DotNetBrowser does not interact with existing Chrome or Chromium installations - it brings its own Chromium-based engine. All required Chromium binaries and dependencies are deployed with the library. You don’t need to install Google Chrome, Chromium or Visual C++ Redistributable to work with DotNetBrowser.
Everything you see on the web page when you load it is rendered by the Chromium engine. DotNetBrowser just displays web page parts rendered by the Chromium engine. Chromium loads and renders web pages in separate native processes (Multi-Process Architecture). The web page looks exactly as in Google Chrome.
Since all Chromium functionality runs in separate native processes, the Chromium engine doesn’t use the memory of your .NET application.
