Async await in Windows Phone web access APIs

Question

Is there support for the async/await pattern in WP8?

I need to get XML from a web-based API and it looks like that WebClient or WebRequest

I had the same issue and I found this and helped me

private async Task ExecuteAsync(RestRequest request)
    {
        var tcs = new TaskCompletionSource();
        _client.ExecuteAsync(request, resp =>
        {
            var value = JsonConvert.DeserializeObject(resp.Content);
            if (value.ErrorCode > 0)
            {
                var ex = new ToodledoException(value.ErrorCode, value.ErrorDesc);
                tcs.SetException(ex);
            }
            else
                tcs.SetResult(value);
        });
        return await tcs.Task;
    }
