Recently, I used the WebView control in Xamarin Form a lot recently. WebView required you to set HeightRequest. If you did not set HeightRequest at all, it won't display at all. That is not a deal, when the WebView has fixed height. However, if you want the height of WebView based on its html content, that will be very hard. You need to write a custom renderer to do that. Xamarin forum has some examples for this purpose.
