Completely non-blocking HTTP request C# ASP.NET

During my application's Application_Start() event I want to fire off a HTTP request to an address. I absolutely do not want any cost incurred by Application_Start() and for App Start to be delayed in any fashion. I do not care about the response from the request.

What is the most correct method for firing this request in a completely non-blocking fashion?

I would do something like this:

Task.Run(() =>
{
        using (var httpClient = new HttpClient())
        {
            httpClient.BaseAddress = new Uri("https://something.com/");
            var content = new StringContent("content");
            var result = httpClient.PostAsync("path/to/Service" , content);
            result.Wait();
        }
});

You can use WebClient.UploadStringAsync Method for this purpose

This method does not block the calling thread.

It can throw

  1. ArgumentNullException
  2. WebException

use it in this way

    var client = new WebClient();
    //remove comment from next line to execute some code after UploadString complete
    //client.UploadStringCompleted += new UploadStringCompletedEventHandler(function name to execute when finish);
    var data = "data to send";
    client.Headers.Add("Content-Type", "content type here");         
    client.UploadStringAsync(new Uri("http://www.yourDomain.com"), data);

I would recommend just firing the request asynchronously

using(var client = new HttpClient())
{
    client.PostAsJsonAsync("{url}",content)
}

for example will fire the request and continue
