KutCode.AutoMapper.Extensions

.NET library that allows you:

• Configure Mappings in the type definition
• Use inheritance of interfaces for "default" mappings, without complex rules

📜 Installation

KutCode.AutoMapper.Extensions is designed with net7.0 and higher.

Install KutCode.AutoMapper.Extensions using NuGet Package Manager:

Install-Package KutCode.AutoMapper.Extensions

Or via the .NET CLI:

dotnet add package KutCode.AutoMapper.Extensions

All versions can be found here.

🚀 Quick Start

Basic example

Let's declare two types:

public class SomeEntity
{
    public string Value { get;set; }
}

public class SomeDto : IMapWith<SomeEntity> // <-- just inherit it
{
    public string Value { get;set; }
}

Use DI to configure AutoMapper:

global using AutoMapper;

WebApplicationBuilder builder = WebApplication.CreateBuilder(args);
// just call this to scan All assemblies
builder.Services.AddAllMappings();
// or select assemblies manually
builder.Services.AddMappings(typeof(Program).Assembly, typeof(Domain).Assembly);

So, that's all, now you can map with AutoMapper's IMapper as usual:

SomeDto dto = mapper.Map<SomeDto>(entity);

---

IMapFrom<T> and IMapTo<T>

⚠️ Whereas, you can also use those interfaces, which just calls CreateMap() if not overrided:

• IMapFrom<T> create map from T to implementing class
• IMapTo<T> create map from implementing class to T

---

Override default mapping

If you just inherite interface IMapWith<T> - that will created .ReverseMap() for two types.
So, you can override default mapping, and set your own behaviour:

public class SomeDto : IMapWith<SomeEntity>
{
    public string Value { get;set; }
    // override Map method
    public void Map(MapProfileDecorator<SomeEntity> decorator)
    {
        decorator.Profile.CreateMap<DataDto, DataEntity>()
            .ForMember(m => m.Value, opt 
                => opt.MapFrom(f => "SomeOverride")
            );
    }
}

---

Use multiple interfaces

public class SomeDto : IMapWith<SomeEntity>,
    IMapTo<AnotherOne>, IMapFrom<AndAnotherOne>
{
    public string Value { get;set; }
    
    // also overrides available for all intrfaces
}

---

✨ Conclusion

• Use IMapWith<T> for reverse mapping
• Use IMapFrom<T> to map from T to an implementing type
• Use IMapTo<T> to map from an implementing type to T

All of these interfaces allow you to override the Map(MapProfileDecorator<T>) method to customize the mapping.
