   public static class HttpContext
    {
        private static IHttpContextAccessor _accessor;

        public static Microsoft.AspNetCore.Http.HttpContext Current => _accessor.HttpContext;

        internal static void Configure(IHttpContextAccessor accessor)
        {
            _accessor = accessor;
        }
    }

    public static class StaticHttpContextExtensions
    {
        public static void AddCustomHttpContextAccessor(this IServiceCollection services)
        {
            services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
        }

        public static IApplicationBuilder UseStaticHttpContext(this IApplicationBuilder app)
        {
            var httpContextAccessor = app.ApplicationServices.GetRequiredService<IHttpContextAccessor>();
            HttpContext.Configure(httpContextAccessor);
            return app;
        }
    }
