Comparison of Object Mapper Libraries
For this evaluation, a C# .Net Core 5 console application was used using EntityFramework Core and SqlLite database. It is a simplified model of a layered architecture and available on GitHub.

🔴 [Mapster] A fast, fun and stimulating object to object Mapper! Mapster was designed to be efficient on both speed and memory. You could gain a 4x performance improvement whilst using only 1/3 of memory.

Is Automapper the most hated library?
Which is the main reason I don't use it anymore. I can still stand behind why it was created and what it was trying to solve. If you still want to use a mapper I would recommend Mapster as it supports source generation so you can see all code and it's references.
-
When using the DTO pattern and rolling your own mappers, is there a shorter way to write the mapping functions?
Gotta add a shoutout to Mapster which does pretty much the same thing also using source generation.

What C# tools would you like to use that don't exist today?
We use Mapster coupled with FastExpressionCompiler and have been very happy with it.

Unit Tests Done Right (Part 2)
I hope I managed to convince you and proved the value of unit tests for mappings, so let's move on to the next example. We're going to use AutoMapper, but from a testing standpoint, the choice of mapper makes no difference. For instance, we can replace AutoMapper with Mapster and it won't affect our tests in any way. Moreover, the existing tests will indicate whether our mapping refactoring was successful or not, which is one of the points of having unit tests 🙂
