Here is some code,to request html-code from url.

var currentUrl = "https://www.google.com";
HttpClient client = new HttpClient();
System.Diagnostics.Process.Start(currentUrl); //here i open a browser with same URL, 
var response = await client.GetAsync(currentUrl);
string sourse = null;


if (response != null && response.StatusCode == HttpStatusCode.OK)

 sourse =await response.Content.ReadAsStringAsync(); // here i get the html-code

SO, the questions is: why html code that i get from program,and html code from real page in browser i have opened few secods before are different? It doesn't make sence.

Also, here is some proofs. First image - number of character in browser-html code

... and in program-html code

I gave the simplest evidence, to make the question more easier.
But if I dig deeper, the html code comes from nowhere. When I parse a specific page, and it should be 39 products, the program returns the html code, which only 6 products (which, incidentally, are not included in the 39 those that are actually on the page in the browser). So I asked the question so simply.
Really,i make a new project a minute ago with this code, and it work incorrect as I wrote above. to get the code that the program returns, I can look it up in the sourse variable or leave it in a file, and then compare. Like:

 FileStream fs = new FileStream("report.txt", FileMode.OpenOrCreate);
 StreamWriter SW = new StreamWriter(fs);
 SW.WriteLine(sourse);

  What makes you think it's invalid? How can you tell? And have you considered that your browser may be providing a lot more HTTP headers when it makes that GET request to google than your HttpClient is?

  HttpClient is not browser. Browser will download the page, render it and run scripts in it, HttpClient will not do it.

  @MisterCrabs You are looking at browser controls, like cefsharp.github.io, or .Net Framework's WebBrowser. No matter what you choose, you should check your goal. Why are you getting HTML code?
