Archetype Mapper is an extension to Umbraco Mapper that helps you to map the content directly to your C# model, therefore you don’t need to de-serialise or parse JSON to retrieve data. Archetype mapper also supports nested Archetype properties.
Archetype Mapper like Umbraco Mapper uses conventions to map from IPublishedContent fields to view model fields; Archetype mapper extends it to allow you to map Archetype fields by convention too.
If preferred, you can also install it via Nuget:
PM> Install-Package ArchetypeMapper
