Description

Adds the missing C# test for the unhandledPromptBehavior option and points the docs at it, replacing the placeholder badge in the CSharp tab.

Motivation and Context

The CSharp tab for unhandledPromptBehavior in options.en.md showed a placeholder badge instead of a code example, unlike Java, Python, and Ruby. This combines the code from #2611 and the doc update from #2612 (both by @kimtg) into one PR, fixing the line-range format in the doc reference along the way.

Types of changes

• Change to the site (I have double-checked the Netlify deployment, and my changes look good)
• Code example added (and I also added the example to all translated languages)
• Improved translation
• Added new translation (and I also added a notice to each document missing translation)

Checklist

• I have read the contributing document.
• I have used hugo to render the site/docs locally and I am sure it works.

🐞 Bugs (5) 📘 Rule violations (1) 📜 Skill insights (0)

Context used

✅ Compliance rules (platform): 10 rules

1. Edge docs #L30-L31 stale 📘 Rule violation ≡ Correctness

Description

New lines added to EdgeTest.cs shifted line numbers, but the Edge browser docs still reference the
old gh-codeblock anchors (e.g., #L30-L31), causing the rendered C# snippet to show unrelated
cleanup code. This violates the requirement to update doc line ranges whenever examples/ files
change.

Code

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[R21-33]

+            driver.Quit();
+
            if (_logLocation != null && File.Exists(_logLocation))
            {
-                File.Delete(_logLocation);
+                try
+                {
+                    File.Delete(_logLocation);
+                }
+                catch (IOException)
+                {
+                    // On Windows, the driver service can still hold the log file open for a
+                    // moment after driver.Quit(), so tolerate the race instead of failing cleanup.
+                }

Evidence

The docs still embed EdgeTest.cs#L30-L31 for the "Starting an Edge session" snippet, but
EdgeTest.cs line 30 is now catch (IOException) (cleanup code), demonstrating the line anchors
are no longer aligned after the changes in Cleanup().

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The Edge docs reference `EdgeTest.cs` using `gh-codeblock` line anchors that were correct before this PR, but are now stale due to added lines in `Cleanup()`. As a result, the docs render the wrong C# snippet.

## Issue Context
`examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs` was modified (additional lines in `Cleanup()`), which shifts subsequent line numbers. Multiple docs pages still point to the old `#L..` anchors for this file.

2. Service dispose not guaranteed 🐞 Bug ☼ Reliability ⭐ New

Description

In EdgeTest log tests, EdgeDriverService.Dispose() is only called on the success path; if EdgeDriver
construction or driver.Quit() throws, the service is never disposed and can leave the driver
process/log file handle open. This can cause follow-on test flakiness and persistent log file locks
in the suite.

Code

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[R108-109]

+            service.Dispose(); // Close the Service log file before reading
+            var lines = ReadLogLines(GetLogLocation());

Evidence

The updated tests explicitly rely on service.Dispose() to release the log file handle, but there
is no try/finally/using ensuring it runs if earlier steps throw. TestCleanup only quits the
driver field and does not dispose these locally-created service instances.

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[98-111]
examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[113-129]
examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[131-150]
examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[152-169]
examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[19-36]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`EdgeDriverService` is disposed only on the happy path in multiple tests. If `new EdgeDriver(service, options)` or `driver.Quit()` throws, `service.Dispose()` is skipped and may leak resources (including log file handles), leading to downstream flakiness.

### Issue Context
These tests intentionally manage the service log file lifecycle (`service.Dispose(); // Close the Service log file before reading`) and then immediately read the log file. This makes guaranteed disposal particularly important.

### Fix Focus Areas
- examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[98-169]

### Suggested fix
Wrap each test’s driver/service lifecycle with `try/finally` (or `using` + `try/finally`) so `service.Dispose()` always runs, even if driver construction or `Quit()` fails. For example:

```csharp
var service = EdgeDriverService.CreateDefaultService();
try
{
   service.LogPath = GetLogLocation();
   driver = new EdgeDriver(service, options);
   driver.Quit();
}
finally
{
   // Ensure service is released even if constructor/Quit throws
   service.Dispose();
}

var lines = ReadLogLines(GetLogLocation());
```

(Apply similarly in `LogsLevel`, `ConfigureDriverLogs`, and `DisableBuildCheck`.)

