Some help posting to ASP.NET Web API with C#

I have been playing with ASP.NET Web API. I am looking to see can I post to a method I have built which simply returns back the object I have POSTED:

On The Accounts Controller:

// POST /api/accounts
public Account Post(Account account)
{
   return account;

}

Code Used To Post:

    public void PostAccount()
    {
        // http://local_ip/api/accounts
        var uri = string.Format("{0}", webServiceRoot); 


        var acc = new Account();
        acc.AccountID = "8";
        acc.AccountName = "Mitchel Cars";
        acc.AccountNumber = "600123801";
        acc.SubscriptionKey = "2535-8254-8568-1192";
        acc.ValidUntil = DateTime.Now;


        var request = (HttpWebRequest)WebRequest.Create(uri);
        request.Method = "POST";
        request.ContentType = "application/xml";
        request.ContentLength = 800;

        XmlSerializer xmlSerializer = new XmlSerializer(typeof(Account));
        xmlSerializer.Serialize(request.GetRequestStream(), acc);

        var response = (HttpWebResponse)request.GetResponse();

        XmlSerializer serializer = new XmlSerializer(typeof(Account));

        var newAcc = (Account)serializer.Deserialize(response.GetResponseStream());

    }

I have removed any error checking or any boiler plate code to make it easier to read. This is strictly a spike just to under stand to to actually POST. My understanding is that you should write to the GetRequestStream(). All the reading and such seems to work ok but I never here back from the request.GetResponse();

If I do a simple get it works fine. I did see you can use a class called HTTPClient for doing this stuff but I can't use it as I need to get this working for WinForms, Silverlight and Windows Phone all based on .Net 3.5

Any help pushing POCO's to the server would be a great help, cheers!

You will need to close the response stream. Most examples I see also show setting the content length. You may be better to serialize to a memory stream and then use the length of that stream as the Content-Length. Unfortunately in .net 3.5 there is no CopyStream so you may have to write that yourself.

If you want to use the HttpClient, you can install the download the REST starter Kit. and use the DLLs as external DLLs
