C# Selenium Chromedriver only shows 'data'

I created a very simple C# project to test Selenium and Chrome Driver, but when I run it, it gets stuck at the very first line, ie. creating ChromeDriver object.
I have set up as following:
.NET Core 3.1 console app (also tried .NET 4.7)
Installed Selenium.WebDriver 3.141.0 and Selenium.WebDriver.ChromeDriver 87.0.4280.8800.
My Chrome version is "Version 87.0.4280.88 (Official Build) (64-bit)". I have double-checked compatibility with Chrome and ChromeDriver.
Code:
using OpenQA.Selenium.Chrome;
namespace MyFirstSelenium
{
class Program
{
static void Main(string[] args)
{
ChromeDriver chrome = new ChromeDriver();
chrome.Navigate().GoToUrl("https://www.google.co.jp/");
}
}
}
visual studio screen
chromedriver.exe is copied to the debug folder as expected, so I assume the problem is neither compatibility nor path.
chromedriver
When I run the code, the result is an empty window with 'data' in the address bar. No error is thrown. I have searched for several hours and found some articles, but most of them are old and none of these answers led to success.
Any help is appreciated. Thank you.
Added chromedriver.exe verbose console output.

New code
Works when I first execute "chromedriver.exe --verbose --log-path=chromedriver.log", but without it, it throws WebDriverException.
OpenQA.Selenium.WebDriverException: 'A exception with a null response was thrown sending an HTTP request to the remote WebDriver server for URL localhost:9515/session. The status of the exception was UnknownError, and the message was: No connection could be made because the target machine actively refused it. No connection could be made because the target machine actively refused it.'
var chromeOptions = new ChromeOptions();
chromeOptions.BrowserVersion = "87";
IWebDriver driver = new RemoteWebDriver(new Uri("http://localhost:9515"), chromeOptions);

Possibly a classic case of cyclic redundancy.
chrome is a reserved word, you may have to change the variable name to something else e.g. chromex. So your effective line of code will be:
ChromeDriver chromex = new ChromeDriver();
Additional Consideration
Consider the following aspects aswell:
Instead of using the ChromeDriver class use the IWebDriver interface.
IWebDriver driver = new ChromeDriver();
Instead of the partial url google.co.jp/ you need to pass the complete url through GoToUrl() as follows:
driver.Navigate().GoToUrl(#"https://www.google.co.jp/");

C# Google Chrome Selenium URL Navigation with BinaryLocation

Greetings StackOverflow Community,
My issue is simple. I have the following five lines of code, that I can't figure out why Google Chrome doesn't launch google.com when using a custom binary location.
var Chrome = new ChromeOptions();
Chrome.AddArgument("no-sandbox");
Chrome.BinaryLocation = #"C:\GoogleChrome\chrome.exe";
ChromeDriver driver = new ChromeDriver(#"C:\ChromeDriver", Chrome);
driver.Navigate().GoToUrl("https://www.google.com");
Any ideas? All I get is the default chromedriver URL of "data:," when Google Chrome launches.
Why isn't the driver.navigate command working when using a Chrome.BinaryLocation? If I comment out that line, than it works fine.
I am using the following:
Windows 7
Visual Studio Community Edition 2017
Google Chrome version 67
chromedriver 2.41
.NET 4.5 Bindings

hey i dont think you need of binary location
And maybe Chrome is already a type,
try this:
ChromeOptions options = new ChromeOptions();
options.AddArgument("no-sandbox");
var driver = new ChromeDriver(#"C:\GoogleChrome", options);
driver.Navigate().GoToUrl("https://www.google.com");

Okay, I found the answer to this question. I don't know why the Portable version of either Firefox, Chrome or other Chromium based browsers do not function this way, but I resolved this issue by copying the enterprise installation files from program files for Chrome to another directory on the computer and then pointing the Selenium script to use that binary location. Then it worked just fine.
It was also useful to point Chrome to a custom chrome profile location to keep more of the Chrome application from using the local users's AppData folder.
If anyone is interested in accomplishing the same task, I can provide some example code that accomplishes this task. Just message me for more details.

System.InvalidOperationException occurred in WebDriver.dll while doing automation testing in Firefox driver

I have updated the latest selenium webdriver (v 3.4.0) installed and have latest firefox driver(0.15.0). I have these installed in a project which I am working on by "Manage Nuget Packages" option. Suddenly all of my tests are failing as it is not able to interact with any of the elements on firefox browser. To state about my issue, when I try the below simple tests on a google website
IWebDriver driver = new FirefoxDriver();
driver.Url = "https://www.google.com/";
var MyKeyWord = driver.FindElement(By.Id("lst-ib"));
MyKeyWord.SendKeys("Gmail");
it is failing with below exception.
An unhandled exception of type 'System.InvalidOperationException' occurred in WebDriver.dll
Additional information: Expected [object Undefined] undefined to be a string (IndexOutOfBounds)
I was searching on how to handle this problem and I found a solution as below:
driver = new FirefoxDriver(DRIVER_PATH);
But all my tests were executing without specifying these path in firefox earlier as firefox picks them when we install the required package using "Manage Nuget Packages" option. I am not sure why it started failing all of a sudden. Does someone have any suggestion on this?

