Show HN: Updating UI in WebView2 via an HTTP Request

Another user asked me how I was doing this in the (I guess now deleted) post about MS Teams using WebView2, so put this together.

We're building software for shops with poor internet connectivity, and a number of machines on the same LAN, so came up with this to enable an order kiosk (think McDonalds) to send the order to the til, and update the Til's UI, which then sends data back (if that makes sense).

Figured others may find it useful, all dotnet core etc.
