AutoMapper VS CH.CleanArchitecture

AutoMapper

The 13.0 Upgrade Guide page was created back in April, but there is no sign of the release yet.

The most well-know is probably AutoMapper, but it's not universally liked.

AutoMapper - well for automapping

When working with AutoMapper, we often bump into runtime errors due to invalid mapping configuration, such as this one:

What problems will resolve automapper?

If you are a fan of data mappers, you might want to enhance the implementation with additional extension methods. Here is an example for AutoMapper.

I'm wondering myself. Most mappers like https://automapper.org/ will make a best effort mapper automatically via introspection. If this is just a DSL/annotation suite that requires explicit, complete mapping implementations then this strikes me as a re-implementation of parts of kotlin in kotlin.

The IAggregateRoot interface is pretty specific to the overall architecture, as you may notice from the few domain-event-related functions in there. For more information regarding this, take a look at my earlier post Designing the domain model to support multiple persistence methods. Despite that, the point of this is to distinguish between data entities and domain entities so you should adjust this interface properly to your needs.

The repository for the source code of this solution can be found here. The solution includes an extremely basic domain model for an online shop application, as an example. The UI part for this is not included however. The order domain exists to simply showcase the different elements of the architecture.
