Helloooo umbraco

Is there any way to register additional maps within umbraco, currently im struggling to get my mappers to work, first i initialize them on application starting.

    protected override void OnApplicationStarting(object sender, EventArgs e)
    {

        base.OnApplicationStarting(sender, e);
        GlobalConfiguration.Configure(WebApiConfig.Register);

        AutoMapperWebConfiguration.Configure();


    }
    public static class AutoMapperWebConfiguration
    {
        public static void Configure()
        {
            Mapper.Initialize(cfg =>
            {
                cfg.AddProfile(new UserProfile());
            });
        }
    }

    public class UserProfile : Profile
    {
        protected override void Configure()
        {
            Mapper.CreateMap<Case, CaseDTO>();
        }
    }

Any Ideas why this is failing to register i had the idea umbraco maybe was overwriting my maps.

Thanks in advance :)
