The HttpClient type is a newer implementation than the WebClient and HttpWebRequest.

You can simply use the following lines.

string myJson = "{'Username': 'myusername','Password':'pass'}";
using (var client = new HttpClient())
{
    var response = await client.PostAsync(
        "http://yourUrl", 
         new StringContent(myJson, Encoding.UTF8, "application/json"));
}

When you need your HttpClient more than once it's recommended to only create one instance and reuse it or use the new HttpClientFactory.
