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/");

Invalid server instance exception has occurred: There is no installed nodes! Please install node via NPM or download and install Appium

I'm using Appium + C# for mobile Automation and below is my pseudo-code:
AppiumLocalService _appiumLocalService = new AppiumServiceBuilder().UsingAnyFreePort().Build();
_appiumLocalService.Start();
var appiumOptions = new AppiumOptions();
appiumOptions.AddAdditionalCapability(MobileCapabilityType.DeviceName, ConfigurationManager.AppSettings["deviceName"]);
appiumOptions.AddAdditionalCapability(MobileCapabilityType.PlatformName, "Android");
appiumOptions.AddAdditionalCapability(MobileCapabilityType.PlatformVersion, ConfigurationManager.AppSettings["platformVersion"]);
appiumOptions.AddAdditionalCapability(MobileCapabilityType.NoReset, true);
appiumOptions.AddAdditionalCapability(MobileCapabilityType.App, ConfigurationManager.AppSettings["app"]);
appiumOptions.AddAdditionalCapability("appPackage", ConfigurationManager.AppSettings["appPackage"]);
appiumOptions.AddAdditionalCapability("appActivity", ConfigurationManager.AppSettings["appActivity"]);
appiumOptions.AddAdditionalCapability("newCommandTimeout", 5000);
appiumOptions.AddAdditionalCapability("autoLaunch", false);
_driver = new AndroidDriver<AppiumWebElement>(appiumOptions);
I'm getting the following error message:
{"Invalid server instance exception has occurred: There is no installed nodes! Please install node via NPM (https://www.npmjs.com/package/appium#using-node-js) or download and install Appium app (http://appium.io/downloads.html)"}
Below you can see which settings I have already installed

Try installing Appium with npm install -g appium.
Then try again.

Appium launching on real device but chrome hangs

I'm running Appium 1.6.1 on Windows 10, and I'm trying to automate Chrome on a real device (in this instance a Samsung Galaxy S7 running Android 7.0). I'm using C# and visual studio. My code looks like the below:
using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using OpenQA.Selenium.Appium;
using OpenQA.Selenium;
using OpenQA.Selenium.Remote;
using OpenQA.Selenium.Appium.Android;
namespace MobileBrowserTesting{
[TestClass]
public class UnitTest1{
AppiumDriver<IWebElement> Driver;
[TestMethod]
public void TestMethod1(){
DesiredCapabilities caps = new DesiredCapabilities();
caps.SetCapability("deviceName", "hero2lteskt");
caps.SetCapability("udid", "ce11160b3889d43005"); //Give Device ID of your mobile phone
caps.SetCapability("browserName", "Chrome");
//Launch the Android driver
Driver = new AndroidDriver<IWebElement>(new Uri("http://127.0.0.3:4723/wd/hub"), caps);
Driver.Navigate().GoToUrl("http://www.google.com");
string url = Driver.Url;
bool viewable = Driver.FindElement(By.Id("q")).Displayed;
}
}
}
Chrome launches, however it simply sits at "data;" with a blank screen and doesn't progress to the website. The last step in the Appium view is:
[JSONWP Proxy] Proxying [POST /session] to [POST
http://127.0.0.1:8001/wd/hub/session] with body: {"desiredCapabilities":
{"chromeOptions":
{"androidPackage": "com.android.chrome","androidDeviceSerial":"ce11160b3889d43005"}}}
[HTTP] <-- POST /wd/hub/session - - ms - -
And visual studio times out with the error message:
Message: Test method MobileBrowserTesting.UnitTest1.TestMethod1 threw
exception:
OpenQA.Selenium.WebDriverException: The HTTP request to the remote WebDriver server for URL http://127.0.0.3:4723/wd/hub/session timed out after 60 seconds. ---> System.Net.WebException: The operation has timed out
After a while Appium times out with:
[W3C] Encountered internal error running command: Error: Failed to start
Chromedriver session: An unknown server-side error occurred while processing
the command. (Original error: unknown error: Device ce11160b3889d43005 is
already in use
Appium is launched in admin mode, with "Allow session override" ticked under Advanced.
The chromedriver being used is the latest one (2.39) and the version of chrome on the device is 66.0.3359.158 so it should be compatible.
Any ideas why it seems to hang/not interact with Chrome?
Cheers in advance

web testing project in visual studio 2015 wont work, why?

I just started using visual studio 2015 & c# language so I'm a complete newbie. anyway I was trying to write a web testing project with selenium (references) in vs2015 and the first few tutorials were relatively easy to understand, that's what I got:
using System;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Support;
namespace testsite
{
[TestClass]
public class firsttest
{
IWebDriver driver;
String url = "http://www.somewabpage.com";
[TestInitialize]
public void setup()
{
//Starting the browser and visiting the site
driver = new ChromeDriver();
driver.Navigate().GoToUrl(url);
}
[TestCleanup]
public void Cleanup()
{
//after the test
driver.Quit();
}
[TestMethod]
public void testtingsite()
{
//Here we write the actual test
}
}
}
I know it's not much, but the problem is when ever I go to test explorer >> run all then I get this:
------ Run test started ------
Cannot discover test extensions installed by NuGet. The NuGet service is not available. Tests may not be found due to missing test adapter extensions.
NUnit VS Adapter 2.0.0.0 executing tests is started
Loading tests from C:\Users\kkkkkk\Documents\Visual Studio 2015\Projects\testsite\testsite\bin\Debug\testsite.dll

NUnit VS Adapter 2.0.0.0 executing tests is finished
========== Run test finished: 1 run (0:00:06.5556584) ==========
White it should open the chrome browse, visit the url and then quits chrome, which doesn't happen at all. I re-tested it again with the same result only this time it says in the test explorer window that the test has failed and that's it, when I click on the testsite below the failed test (still in the test explorer window) i get the following message :

okay that's the message, any ideas on how to solve the issue I really need help );
modification_1
so I've modified the code (thanks to #Leon) I added the following string DRIVER_PATH = #"C:\Projects\webdriver\dotnet\src\webdriver\chrome\chromedriver"; to [TestClass] right below the string url = "http://..."; and also add DRIVER_PATH like this driver = new ChromeDriver(DRIVER_PATH); in the [TestInitialize] but it's still not running the chrome browser!!?

You need download chrome driver.
chrome driver link
string DRIVER_PATH = #"C:\...\chromedriver";
IWebDriver driver = new ChromeDriver(DRIVER_PATH);
driver.Navigate().GoToUrl(url);

so the problem was like #leon mentioned it in the chromedriver, but although I used his path method (described in modification_1) it didn't work, what actually did work and solved my problem (without changing the first code, before mofication_1) was the installation of the selenium chromedriver from visual studio 2015, I went to references >> right click >> go to manage Nuget package >> and then typed selenium chromedriver in the search bar and boom all I had to do was click on install, internet connection was required. if you can't see the nuget manage packages then you need to download and install it and then restart visual studio to see it.

Just add the driver reference as per your browser specification like chromedriver, edgedriver. Please note "not mention any driver path".
