Updating resources with PUT and AutoMapper

This recipe will demonstrate how to update an existing resource using PUT requests. Proper handling of resource updates is crucial for maintaining data integrity. For this task, you will learn how to use AutoMapper, a popular object-to-object mapping library. AutoMapper facilitates the mapping between Data Transfer Objects (DTOs) and entity models. AutoMapper also helps us reduce the boilerplate code needed for manual property mapping.

Getting ready

The repository is available here: https://github.com/PacktPublishing/ASP.NET-9-Web-API-Cookbook/tree/main/end/chapter02/AutoMapper. This starter project is different from the one we left off with, so it is crucial that you clone it if you want to follow along. The starter project includes an AdditionalContactInfo model for storing secondary contact details, which we’ll be mapping alongside our main EventRegistration model.
