Problems Faced during Xamarin Prewier

There is a bug in Xamarin Prewier which results that it will not work as aspected during the android project.

The solution of this annoying bug is that you have to always connected to Mac.I know you may be wandering that what is the need of having Mac when you are just working on Android project.But sadly this is only solution.


Invalid XAML: The Android project needs to built before preview can be created
The XAML Previewer requires that the project be built before rendering a page. If the error below appears at the top of the preview pane, re-build the application and try again.
