AutoMapper Version 9.0.0 - No ConfigureMap() Method on IMappingOperationOptions

Question

I'm upgrading a Visual Studio 2019 solution's projects from AutoMapper version 8.0.0 to version 9.0.0. There are a number of places in the code that are calling a ConfigureMap() method. Errors in the build output state:

IMappingOperationOptions<TSource, TDestination> does not contain a definition for ConfigureMap and no accessible extension method ConfigureMap...

Here are examples of what the current code looks like:

Mapper.Map(TSource, TDestination, opt => opt.ConfureMap());

Mapper.Map(TSource, TDestination, opt => opt.ConfigureMap().ForMember(dest => dest.someBool, m => m.MapFrom(src => src.someBoolVal));

I've looked at AutoMapper's documentation for upgrading from 8.0.0 to 9.0.0 and see no mention of the ConfigureMap() method being deprecated. However, it's not appearing when I search VS's Object Browser.

I would be most appreciative if anyone can share code for how to accomplish the same functionality in 9.0.0.

you are going to have to move away from inline mapping. there isnt even documentation for it in v9. – Mudfish

To whoever down-voted my question, wouldn't it have been more productive to provide an answer, or a helpful link? A down-vote means the person posing the question does not demonstrate any research effort, or the question is unclear or not useful. I stated part of the research effort I made (AutoMapper documentation, as well as many unmentioned sources), and I tried to be as clear as possible in stating my question and providing code examples. – Peplum

Answer 1

I had the same issue (IMappingOperationOptions not contain a definition for ConfigureMap) and I solved with a different approach.

//Step 1. Create a MapperConfiguration
var customMapConfig = new MapperConfiguration(cfg => {
    cfg.CreateMap<originClass, destClass>()
        .ForMember(dest => dest.FieldA, opt => opt.Ignore())
        .ForMember(dest => dest.FieldB, opt => opt.Ignore());
});

//Step 2. Create the custom Mapper
var customMapper = customMapConfig.CreateMapper();

//Step 3. Execute
customMapper.Map<originClass, destClass>(objOrigin, objDest);
