Configure its polling interval or ignored exceptions when the condition warrants it. In .NET, Selenium’s WebDriverWait is the configurable wait; you do not need Java’s FluentWait syntax.
Write an explicit wait with WebDriverWait
An explicit wait repeatedly evaluates a specific condition and continues when it succeeds or stops when the timeout expires. The Selenium guide’s C# dynamic-page example is:

IWebElement revealed = driver.FindElement(By.Id("revealed"));
driver.FindElement(By.Id("reveal")).Click();
var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(2));
wait.Until(d => revealed.Displayed);
revealed.SendKeys("Displayed");The predicate passed to Until is checked repeatedly. Here it returns true only when the element is displayed, so the test sends text after the desired state is reached. The two-second timeout is the documentation example, not a universal setting; choose a limit appropriate to the operation and test environment. See Selenium’s Waiting Strategies guide.

Make the predicate represent the actual condition needed by the next command—for example, visibility before interacting with an element, or expected text before asserting it. A timeout does not make a slow or broken page ready; it means the condition did not become true within the configured limit. Keep the condition specific enough that a successful result really permits the next step.

Configure polling, ignored exceptions, and timeout messages
Selenium’s C# guide demonstrates setting the polling interval and ignoring an exception type:
var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(2))
{
PollingInterval = TimeSpan.FromMilliseconds(300),
};
wait.IgnoreExceptionTypes(typeof(ElementNotInteractableException));
wait.Until(d =>
{
revealed.SendKeys("Displayed");
return true;
});Configure exception handling carefully. Ignore an exception only when retrying the condition is sensible; otherwise, the wait can hide a genuine failure. The predicate should return success only after the intended state or action has succeeded. In this example, true is returned after SendKeys completes, not before.
The .NET wait API also exposes a timeout message, timeout, polling interval, and ignored-exception configuration. Consult the DefaultWait<T> API and WebDriverWait API for the members available to your installed package.
What “fluent wait” means in Selenium .NET
“Explicit wait” describes waiting for a named condition. “Fluent” commonly describes configuring how a wait behaves, such as its timeout, polling interval, and exceptions to ignore. Selenium’s .NET WebDriverWait derives from DefaultWait<IWebDriver>, and the official C# example configures WebDriverWait directly. Use that .NET API rather than copying Java examples that construct FluentWait or call methods such as withTimeout.
Selenium’s current Expected Conditions page says that .NET stopped supporting its built-in Expected Conditions in Selenium 4 to reduce maintenance and redundancy. Use predicates with Until, as above, unless your project deliberately includes a separately verified library. Details are on Selenium’s Expected Conditions page.
Choose explicit waits over a global implicit wait for dynamic states
| Approach | How it behaves | When it fits |
|---|---|---|
| Implicit wait | Applies globally to element-location calls for the session. Selenium’s default is zero. | It is a broad setting, not a wait for a particular visible state, text, or action. |
| Explicit wait | Polls a predicate at the point where the condition is needed; its timeout, polling, and exception behavior can be configured. | Use it for a specific dynamic condition such as an element becoming visible or text appearing. |
| Fixed sleep | Always pauses for the chosen duration and does not check whether the needed state has occurred. | Reserve it for a genuinely required fixed pause, not general page readiness. |
Avoid combining implicit and explicit waits in one session. Selenium warns that their interaction can make elapsed time unpredictable: its example notes that a 10-second implicit wait combined with a 15-second explicit wait can time out after 20 seconds. Prefer explicit waits for particular dynamic conditions and avoid a competing implicit wait. See the official guidance.
Version and API notes for C#
- The current Selenium C# wait example uses
TimeSpanto set the timeout. - A Selenium 4 upgrade page discusses Duration-based wait API changes, but that excerpt does not establish a corresponding .NET API change. Do not infer a C# migration requirement from another language’s API; check the API for your installed .NET package and target version. See Selenium’s Selenium 4 upgrade guide.
- Built-in Expected Conditions are not supported in .NET Selenium 4; a C# predicate passed to
Untilis the documented approach.
Troubleshoot waits that time out or finish too soon
- The wait times out: identify which predicate failed and whether the page reached the expected state. A timeout is a bound, not a guarantee that loading will finish.
- The next interaction still fails: check that the predicate tests the state required for that interaction and returns success only after that state is present.
- The delay is longer than expected: look for an implicit wait configured elsewhere in the session; Selenium warns that mixing it with explicit waits produces unpredictable total timing.
- An exception appears during polling: ignore it only if retrying that condition is appropriate. Otherwise let the failure surface instead of masking it.
- Expected Conditions examples do not compile: .NET no longer includes Selenium’s built-in Expected Conditions in Selenium 4. Replace them with a predicate or verify the separate dependency your project intends to use.
- A Java wait example does not compile in C#: use the .NET
WebDriverWaitAPI and itsTimeSpanexample, not Java constructors or method names.

Frequently Asked Questions
Does Selenium C# use a FluentWait class?
The documented .NET pattern configures WebDriverWait, which inherits from DefaultWait<IWebDriver>; do not transfer Java’s FluentWait syntax to C#.
Best Value
Can I use Selenium Expected Conditions in .NET Selenium 4?
Selenium’s documentation says built-in Expected Conditions are no longer supported in .NET. Use a predicate with Until or verify any separate library you choose.
