I am currently starting an Xamarin Application. Now i wonder if there is any form of designer for the UI, so I do not have to start the application over and over again to test the UI while designing?
Unfortunately there is no designer.
The closest thing will be the Xamarin Live Player which is currently in Preview.
Another alternative is the Xaml Previewer for Xamarin.Forms
There are two tools used as said by cheddy - Gorilla Player and Live XAML. I have tried the gorilla player but it doesnot work for dot Net standards. then I found Live XAML which is a great live development toolalong with the XAML previewer. So I personally prefer to use Live XAML.
All those xamarin live player, live previewer, inspector, gorilla player are useless the more your app grows. maybe for basic, small apps and if you dont use any DI or 3rd party tools like from telerik or syncfusion and you have to do a lot of set ups, face with connection lost problems etc etc. Only fully working extension is LiveXaml extension which is unfortunately not free.
Good luck finding one. None of these work.
