Azure DataMarket Fixed Query
------------------------------------------------------------------------
A simple Windows Phone application using a fixed query against the Azure DataMarket.

In the Azure DataMarket, there are two methods to query a dataset: fixed, and flexible.  The supported query type is indicated on the dataset's Details tab.  This sample shows a very simple fixed query, which allows data access through predefined queries.  For fixed queries, a client class library must be downloaded, since the Add Service Reference is not supported for fixed queries (the client library is included in the sample).  This sample asumes you are using Visual Studio 2010 and have the Windows Phone SDK 7.5 installed.  This sample utilizes the Infochimps Trstrank (https://datamarket.azure.com/dataset/e35d3f16-838c-456e-8d1f-3616181a9b23) dataset for data--if you do not have an Azure DataMarket account, you will need to create one and sign up for this dataset to run the sample.

Although this sample calls the service from page-level code, you can use the identical code in MVVM.  The Dispatcher thread call is still needed, since callbacks run on a different thread in Windows Phone.
