I think one should use singleton pattern to avoid having to create instances of the HttpClient and closing it all the time. If you are using .Net 4.0 you could use a sample code as below. for more information on singleton pattern check here.

class HttpClientSingletonWrapper : HttpClient
{
    private static readonly Lazy Lazy= new Lazy(()=>new HttpClientSingletonWrapper()); 

    public static HttpClientSingletonWrapper Instance {get { return Lazy.Value; }}

    private HttpClientSingletonWrapper()
    {
    }
}

Use the code as below.

var client = HttpClientSingletonWrapper.Instance;
