What is AutoMapper used for?
AutoMapper in C# is a library used to map data from one object to another. It acts as a mapper between two objects and transforms one object type into another. It converts the input object of one type to the output object of another type until the latter type follows or maintains the conventions of AutoMapper.
Is AutoMapper a good idea?
AutoMapper is probably good for really small, short-lived projects or proof of concepts, but when you start to care about your code quality, you should definitely rethink all pros and cons regarding using AutoMapper.
Why you should not use AutoMapper?
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.
Is AutoMapper faster than manual mapping?
Inside this article, it discusses performance and it indicates that Automapper is 7 times slower than manual mapping.
What is AutoMapper in Entity Framework?
AutoMapper is an object-object mapper that allows you to solve the problem of manually mapping each property of a class with the same properties of another class. Before AutoMapper was introduced if we wanted to assign one object property to another object property then we were following a long procedure.
Does AutoMapper affect performance?
AutoMapper may result in performance costs both at startup (when mapping configurations are set up) and during processing (when actually mapping happens), and these costs might not be negligible for larger projects.
Is AutoMapper fast?
Automapper is slower when mapping a single object and collections but there is one exception. Automapper is considerably faster when mapping a List of objects on . NET Core (It’s still slower on full . NET Framework).

What is AutoMapper in MVC?

When these collections map from the ViewModel to the Model, rather than map properties, a new instance of a UserPreference object is created from the ViewModel, rather than update the existing object with the ViewModel properties. And automapper configuration: Mapper.
What is automapper in MVC?
In this article, I will try to cover a new concept in MVC: AutoMapper. AutoMapper is used to reduce the complexity we find when binding the model and communicating with entities. When we code for a realistic actual environment, we encounter many challenges to refractor our code for a better understanding and to easily identify the bugs.
Where can I get the automapper?
You can get the AutoMapper from the following website: AutoMapper. You can also see the samples and documentations. Now we will see where AutoMapper fits in our problem.
How do I map between two classes in automapper?
Well, AutoMapper provides a CreateMap method that provides mapping between two classes. So, the entire code can be replaced by the following single line: Where User is a DBContext class type and UserDto is our DTO class to map.
What is a profile in automapper?