3. Overbroad IOException retries ✓ Resolved 🐞 Bug ☼ Reliability

Description

EdgeTest.ReadLogLines retries any IOException (including permanent failures like missing file/path),
so real errors can be delayed by ~9.5s (19×500ms) before surfacing, slowing CI failures and
obscuring root cause.

Code

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[R169-181]

+            const int maxAttempts = 20;
+            for (var attempt = 1; attempt <= maxAttempts; attempt++)
+            {
+                try
+                {
+                    return File.ReadAllLines(path);
+                }
+                catch (IOException) when (attempt < maxAttempts)
+                {
+                    // On Windows, the driver service can still hold the log file open for
+                    // several seconds after driver.Quit(), so retry until the handle is released.
+                    Thread.Sleep(500);
+                }

Evidence

The new helper retries on any IOException solely based on attempt count, sleeping 500ms each time,
which will also apply to non-transient IO errors and delay failure.

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[167-185]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`ReadLogLines` currently retries on *all* `IOException`s, not just transient file-sharing/lock violations. This means permanent problems (e.g., log path wrong, file missing) can incur ~10 seconds of sleeping before the test fails, making failures slower and harder to diagnose.

### Issue Context
The retry was introduced to tolerate Windows file-handle release races after `driver.Quit()`. That’s a specific subset of `IOException`s (sharing/lock violations), so the retry should be narrowed to those conditions.

### Fix Focus Areas
- examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[169-181]

### Suggested fix approach
- Narrow the retry condition to only sharing/lock violations (e.g., check `ex.HResult` for Windows sharing/lock violation codes), and/or
- Bail out immediately if `!File.Exists(path)` to avoid retrying missing-file failures.
- Optionally include the last exception in a rethrow with additional context after attempts are exhausted.

4. Null-unsafe driver quit ✓ Resolved 🐞 Bug ☼ Reliability

Description

EdgeTest.Cleanup() now calls driver.Quit() unconditionally and before log cleanup; if driver was
never assigned (e.g., driver creation fails), Cleanup throws NullReferenceException, masking the
original failure and skipping log deletion. This makes the test suite less reliable and harder to
diagnose when setup fails.

Code

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[R21-22]

+            driver.Quit();
+

Evidence

The driver field is declared without initialization and is dereferenced unconditionally in
Cleanup(); similar test infrastructure uses driver?.Quit() to avoid cleanup-time null dereferences
when driver startup fails.

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[15-35]
examples/dotnet/SeleniumDocs/BaseTest.cs[25-34]
examples/dotnet/SeleniumDocs/Browsers/ChromeTest.cs[22-30]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`EdgeTest.Cleanup()` calls `driver.Quit()` unconditionally and *before* the log deletion block. If `driver` was never created/assigned (e.g., driver startup fails), Cleanup will throw `NullReferenceException`, masking the real test failure and preventing log-file cleanup.

### Issue Context
Other dotnet examples in this repo use null-safe cleanup patterns (e.g., `driver?.Quit()`), indicating the test harness expects driver creation to sometimes fail or be skipped.

### Fix Focus Areas
- examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[21-34]

### Suggested fix
- Change to `driver?.Quit()` (or `if (driver != null) driver.Quit();`).
- Wrap quit/delete in `try/finally` so log deletion still runs even if `Quit()` throws.
- Optionally catch and ignore/log `WebDriverException` from `Quit()` to avoid cleanup masking the real failure.

5. Network-dependent CI test 🐞 Bug ☼ Reliability

Description

SetUnhandledPromptBehavior navigates to https://selenium.dev, adding an unnecessary external network
dependency to the dotnet examples test suite. This test will fail whenever selenium.dev (or outbound
HTTPS/DNS) is unavailable, even though setting UnhandledPromptBehavior does not require network
access.

