Intro

Single file AutoMapper Extension.

Copy the MapperExtension.cs file to your project.

Usage

Create yourself MapperProvider

public static class MapperProvider
{
    public static IMapper Service { get; }

    static MapperProvider()
    {
        MapperConfiguration configuration = new(CreateMap);
#if DEBUG
        configuration.AssertConfigurationIsValid();
#endif
        Service = configuration.CreateMapper();
    }

    private static void CreateMap(IMapperConfigurationExpression cfg)
    {
        cfg.CreateMap<MyProperty, MyPropertyViewModel>().IgnoreAllMembersNull().IgnoreAllNotMappedAttribute().Forget();

        cfg.CreateMap<MyPropertyViewModel, MyProperty>().IgnoreAllMembersNull().IgnoreAllNotMappedAttribute().Forget();

        cfg.CreateMap<PointAngle, PointProperty>().ForAllMembersCustom((src, dest) =>
        {
            // My mapper func here.
        });

        cfg.CreateMap<MyPropertyViewModel, MyPropertyViewModel>().IgnoreAllMembersNull().ForAllMembersCloneable().Forget();
    }

    public static TDestination MapDefault<TSource, TDestination>(TSource source, TDestination destination)

        });
    }

        });
    }

            return mapper.Map<TSource, TDestination>(source);
        }
        if (Service?.ConfigurationProvider.FindTypeMapFor<TSource, TDestination>() != null)
        {
