Operation is not supported on this platform. when using HttpClient.send on ios and android

Description

Why I try to call a service from ios or android I get a System.PlatformNotSupportedException. The code works perfectly in windows. even if I try to hit something like http://goole.ca I get the same error.

Steps to Reproduce

A added the following code to your default sample and get the error:

public partial class App : Application
{
	public App()
	{
		InitializeComponent();

		MainPage = new AppShell();

		try
		{
            HttpClient client = new HttpClient();
            HttpResponseMessage response = client.Send(new HttpRequestMessage(HttpMethod.Get, "http://goole.ca"));
            System.Diagnostics.Debug.WriteLine(response.StatusCode.ToString());
        }
		catch (Exception ex) 
		{
			System.Diagnostics.Debug.WriteLine(ex.Message);
		}
    }
}

As mentioned earlier, this is simply not supported. If you want to learn more details about the why and how you’ll have to contact the runtime team. This is not something that originates in .NET MAUI.
