103-103: Good addition of the named constant for DevTools protocol version.

This is a positive change that moves away from using the magic number directly in the method call. Having a named constant makes the code more maintainable and ensures that when the protocol version needs to be updated in the future, it can be done in a single location.

✅ Verification successful

Using the constant improves code maintainability.

Good improvement to use the newly defined constant instead of hardcoding the protocol version directly in the method call. This makes the code easier to maintain when Edge updates its DevTools protocol version.

For even better future-proofing, consider implementing a dynamic version detection mechanism. You could check if a more robust solution is possible by searching:

How to dynamically determine DevTools protocol version in Selenium C#

Dynamically Determining DevTools Protocol Version in Selenium C#

When working with Selenium C# and Chrome DevTools Protocol (CDP), it's important to align your DevTools session and code to the correct protocol version that matches your Chrome browser. Selenium 4's CDP integration is heavily version-specific, meaning that the API wrappers and commands are tied to specific Chrome/DevTools protocol versions[2][5][6][7].

Why Is This Needed?

• The DevTools (CDP) APIs in Selenium C# are organized into versioned namespaces such as OpenQA.Selenium.DevTools.V91 or OpenQA.Selenium.DevTools.V130, depending on Chrome's protocol version[5][6].
• Using the wrong version typically results in runtime errors or missing definitions for certain domains/methods[4][8].

Key Concepts

• DevToolsSession: Main entry point to interact with CDP in Selenium.
• Version-Specific Domains: You must reference and use domain classes (e.g., Network, Page, etc.) from the namespace matching your browser's CDP protocol version[6][5].
• Protocol Version Discovery: Selenium does not always automatically detect the right protocol version, especially in newer C# bindings[8].

Practical Steps

1. Detect the Chrome/DevTools Protocol Version

• The DevTools protocol version often closely tracks Chrome browser versions, but there isn't a one-to-one mapping. The official CDP version table is most accurate for mapping.
• In C#, Selenium does not always provide an automatic way to determine and load the correct CDP version for you. When the protocol version cannot be automatically detected, a warning or error such as:

"A WebSocket address for DevTools protocol has been detected, but the protocol version cannot be automatically detected. You must specify a protocol version."[8]

• Generally, you need to:
  1. Programmatically detect the browser version (e.g., via driver.Capabilities).
  2. Map it to the appropriate CDP version.
  3. Use the corresponding versioned namespace in your code.

2. Example: Using Versioned DevTools Domains in C#

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.DevTools;
using OpenQA.Selenium.DevTools.V130.Network; // Use the version matching your browser/protocol

var driver = new ChromeDriver();
DevToolsSession devToolsSession = ((ChromeDriver)driver).GetDevToolsSession();
var network = devToolsSession.GetVersionSpecificDomains<OpenQA.Selenium.DevTools.V130.DevToolsSessionDomains>().Network;

network.Enable(new EnableCommandSettings());
// Now you can subscribe to events, send commands, etc.

You must replace V130 with the actual namespace matching your Chrome's CDP version[6][5].

3. Automating the Version Mapping

There is no built-in Selenium API to dynamically resolve and generate the correct using directive at runtime, since these are compile-time dependencies. However, you can:

• Detect the browser version at runtime.
• Maintain a mapping (dictionary) in your code between Chrome versions and the corresponding DevTools protocol version.
• Use reflection (advanced) or factory pattern to instantiate the correct domain classes at runtime, if you really want to automate it. However, the most robust approach is to ensure your test environment uses a known version of Chrome and the matching Selenium DevTools package[6][5][10].

4. Example of Mapping Browser to CDP Version

1. Retrieve the browser version:

   var chromeVersion = ((ChromeDriver)driver).Capabilities.GetCapability("browserVersion").ToString();

2. Use a lookup table (manually maintained or generated from the CDP protocol mapping page) to find the corresponding DevTools version.

3. Reference the correct namespace in your code. You cannot dynamically reference namespaces at runtime in C# without advanced reflection or code generation.

5. Handling Protocol Version Errors

If you do not match the correct version, expect errors or warnings about unsupported protocol versions and missing features[8][10].

Summary Table

Task	Method/Approach
Determine Chrome Version	Use driver capabilities
Map to CDP Version	Use a lookup table (from official CDP docs)
Reference CDP Namespace in Code	Use correct using OpenQA.Selenium.DevTools.VXXX;
Dynamic Loading (advanced)	Reflection/factory pattern, but rarely needed in practice
Error if Version Mismatch	"Cannot be automatically detected. You must specify version."

Conclusion

There is currently no fully dynamic way to determine and load the correct DevTools protocol version in Selenium C#, because the necessary type definitions are determined at compile time[5][6][8]. The standard practice is:

• Manually match your Selenium DevTools package version (and corresponding namespace) to your browser's CDP version.
• Keep browser and driver versions synchronized in your CI/CD or test environment.
• Use runtime detection and factory patterns if you need to support multiple versions in one codebase, but this requires more sophisticated C# techniques.

For most projects, the best approach is to standardize on a tested Chrome + CDP + Selenium version combination and reference the correct DevTools namespace in your code[5][6].

Using Constant Is Ideal; Dynamic CDP Version Loading Isn’t Supported in C#

Great job replacing the hard-coded protocol version with the DevToolsProtocolVersion constant—this will save maintenance headaches whenever Edge’s CDP version is bumped.

Note: Selenium’s C# CDP bindings use compile-time namespaces (e.g. OpenQA.Selenium.DevTools.V130), and there is no built-in way to autodetect and reference the correct namespace at runtime. If you do need to support multiple CDP versions in one codebase, consider:

• Getting the browser version at runtime via ((ChromeDriver)driver).Capabilities.GetCapability("browserVersion").
• Maintaining a lookup table from browser versions to CDP namespace versions.
• Using a simple factory or reflection to instantiate the appropriate DevToolsSessionDomains.
• Locking your CI/CD Chrome + CDP + Selenium versions to a known combination to avoid version mismatches.