Code

examples/dotnet/SeleniumDocs/Drivers/OptionsTest.cs[R61-65]

+            IWebDriver driver = new ChromeDriver(chromeOptions);
+            try
+            {
+                driver.Navigate().GoToUrl("https://selenium.dev");
+            }

Evidence

The new test explicitly navigates to an external site, and the repo’s workflow runs these tests on
PRs affecting the dotnet examples, so the external dependency is exercised in CI.

examples/dotnet/SeleniumDocs/Drivers/OptionsTest.cs[56-70]
.github/workflows/dotnet-examples.yml[1-99]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
`SetUnhandledPromptBehavior()` demonstrates setting an option, but it performs a real navigation to `https://selenium.dev`, which adds an avoidable external dependency (DNS + outbound HTTPS + site availability) to CI.

## Issue Context
The dotnet examples are executed in CI via `dotnet test`, so this test increases flakiness for reasons unrelated to the option being demonstrated.

## Fix Focus Areas
- examples/dotnet/SeleniumDocs/Drivers/OptionsTest.cs[56-70]
- .github/workflows/dotnet-examples.yml[1-99]

## Suggested fix
Replace the external navigation with a non-network URL, e.g.:
- `driver.Navigate().GoToUrl("about:blank");` or
- `driver.Navigate().GoToUrl("data:text/html,<html><title>test</title></html>");`

This keeps the example deterministic while still showing the option usage.

6. Eager log reads 🐞 Bug ➹ Performance

Description

EdgeTest now uses File.ReadAllLines() to read driver logs even though each test only needs to find a
single matching line, forcing unnecessary full-file I/O and memory usage (especially with verbose
logging enabled). This can slow the test suite and scales poorly if the driver emits large logs.

Code

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[146]

+            var lines = File.ReadAllLines(GetLogLocation());

Evidence

The updated Edge tests read the full log into an array before searching for a single match, while
comparable Chrome tests stream the log with ReadLines and perform the same FirstOrDefault check
without loading the entire file.

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[96-168]
examples/dotnet/SeleniumDocs/Browsers/ChromeTest.cs[102-162]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
`EdgeTest` was changed from `File.ReadLines(...)` to `File.ReadAllLines(...)` in multiple log assertions. These tests only need to locate one matching line (via `FirstOrDefault`), so reading the entire log into memory is unnecessary work.

## Issue Context
This is most relevant in `ConfigureDriverLogs`, where verbose logging is enabled and logs can be larger.

## Fix Focus Areas
- examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[103-168]

## Suggested change
Replace `File.ReadAllLines(GetLogLocation())` with `File.ReadLines(GetLogLocation())` (or inline the search: `Assert.IsNotNull(File.ReadLines(...).FirstOrDefault(...))`) in:
- `LogsToFile`
- `LogsLevel`
- `ConfigureDriverLogs`
- `DisableBuildCheck`

7. Unreachable retry fallback ✓ Resolved 🐞 Bug ⚙ Maintainability

Description

ReadLogLines() always returns from inside the loop on success or throws on the final attempt, so the
trailing return File.ReadAllLines(path); after the loop is dead code and makes the retry logic
misleading to maintainers.

Code

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[R169-185]

+            const int maxAttempts = 10;
+            for (var attempt = 1; attempt <= maxAttempts; attempt++)
+            {
+                try
+                {
+                    return File.ReadAllLines(path);
+                }
+                catch (IOException) when (attempt < maxAttempts)
+                {
+                    // On Windows, the driver service can still hold the log file open for a
+                    // moment after driver.Quit(), so retry until the handle is released.
+                    Thread.Sleep(200);
+                }
+            }
+
+            return File.ReadAllLines(path);
+        }

Evidence

In the new ReadLogLines helper, the try block returns immediately on any successful read. If
File.ReadAllLines keeps throwing, on the last iteration (attempt == maxAttempts) the `catch
(IOException) when (attempt < maxAttempts)` does not apply, so the exception propagates and the
function never reaches the final return statement.

