May .NET User Group Meeting - 2009
Colombo .NET User Group (CDNUG) meeting took place last Thursday the 7th May and Chandana did the first session on Windows Azure Services Platform.
The next session was take by me. My presentation was on 'LINQ to SQL to build your Data Access Layer.' On this session I talked about how to build a DAL using LINQ to SQL for a disconnected environment and highlighted some points to gain better performance as well. The full explanation and the code downloads can be found here.
It was interesting to see questions coming up from the audience and their enthusiasm on the subject. Hope it was useful and do feel free to buzz me if you find any thing interesting on this or have any queries.

Fantastic Job...
You had some unwanted in your demo, please use correct code and coding practices when doing demos.
Can you please point as to what were the unwanted in the demo..? I would really appreciate if you can pinpoint those to enlighten audience like me. One thing i would agree with the 'Anonymous' is exception handling.. Dont know if she could include all of those in the demo and make the audience life misarable.. :)
A proper data access layer would be able to send messages to underlying layers the details of the exception and the status of the operation too.
It is not considered a good thing to catch the exceptions and mute them.
Hi
Catching the exception and processing it accordingly is solely in the developer hands, in the demo im only pointing that there is a way of catching Concurrency Conflict exceptions by the ChangeConflictException.
Hope it helps,
Thx,
Gayani
