Vb.net code for selenium implicit wait

Question

I have had no success with getting a simple line of code to implement the selenium implicit wait. Can you send me to a reference? The C# version is unworkable. Here is the C# code.
using (IWebDriver driver = new FirefoxDriver())
{
driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(10);
driver.Url = "http://somedomain/url_that_delays_loading";
IWebElement myDynamicElement = driver.FindElement(By.Id("someDynamicElement"));
}

What I have tried:

Extensive search of the internet. Only can find code for C# and Java.

Can you post the C# version, i've done a bunch of work with selenium and have found a wait function that works for me but I don't know what you mean by "implicit wait"

David I added the code to the question. There doesn't seem to be much use of Selenium with vb.net.

So it looks to me you are trying to wait until something on the page loads correct? Or rather, you want selenium to wait until it can see whatever is on the page before it begins...ex: You want selenium to wait until it can see/interact with "someDaynamicElement" right?

I think you may want to look into WebDriverWait class in selenium. I mostly work with selenium in C# so hopefully this code is correct in VB.net (i didn't test it).

First i'll start with the C# example

C#

var wait = new WebDriverWait(driver, new TimeSpan(0, 0, 45));
wait.IgnoreExceptionTypes(typeof(StaleElementReferenceException));
			
wait.Until(webDriver =>
{
	return webDriver.FindElements(By.Id("someDynamicElement")).Where(m => m.Displayed).Any();
});

So the idea is that wait.Until will continue to loop until a condition is met that is true (the xml doc on this method is stupid, it says "until a condition is neither null nor false"...so until its true).

Also, you give it a max timeout of 45 seconds so if it finds what it needs in 2 seconds, great, if it takes 10 seconds then thats fine too...you don't have to require selenium to wait X number of seconds unnecessarily is the idea.

So converting it to vb.net i think would be something like this.

VB.NET

Dim wait As New WebDriverWait(webDriver, TimeSpan.FromSeconds(seconds))
wait.Until(Function(webDriver)
  Return webDriver.FindElement(By.Id("someDynamicElement")).Enabled And webDriver.FindElement(By.Id("someDynamicElement")).Displayed
End Function)

The only downside to this is that on every page load you'll need to use the above sample for at least the first element so that way you don't have to resort to a Thread.Sleep or something like that.
