Automapper says Mapper.Map is obsolete, global mappings?

Question

I had defined in my project a global Automapper configuration that would allow me to use Mapper.Map(sourceObject); in my code. (See my configu

This is how I've handled it.

Create maps in a Profile, taking care to use the Profile's CreateMap method rather than Mapper's static method of the same name:

internal class MappingProfile : Profile
{
    protected override void Configure()
    {
        CreateMap();
    }
}

Then, wherever dependencies are wired-up (ex: Global.asax or Startup), create a MapperConfiguration and then use it to create an IMapper.

var mapperConfiguration = new MapperConfiguration(cfg =>
    {
        cfg.AddProfile(new MappingProfile());
    });

Then, use the configuration to generate an IMapper:

var mapper = mapperConfiguration.CreateMapper();

Then, register that mapper with the dependency builder (I'm using Autofac here)

builder.RegisterInstance(mapper).As();

Now, wherever you need to map stuff, declare a dependency on IMapper:

internal class ProjectService : IProjectService {
    private readonly IMapper _mapper;
    public ProjectService(IMapper mapper) {
         _mapper = mapper;
    }
    public ProjectCreate Get(string key) {
        var project = GetProjectSomehow(key);
        return _mapper.Map(project);
    }
}
