In this post, we look at adding theming capabilities to the ServiceStack Razor View engine. Source and live demo are included. This post is third in a series investigating ways to leverage ServiceStack in building a RESTful API and UI from a database. The main objective for this new theming capability is to allow easy development of new themes on top of the ServiceStack Razor view engine, with fallback capability to the default theme for views, content pages, master pages and layouts that don’t require specific theming.
