Fix project that do request to search bing not work [C#] -- 2

Im making a simple project that do a search in bing.com using HttpWebRequest
The problem is that te html result not show the result of bing search but if I do the same search manually I got result.
If you have experience in webrequest or HttpWebRequest i think you can fix it fast.
I can send the project files if you send me a good proposal.

I think we must change the request method. I also tried with restSharp but not work.

thanks !
