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(15));
where first argument is the selenium driver you're using, and the second argument is how long you want to wait before giving up (the timeout)
You can then call:
wait.Until(condition);
where condition is what you want to wait for. There is a selenium class that provides various useful conditions called ExpectedConditions, for example:
ExpectedConditions.ElementToBeClickable(By by)
which would wait for a particular clickable element to be ready to click.
In fact, I've found that any time the content of the page changes, it's a good idea to wait for the element you're using next like this.

Selenium getting data from another tab instead of active one

We have a legacy remote system here that dont have webapi, webservice, ...
then we need to do integration by Selenium.
We need open multiple tabs from one master tab to do the extraction but when changing to desired tab and getting value by a css selector it get always the result from the fisrt tab.
Our system cant be opened on internet then i did the same with Google as an example, the same behaviour happens.
Its a bug or my fault ? Someone can see whats is wrong?
Below is a simplified version without error check, its minimal code.
Thanks a lot.
public static void testab()
{
IWebDriver driver = new FirefoxDriver();
driver.Navigate().GoToUrl("https://www.google.com/ncr");
IWebElement elmTxt = driver.FindElement(By.CssSelector("input#lst-ib"));
elmTxt.SendKeys("google" + Keys.Enter);
IWebElement elmQtdRes = driver.FindElement(By.CssSelector("div#resultStats"));
string strWebStat = elmQtdRes.Text;
IWebElement elmNewsLnk = driver.FindElement(By.CssSelector("a[href*='tbm=nws']"));
elmNewsLnk.SendKeys(Keys.Control + Keys.Return);
IWebElement elmBdy = driver.FindElement(By.CssSelector("body"));
elmBdy.SendKeys(Keys.Control + "2");
elmQtdRes = driver.FindElement(By.CssSelector("div#resultStats"));
string strNewStat = elmQtdRes.Text;
Console.WriteLine("Stat for WEB:[" + strWebStat + "]"); // prints stat for web - OK
Console.WriteLine("Stat for NEWS:[" + strNewStat + "]"); // prints stat for web - WRONG
}

WebDriver will not automatically switch focus to a new window or tab, so we have to tell it when to make the switch.
To switch to the new window/tab, try:
driver.SwitchTo().Window(driver.WindowHandles.Last());
Then, when you are finished on the new tab, close it and switch back to the primary window:
driver.Close();
driver.SwitchTo().Window(driver.WindowHandles.First());
Then from here, you can continue your test.
I'll add a quick disclaimer that I do not have Visual Studio installed on the machine I'm using at the moment and haven't tested the code above. This should, however get you in the right direction.
EDIT: Looking at your code a second time, this example above would replace the SendKeys() call to attempt to switch tab focus:
IWebElement elmBdy = driver.FindElement(By.CssSelector("body"));
elmBdy.SendKeys(Keys.Control + "2");
