DOM shadow root elements finder using Selenium solution in .NET.

One of the important aspect of web components is encapsulation and Shadow DOM API is a key part of this, allowing hidden DOM trees to be attached to elements in the regular DOM tree. This shadow DOM tree starts with a shadow root, underneath which any elements can be attached, in the same way as the normal DOM. The solution combines the power of Document Query Selector API with Selenium to grab such shadow root DOM trees and interact with any elements encapsulated within it.

Selenium 4.1.x+ - Current supported package/solution version.
Selenium 4.0.x - Check support here.
Selenium 3 - Check support here.

The package is available and can be downloaded using nuget.org package manager.