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[167-185]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`ReadLogLines` contains a `return File.ReadAllLines(path);` after the retry loop that is unreachable: successful reads return inside the loop, and an `IOException` on the final attempt is not caught due to the catch filter and will throw.

### Issue Context
This is a maintainability/readability issue introduced with the new retry helper.

### Fix Focus Areas
- examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[167-185]

### Suggested fix
Refactor to make the final attempt explicit, e.g.:
- Run `maxAttempts - 1` retries inside the loop and then do one final `File.ReadAllLines(path)` outside the loop, or
- Keep the loop but remove the trailing return and let the final attempt throw naturally, or
- Use a single return after the loop with a `break` on success (no early returns) so control flow is obvious.

8. Silent log delete failure 🐞 Bug ◔ Observability

Description

Cleanup swallows IOException from File.Delete without retry or diagnostics, so persistent failures
to delete the log file can go unnoticed and leave stale temp logs behind. This reduces observability
when cleanup issues occur on Windows file-lock races beyond the expected transient case.

Code

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[R25-33]

+                try
+                {
+                    File.Delete(_logLocation);
+                }
+                catch (IOException)
+                {
+                    // On Windows, the driver service can still hold the log file open for a
+                    // moment after driver.Quit(), so tolerate the race instead of failing cleanup.
+                }

Evidence

The PR introduces an empty catch (IOException) around deleting a temp log file, which
intentionally ignores deletion failures and provides no diagnostics if it keeps failing.

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[162-170]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`Cleanup()` catches `IOException` from `File.Delete(_logLocation)` and silently ignores it. While this is intended to tolerate a transient Windows race, it provides no signal if deletion fails persistently.

### Issue Context
The log path is a temp file, so persistent inability to delete can leave stale temp logs and make cleanup problems hard to spot.

### Fix Focus Areas
- examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[25-33]

### Suggested fix
- Add a short bounded retry (e.g., 2–3 attempts with a small delay) before giving up.
- If still failing, emit a diagnostic message (test output/log) including the path and exception, or rethrow only after retries depending on desired strictness.

+                }

Evidence

The docs still embed EdgeTest.cs#L30-L31 for the "Starting an Edge session" snippet, but
EdgeTest.cs line 30 is now catch (IOException) (cleanup code), demonstrating the line anchors
are no longer aligned after the changes in Cleanup().

## Issue description
The Edge docs reference `EdgeTest.cs` using `gh-codeblock` line anchors that were correct before this PR, but are now stale due to added lines in `Cleanup()`. As a result, the docs render the wrong C# snippet.

## Issue Context
`examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs` was modified (additional lines in `Cleanup()`), which shifts subsequent line numbers. Multiple docs pages still point to the old `#L..` anchors for this file.

2. Null-unsafe driver quit ✓ Resolved 🐞 Bug ☼ Reliability

Description

EdgeTest.Cleanup() now calls driver.Quit() unconditionally and before log cleanup; if driver was
never assigned (e.g., driver creation fails), Cleanup throws NullReferenceException, masking the
original failure and skipping log deletion. This makes the test suite less reliable and harder to
diagnose when setup fails.

Code

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[R21-22]

+            driver.Quit();
+

Evidence

The driver field is declared without initialization and is dereferenced unconditionally in
Cleanup(); similar test infrastructure uses driver?.Quit() to avoid cleanup-time null dereferences
when driver startup fails.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`EdgeTest.Cleanup()` calls `driver.Quit()` unconditionally and *before* the log deletion block. If `driver` was never created/assigned (e.g., driver startup fails), Cleanup will throw `NullReferenceException`, masking the real test failure and preventing log-file cleanup.

### Issue Context
Other dotnet examples in this repo use null-safe cleanup patterns (e.g., `driver?.Quit()`), indicating the test harness expects driver creation to sometimes fail or be skipped.

