While Microsoft’s new Edge browser has a cast feature, this only supports Micacast and other video casting technologies. However, simply enabling a few flags will get you the full Chromecast experience.
To enable the feature:
Open your Chrome web browser and go to download the Chromecast DMG by clicking the blue Download button and install the Chromecast app for Mac. Make sure to agree to the license terms (after reading them) and click the ACCEPT button.

In the latest Edge Preview:
Enter edge://flags in the address bar.
Search for #load-media-router-component-extension and enable it.
Search for #views-cast-dialog and enable it.
Restart the browser.
You should now be able to cast YouTube video by pressing the Cast button in the video, or other video by using the Cast Menu under More Tools
This feature by itself may be worth switching rendering engines. Hopefully, it will make it through to the final version of the browser.
