possible with reflection. but I do not recommend. you want something that will check that the types all align - and for these types of mappings between layers I would expect that you will eventually need to transform some of the properties as well - while this will provide you no compile-time warnings and instead fail at runtime

I guess redundancy is in place to provide stable API separated from business logic. I think the best solution for this kind of problem is implementing plugin for build system or IDE, that would generate mappings automatically. This is requires a little additional work and won't pay off in small project. So if it's small project, I recommend implementing mapping manually. Reflection should be avoided due to various reasons. I understand you're a beginner since you posted on getting-started, so I recommend manual approach. One you feel comfortable enough I recommend looking into compiler plugins and code generation. May the force be with you!
