#5 Page Icons for Favicon, Apple/Android

RazorBlade AddIcon to Html Headers

⚠️ WARNING: These examples only work in Dnn ☢️

2sxc 12 introduces the new PageService which also works in Oqtane 💧. We suggest you use that instead. 👉 See Razor Page Service
Note that to ensure this tutorial can run on all platforms, we've included some #if NETCOREAPP which changes what code runs on what platform.

Info about the Base Class

This tutorial inherits from the Custom.Hybrid.Razor14 base class.

This allows us to use Kit.Scrub to access IScrub without having to use GetService<>

This page sets various icon headers according to best practices. Look at the html-header in the output-source to see the effect.
The following links will set different icons depending on what you need.
