Not sure what gives but for what ever reason creating the task and running it in main with t.start() does nothing. I don't get any errors it just stops when it hits the closing {} of Main(string[] args). The only thing different I added was user input on user name and password and I added an encryption method .

So I have the Main(string[] args then I have the following

` public async Task EncodePass(string password)
{

        byte[] bytes = Encoding.Unicode.GetBytes(password);
        byte[] inArray = HashAlgorithm.Create("SHA1").ComputeHash(bytes);
        return Convert.ToBase64String(inArray);
    }`

Then I have
`static async void HTTP_GET()
{

}`
