🔍 Flattening Explained
AutoMapper automatically flattens nested properties:
// Source object structure
Product {
Category {
Name = "Electronics"
Description = "Electronic devices"
}
}
// Destination DTO (flattened)
ProductDTO {
CategoryName = "Electronics" // Automatically mapped from Category.Name
CategoryDescription = "Electronic devices" // From Category.Description
}How it works: AutoMapper looks for properties that match the pattern NestedObjectProperty and automatically maps from NestedObject.Property.
