Visual Studio project to call Azure ML Endpoint, namespace how-to - visual-studio-code

Question

I have a Visual Studio WebForm C# project that loads in a browser. I also have a snippet of code from Azure ML to call my endpoint model. How should the *.aspx.cs file look? Thank you.

Here is how I plan to call it from the carprice.aspx file:
<asp:Label ID="lblResults" runat="server" Text="here is where results will go"></asp:Label>
Here is the Namespace template from Visual Studio project, the carprice.aspx.cs file:
namespace web13
{
public partial class carprice : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
}
}
And here is the snippet from Azure, a different kind of namespace syntax:
namespace CallRequestResponseService
{
class Program
{
static void Main(string[] args)
{
InvokeRequestResponseService().Wait();
}
static async Task InvokeRequestResponseService()
{
var handler = new HttpClientHandler()
{
ClientCertificateOptions = ClientCertificateOption.Manual,
ServerCertificateCustomValidationCallback =
(httpRequestMessage, cert, cetChain, policyErrors) => { return true; }
};
using (var client = new HttpClient(handler))
{
// Request data goes here
var scoreRequest = new
{
Inputs = new Dictionary<string, List<Dictionary<string, string>>>()
{
{
"input1",
new List<Dictionary<string, string>>()
{
new Dictionary<string, string>()
{
{
"price", "5800"
},
{
"year", "2013"......etc
The next day, I tried calling HTML label control from the Azure snippet of code, but I get an error, "the name lblResults2 does not exist in the current context." I've also tried changing the Azure snippet to Public classes. Here is another screen shot. thank you.

further days along, this is what gets Visual Studio to compile and load in browser. screen shot is:
