### C#: First Script - Complete Example

Source: https://www.selenium.dev/documentation/webdriver/drivers

This C# example demonstrates a basic Selenium WebDriver script: it creates a ChromeDriver, navigates to a web form, gets the title, sets an implicit wait, finds and interacts with a text box and submit button, retrieves a message, and quits the driver.

```csharp
using System;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

namespace SeleniumDocs.GettingStarted;

public static class FirstScript
{
    public static void Main()
    {
        IWebDriver driver = new ChromeDriver();

        driver.Navigate().GoToUrl("https://www.selenium.dev/selenium/web/web-form.html");

        var title = driver.Title;

        driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromMilliseconds(500);

        var textBox = driver.FindElement(By.Name("my-text"));
        var submitButton = driver.FindElement(By.TagName("button"));
            
        textBox.SendKeys("Selenium");
        submitButton.Click();
            
        var message = driver.FindElement(By.Id("message"));
