Consuming a WCF Rest Service with WP7

I have a WCF Restful Service that returns JSON objects that my iPhone and Android apps consume nicely. This is my first attempt at building something like this and I left WP7 till last as my background lies with C# and VS2010. But it seems it’s not going to be a simple as I had guessed.

So I guess I have three questions:

1, Can I consume JSON objects in WP7? If so does anyone know of a tutorial? 2, if not, can I use the existing service and build some new contracts for consumption in WP7? Or,

3, do I need to build a whole new service?

Option one is most desirable but either way, I need to develop for all three operating systems so does anyone know the best type of model to bring this all together??? Cheers,

Mike.

I find a totally wcf-based approach more interesting.

This is a good post that addresses this issue http://blogs.msdn.com/b/carlosfigueira/archive/2010/04/29/consuming-rest-json-services-in-silverlight-4.aspx

  1. Yes, but not with the channel factory / proxy programming model which you may be used to with WCF. REST services are usually consumed by using some simpler classes such as WebClient. You can use the JSON libraries (DataContractJsonSerializer is in the WP7 profile) then to deserialize the data you receive. Even the untyped JSON (the System.Json classes from the System.Json.dll on Silverlight), while not officially in the profile, they kind of work on WP7 as well (I've seen a few people simply referencing the SL library on a WP7 project).

  2. If you want proxy support, you can add a new endpoint to the service using BasicHttpBinding, which is supported in WP7; if you don't need it, see 1).

  3. No. See 1) and 2).

Try this to deserialize a JSON object:

public static T Deserialize<T>(string strData) where T : class
{
    DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T));
    byte[] byteArray = Encoding.UTF8.GetBytes(strData);
    MemoryStream memoryStream = new MemoryStream(byteArray);
    T tRet = serializer.ReadObject(memoryStream) as T;
    memoryStream.Dispose();
    return tRet;
}
