How can you add a Certificate to WebClient (C#)?

Question

I know it is pretty simple to add a certificate to a HttpWebRequest. However, I have not found a way to do the equivalent using WebClient. Basicly, I want to send out a POST with a specific certificate using WebClient.

How would you accomplish this exact code using WebClient:

    var request = (HttpWebRequest) WebRequest.Create("my-url");
    request.Method = "POST";
    request.ClientCertificates.Add(new X509Certificate()); //add cert

You must subclass and override one or more functions.

class MyWebClient : WebClient
{
    protected override WebRequest GetWebRequest(Uri address)
    {
        HttpWebRequest request = (HttpWebRequest)base.GetWebRequest(address);
        request.ClientCertificates.Add(new X509Certificate());
        return request;
    }
}