### Fix Focus Areas
- examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[21-34]

### Suggested fix
- Change to `driver?.Quit()` (or `if (driver != null) driver.Quit();`).
- Wrap quit/delete in `try/finally` so log deletion still runs even if `Quit()` throws.
- Optionally catch and ignore/log `WebDriverException` from `Quit()` to avoid cleanup masking the real failure.

3. Silent log delete failure 🐞 Bug ◔ Observability

Description

Cleanup swallows IOException from File.Delete without retry or diagnostics, so persistent failures
to delete the log file can go unnoticed and leave stale temp logs behind. This reduces observability
when cleanup issues occur on Windows file-lock races beyond the expected transient case.

Code

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[R25-33]

+                try
+                {
+                    File.Delete(_logLocation);
+                }
+                catch (IOException)
+                {
+                    // On Windows, the driver service can still hold the log file open for a
+                    // moment after driver.Quit(), so tolerate the race instead of failing cleanup.
+                }

Evidence

The PR introduces an empty catch (IOException) around deleting a temp log file, which
intentionally ignores deletion failures and provides no diagnostics if it keeps failing.

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[162-170]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`Cleanup()` catches `IOException` from `File.Delete(_logLocation)` and silently ignores it. While this is intended to tolerate a transient Windows race, it provides no signal if deletion fails persistently.

### Issue Context
The log path is a temp file, so persistent inability to delete can leave stale temp logs and make cleanup problems hard to spot.

### Fix Focus Areas
- examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[25-33]

### Suggested fix
- Add a short bounded retry (e.g., 2–3 attempts with a small delay) before giving up.
- If still failing, emit a diagnostic message (test output/log) including the path and exception, or rethrow only after retries depending on desired strictness.

1. Unreachable retry fallback ✓ Resolved 🐞 Bug ⚙ Maintainability

Description

ReadLogLines() always returns from inside the loop on success or throws on the final attempt, so the
trailing return File.ReadAllLines(path); after the loop is dead code and makes the retry logic
misleading to maintainers.

Code

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[R169-185]

+            const int maxAttempts = 10;
+            for (var attempt = 1; attempt <= maxAttempts; attempt++)
+            {
+                try
+                {
+                    return File.ReadAllLines(path);
+                }
+                catch (IOException) when (attempt < maxAttempts)
+                {
+                    // On Windows, the driver service can still hold the log file open for a
+                    // moment after driver.Quit(), so retry until the handle is released.
+                    Thread.Sleep(200);
+                }
+            }
+
+            return File.ReadAllLines(path);
+        }

Evidence

In the new ReadLogLines helper, the try block returns immediately on any successful read. If
File.ReadAllLines keeps throwing, on the last iteration (attempt == maxAttempts) the `catch
(IOException) when (attempt < maxAttempts)` does not apply, so the exception propagates and the
function never reaches the final return statement.

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[167-185]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`ReadLogLines` contains a `return File.ReadAllLines(path);` after the retry loop that is unreachable: successful reads return inside the loop, and an `IOException` on the final attempt is not caught due to the catch filter and will throw.

### Issue Context
This is a maintainability/readability issue introduced with the new retry helper.

### Fix Focus Areas
- examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[167-185]

### Suggested fix
Refactor to make the final attempt explicit, e.g.:
- Run `maxAttempts - 1` retries inside the loop and then do one final `File.ReadAllLines(path)` outside the loop, or
- Keep the loop but remove the trailing return and let the final attempt throw naturally, or
- Use a single return after the loop with a `break` on success (no early returns) so control flow is obvious.

1. Overbroad IOException retries ✓ Resolved 🐞 Bug ☼ Reliability

Description

EdgeTest.ReadLogLines retries any IOException (including permanent failures like missing file/path),
so real errors can be delayed by ~9.5s (19×500ms) before surfacing, slowing CI failures and
obscuring root cause.

