Cannot resolve theme:LightTheme

Question

Hi, I'm new to Xamarin and hoped the Essentials UI kit might make life a bit easier.

I created a single page starter Xamarin.Forms project with Visual Studio 2019, updated the Xamarin.Forms to the latest version in NuGet. I then picked a few pages from the Essentials extension, allowed the code to update and then tried to compile. The compiler fails with the following message:

XFC0000 Cannot resolve type "themes:LightTheme". in App.xaml

As this is a completely blank project I don't think there should be any existing code it could be clashing with, is there an easy fix to ensure the code compiles?

Any help for a newbie much appreciated.

Providing your App.xaml source code will make providing assistance easier, even if it was generated by a tool and you didn't update it.