Download latest geckodriver from https://github.com/mozilla/geckodriver/releases. Unzip it and put gecodriver file your system path. Restart (if needed) .
This link will help for setup : https://github.com/mozilla/geckodriver
I hope it will help.

There are two Chromedriver displays in NuGet manager - one driver for Chrome and other one is Selenium Google Chrome driver. You have to install both, then it works.

Selenium with Microsoft Edge driver never finishes initialising

I'm using the C# bindings for Selenium and trying to get a simple automated test in Microsoft Edge working.
class Program
{
static void Main(string[] args)
{
EdgeOptions options = new EdgeOptions();
options.PageLoadStrategy = EdgePageLoadStrategy.Eager;
RemoteWebDriver driver = new EdgeDriver();
driver.Url = "http://bing.com/";
}
}
But the program halts on the initialisation of the EdgeDriver, the edge browser launches but the url never changes to "bing.com".
Has anyone else experienced this?

I have faced the same issue. I followed the below steps to resolve it :-
Download the correct Microsoft WebDriver server version for your build.
How to find your correct build number :-
1- Go to Start > Settings > System > About and locate the number next to OS Build on the screen. This is your build number. Having the correct version of WebDriver for your build ensures it runs correctly.
2- Run this command systeminfo | findstr /B /C:"OS Version" this will give the output like OS Version: 10.0.10586 N/A Build 10586. Here is build number is 10586
You need to check your Windows OS build number and download appropriate .msi and install it.
Provide the Syetem property where MicrosoftWebDriver.exe installed to webdriver.edge.driver.
Note :- The Default installed location of the MicrosoftWebDriver.exe :-
for 64 bit is C:\Program Files (x86)\Microsoft Web Driver
for 32 bit is C:\Program Files\Microsoft Web Driver
Hope it will work...:)

This happens when your system does not match the webdriver version... Determine which release of Windows 10 you are using... then go here and download same release..
https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver
Here's what the error looks like when the versions don't match.
Selenium will Hang
EdgeOptions options = new EdgeOptions();
options.PageLoadStrategy = EdgePageLoadStrategy.Eager;
RemoteWebDriver driver = new EdgeDriver();
driver.Url = "http://bing.com/";
Results in this exception with Edge still up and on the Bing page
Exception Thrown
changing the code to this, with no options:
var driver = new EdgeDriver();
driver.Url = "http://bing.com/";
Results in this:
Exception thrown: 'System.InvalidOperationException' in WebDriver.dll
And this in the console.
Something's not right with the MicrosoftWebDriver.Exe which was downloaded from here. https://www.microsoft.com/en-us/download/details.aspx?id=48212 and installed into the Program Files folder by default. Here's screenshot of add/remove programs. System is Windows 10 PRO 64 bit.
Note I did not try the 32 bit version

Firefox 19 'support' was added in Selenium's latest versions. So since you are using .NET, the direct download for the latest at the time of this post is version 2.31.2:
selenium-release.storage.googleapis.com/index.html

I have this issue with Firefox 43 and Selenium 2.48.
It happens when your Selenium driver server is running in a 32 bit process and you start the 64 bit version of Firefox.
The cause is that the webdriver server tries to connect to port 7055 which should be opened by the webdriver that runs in the Firefox executable. But you can see in TcpView from www.sysinternals.com that Firefox does not open this port. So the driver waits until his timeout (45 seconds) elapses.
This happens even after turning off the Windows Firewall completely.
All posts that I found in internet do NOT help: Upgrade Selenium, downgrade Firefox, etc..
But after installing the 32 bit version of the same Firefox 43 it works. I see in TcpView how Firefox 32 bit opens the port correctly:
In my code I use
FirefoxProfile Prof = new FirefoxProfile();
FirefoxBinary Bin = new FirefoxBinary(sBrowserExe);
mDriver = new FirefoxDriver(Bin, Prof);
With sBrowserExe = "C:\Program Files\Mozilla Firefox 43\firefox.exe"
the 64 bit version of Firefox 43 is started and I get the timeout exception.
With sBrowserExe = "C:\Program Files (x86)\Mozilla Firefox 43\firefox.exe"
the 32 bit version of Firefox 43 is started and it works!
UPDATE: The developers from Firefox now broke Selenium support COMPLETELY. New Firefox versions from 48 upwards need a digital signature for all extensions to be installed.
https://wiki.mozilla.org/Addons/Extension_Signing
What I don't understand is why Selenium people cannot get a signature for the current Selenium driver??
Firefox version 47.0 has a bug that does not allow to use it with Selenium. This bug has been fixed in version 47.0.1.
Firefox versions from 48.0 and above do not install the old Selenium driver anymore. They must be automated with Marionette (= Gecko) driver.
The problem is that Marionette is still beta and has a lot of missing features so there is currently no solution to automate the new Firefox versions.
As you see here the new driver is full of bugs: https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette/WebDriver/status

If Upgrading Webdriver doesn't help you can downgrade FireFox that will solve issue.

Which version of Selenium IDE you are using? Try downgrading the Firefox version. The release notes of selenium IDE is mentioned in below link.
https://code.google.com/p/selenium/wiki/SeIDEReleaseNotes
Hope this helps.

Install all the updates in your Nuget package manager. Restart IDE.
Downgrading firefox version is not recommended for testing. But last but one version downgrade sounds good.
This solution worked for me.
