    copied!<p>I'm confused. I've got a Silverlight project that currently runs and displays a list of servers from my mocked model (I am following the MVVM pattern).</p> <p>The interface is coded as follows:</p> <pre><code>public class GetServersCompletedEventArgs : EventArgs { public Exception Error {get; set;} public IEnumerable&lt;LicenseServer&gt; Results {get; private set;} public GetServersCompletedEventArgs(Exception error, IEnumerable&lt;LicenseServer&gt; results) { this.Error = error; this.Results = results; } } public delegate void GetServersCompletedEvent(GetServersCompletedEventArgs e); public interface IDataService { void GetServers(); event GetServersCompletedEvent GetServersCompleted; } </code></pre> <p>As you can see the CompletedEventArgs return the results as a IEnumerable. </p> <p>The problem that I am having is defining <code>&lt;LicenseServer&gt;</code> in such a way that I can stub it with fake data or populate the results from real data (ala ado.net data services).</p> <p>I've created a local class LicenseServer but the service always returns a different type of LicenseServer. </p> <p>I get an error:</p> <blockquote> <p>convert Unable to cast object of type 'DataServiceOrderedQuery[LicenseMon.LMonServiceReference.License_Server]' to type 'System.Data.Services.Client.DataServiceQuery`1[LicenseMon.Model.LicenseServer]</p> </blockquote> <p>Which I read as LicenseServer from the service reference cannot be converted over to the LicenseServer I've defined in my model class</p> <p>Why am I having trouble? Shouldn't I be able to develop my classes independently and be able to switch between a live database and my internally generated data? Am I approaching this the wrong way?</p> <p>Any code samples, explanations, links etc would be most helpful</p>
