Country Tag Helper–part 4

Now I want to see somewhere in order to prove it Ii s right. I choose https://appharbor.com/ because it is free – and can not beat free for free source.

I made github integration and modify the .csproj file accordingly to https://support.appharbor.com/discussions/problems/90387-is-net-core-supported-yet 

The result is at http://countrytaghelper.apphb.com/ 

Also,I have to modify the code source to get the ip of the user :

string GetUserIP(ViewContext vc)
        {
            StringValues headerFwd;
            if (ViewContext.HttpContext?.Request?.Headers?.TryGetValue("X-Forwarded-For",out headerFwd) ?? false)
            {
                string rawValues = headerFwd.ToString();
                if (!string.IsNullOrWhiteSpace(rawValues))
                {
                    return rawValues.Split(',')[0];
                }

            }
            return ViewContext.HttpContext?.Connection?.RemoteIpAddress?.ToString();

        }

where ViewContext is

 [ViewContext]
        public ViewContext ViewContext { get; set; }
