What are the different alternative frameworks available for object to object mapping in .NET apart from AutoMapper
Currently we're planning to use AutoMapper, but before finalizing this framework, we want to understand any other frameworks are out there.

1. If you use the convention-based mapping and a property is later renamed that becomes a runtime error and a common source of annoying bugs. 2. If you don't use convention-based mapping (ie you explicitly map each property) then you are just using automapper to do your projection, which is unnecessary complexity.
Inside this article, it discusses performance and it indicates that Automapper is 7 times slower than manual mapping. This test was done on 100,000 records and I must say I was shocked.
AutoMapper is used whenever there are many data properties for objects, and we need to map them between the object of source class to the object of destination class, Along with the knowledge of data structure and algorithms, a developer is required to have excellent development skills as well.
When you call CreateMap, AutoMapper uses optimizers to build the code for getting/setting values on source/destination types. Currently, it uses a combination of Reflection.
