Data connection issues with Astoria / Northwind back end Demo

[odx]

Hi There

I'm hoping that someone out there will be able to help with what i'm sure is a rather stupid question,  please bare whith me as i am very new to all this.  I am using Visual Studio 2008 &  MSSQL Server 2008 (full - not express)

I'm trying to run the  sample of the Northwiind back end Demo ... Demo / Blog found here

My problem is that i get an exception thrown at line below in bold. (line 163 of NorthwindDataSource.cs).

Error message  from Visual Studio 2008 = DataServiceQueryException was unhandled byuser code


        /// </summary>
        private static void EntitiesLoaded<T>(IAsyncResult result, Collection<T> entities)
        {
            DataServiceQuery<T> query = result.AsyncState as DataServiceQuery<T>;

            IEnumerable<T> categories = query.EndExecute(result);
            foreach (T e in categories)
            {
                entities.Add(e);
            }
        }


Nay help you can give would be great

Thanks

Hello odx,

We are not sure what is causing this issue. It might be something related to the connection with your SQL database as this method is in response of the whole data retrieving from database. I suggest you try to run only the Astoria date service by browsing the NorthwindBackEnd.svc file from your solution.
