Getting Image from a Stream (WMS) - image

Question

I'm developing a Window Phone 8.1 app. I'm trying to get an image from a Web Map Service and show it in a MapControl. I already get the stream with a http request and now I want to transform it in an Image.
How can I do this part? This is what I have:
Downloading the Stream:
HttpClient httpClient = new HttpClient();
HttpResponseMessage request = await httpClient.GetAsync("<URL>").ConfigureAwait(false);
Stream stream = await request.Content.ReadAsStreamAsync().ConfigureAwait(false);
Now I have the correct Stream from the request (it's a png image). Now I want to transform it in an Image. I already tried to use the FromStream() method but it seems that it's not supported in WP 8.1.
Can you help me please with this last part?

You could try something like this
HttpClient httpClient = new HttpClient();
HttpResponseMessage request = await httpClient.GetAsync("URL").ConfigureAwait(false);
using (Stream stream = await request.Content.ReadAsStreamAsync().ConfigureAwait(false))
{
MemoryStream memStream = new MemoryStream();
await stream.CopyToAsync(memStream);
memStream.Position = 0;
CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
{
BitmapImage bitmap = new BitmapImage();
bitmap.SetSource(memStream.AsRandomAccessStream());
img.Source = bitmap;
memStream.Dispose();
}
);
}
where img is an Image object defined in XAML.
BTW, a simple
<Image Source="URL" />
in XAML would also probably work for you if all you need is a bitmap as a source for Image.