Code

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[R169-181]

+            const int maxAttempts = 20;
+            for (var attempt = 1; attempt <= maxAttempts; attempt++)
+            {
+                try
+                {
+                    return File.ReadAllLines(path);
+                }
+                catch (IOException) when (attempt < maxAttempts)
+                {
+                    // On Windows, the driver service can still hold the log file open for
+                    // several seconds after driver.Quit(), so retry until the handle is released.
+                    Thread.Sleep(500);
+                }

Evidence

The new helper retries on any IOException solely based on attempt count, sleeping 500ms each time,
which will also apply to non-transient IO errors and delay failure.

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[167-185]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

### Issue description
`ReadLogLines` currently retries on *all* `IOException`s, not just transient file-sharing/lock violations. This means permanent problems (e.g., log path wrong, file missing) can incur ~10 seconds of sleeping before the test fails, making failures slower and harder to diagnose.

### Issue Context
The retry was introduced to tolerate Windows file-handle release races after `driver.Quit()`. That’s a specific subset of `IOException`s (sharing/lock violations), so the retry should be narrowed to those conditions.

### Fix Focus Areas
- examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[169-181]

### Suggested fix approach
- Narrow the retry condition to only sharing/lock violations (e.g., check `ex.HResult` for Windows sharing/lock violation codes), and/or
- Bail out immediately if `!File.Exists(path)` to avoid retrying missing-file failures.
- Optionally include the last exception in a rethrow with additional context after attempts are exhausted.

1. Eager log reads 🐞 Bug ➹ Performance

Description

EdgeTest now uses File.ReadAllLines() to read driver logs even though each test only needs to find a
single matching line, forcing unnecessary full-file I/O and memory usage (especially with verbose
logging enabled). This can slow the test suite and scales poorly if the driver emits large logs.

Code

examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[146]

+            var lines = File.ReadAllLines(GetLogLocation());

Evidence

The updated Edge tests read the full log into an array before searching for a single match, while
comparable Chrome tests stream the log with ReadLines and perform the same FirstOrDefault check
without loading the entire file.

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
`EdgeTest` was changed from `File.ReadLines(...)` to `File.ReadAllLines(...)` in multiple log assertions. These tests only need to locate one matching line (via `FirstOrDefault`), so reading the entire log into memory is unnecessary work.

## Issue Context
This is most relevant in `ConfigureDriverLogs`, where verbose logging is enabled and logs can be larger.

## Fix Focus Areas
- examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[103-168]

## Suggested change

1. Service dispose not guaranteed 🐞 Bug ☼ Reliability

In EdgeTest log tests, EdgeDriverService.Dispose() is only called on the success path; if EdgeDriver
construction or driver.Quit() throws, the service is never disposed and can leave the driver
process/log file handle open. This can cause follow-on test flakiness and persistent log file locks
in the suite.

Agent Prompt

### Issue description
`EdgeDriverService` is disposed only on the happy path in multiple tests. If `new EdgeDriver(service, options)` or `driver.Quit()` throws, `service.Dispose()` is skipped and may leak resources (including log file handles), leading to downstream flakiness.

### Issue Context
These tests intentionally manage the service log file lifecycle (`service.Dispose(); // Close the Service log file before reading`) and then immediately read the log file. This makes guaranteed disposal particularly important.

### Fix Focus Areas
- examples/dotnet/SeleniumDocs/Browsers/EdgeTest.cs[98-169]

### Suggested fix
Wrap each test’s driver/service lifecycle with `try/finally` (or `using` + `try/finally`) so `service.Dispose()` always runs, even if driver construction or `Quit()` fails. For example:

```csharp
var service = EdgeDriverService.CreateDefaultService();
try
{
    service.LogPath = GetLogLocation();
    driver = new EdgeDriver(service, options);
    driver.Quit();
}
finally
{
    // Ensure service is released even if constructor/Quit throws
    service.Dispose();
}

var lines = ReadLogLines(GetLogLocation());
```

(Apply similarly in `LogsLevel`, `ConfigureDriverLogs`, and `DisableBuildCheck`.)
