Asynch WCF Data Services / OData

I am trying to write asynch call to a wcf data service but not sure how to read the object returned.

public IQueryable<T> Read(string TableName)
    {
        IQueryable<T> OdataResult=null;            

        IAsyncResult asyncresult = context.BeginExecute<T>(new Uri("/" + TableName, UriKind.Relative),
            (result) =>
            {
                Dispatcher.CurrentDispatcher.BeginInvoke(new OperationResultCallback(delegate
        {

            var result1 = new DataServiceCollection<T>(context.EndExecute<T>(result));

            OdataResult = result1.AsQueryable<T>();

        }), null);
            }, null);

        asyncresult.AsyncWaitHandle.WaitOne();

        asyncresult.AsyncWaitHandle.Close();

        return OdataResult;}

ODataResult is always giving me null :(

Solution

  • I have used "Task" instead of "Dispatcher" and it shared the Data via "Result" property with My main thread.
