Cannot find WebDriverWait class in OpenQA.Selenium (C#)

(Migrating from Java-Selenium to C#-Selenium)

When searching for explicit waits with Selenium and C# I find several posts with code that looks similar to the Java-Counterpart:

for example here:

WebDriverWait wait = new WebDriverWait(driver, new TimeSpan(0,0,5));
wait.Until(By.Id("login"));

or here:

WebDriverWait wait = new WebDriverWait(driver, 30);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("locator")));

WebDriverWait are from the OpenQA.Selenium.Support.UI namespace and comes in a separate package called Selenium WebDriver Support Classes

BUT:
When I try to code this myself in Visual Studio (getting Selenium package via NuGet), using WebDriverWait in my code will prompt the message:

The type or namespace name 'WebDriverWait' could not be found (are you missing a using directive or an assembly reference?)

Even though I am including the Selenium reference via

using OpenQA.Selenium;

When looking up the documentation for WebDriverWait you will find, that there should be a namespace called

OpenQA.Selenium.Support.UI

But I cannot access it via "using" in my code.

Why does this happen? Where can I find the WebDriverWait class?

Luckily I sometimes read the comments to answers as well, so I stumbled across the solution within the highest ranked comment here:

WebDriverWait [is] from the OpenQA.Selenium.Support.UI namespace and comes in a separate package called Selenium WebDriver Support Classes on NuGet

Thanks @Ved!

In Visual Studio this means, that you need to install TWO packages:

  • NuGet package "Selenium.WebDriver" AND ALSO
  • NuGet package "Selenium.Support"

Coming from Java with Maven, this is not trivial (at least to me ;-), because until now I just needed to include one and only one dependency to get "all of the good stuff" like this:

<dependency>
    <groupId>org.seleniumhq.selenium</groupId>
    <artifactId>selenium-java</artifactId>
    <version>2.46.0</version>
</dependency>

* Posted this as a question including the answer because it cost me too much time and luck to stumble over the answer.

Have you tried adding?

using OpenQA.Selenium.Support.UI;

That should be all you need. Depending on your IDE, it likely (?) will have a helper that will find and add missing references. I use Visual Studio. I just type what I know should be there. When the IDE puts red squiggles on WebDriverWait, I hover over it and it shows a tooltip that says I'm missing a reference and I click on the link, Show potential fixes. In the new tooltip it shows several options, usually the first of which is to add the using statement. I click that one and the red squiggles go away.

I really like Visual Studio but I've been using Eclipse for the last 9 months or so and I prefer the way Eclipse handles this. I think it's more intuitive... but that's just me.

EDIT

Just wanted to make clear for future readers... I don't use NuGet. I just download the Selenium .Net package and drop the 4 DLLs in/near my project and then add references to all 4 of them to my Visual Studio project. Once I do that and use the instructions above, it works for me.

WebDriverWait is not available in OpenQA.selenium. Its Available SeleniumExtras.WaitHelpers

    using OpenQA.Selenium;
    using SeleniumExtras.WaitHelpers;
        
    WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
  wait.Until(SeleniumExtras.WaitHelpers.ExpectedConditions.ElementIsVisible(By.Id("Test")));
