Hi Shamil:
I have been watching this thread for a bit and was wondering, if proceeding
along this direction is in fact tying the designers and users to a very
proprietary desktop and set of BE services?
Just to get much of the apps running requires the very latest patches and
specific downloads, products that are not integrated into the default
Windows OS. Only the most carefully managed office location would be able to
even run this technology.
>From my point of view the following is the reality:
1. On most sites I am just the contractor and not as the head IT guy.
2. Clients want to hire me not marry me.
3. Many sites using 'mixed' desktops (Windows/Mac/Linux).
4. The trend is towards 'portability' on cross-platform environments.
On the other hand, this is all great fun technology and I have been very
much enjoying this thread.
Jim

Hi All,
I have found a good sample to consume ADO.NET Data Services using
SIlverLight 2.0 - here it's:
Using Silverlight 2 With ADO.NET Data Services
http://msdn.microsoft.com/en-us/magazine/dd569758.aspx
I will try to make something like that live tomorrow - time to sleep here.
Thank you.

ADO.NET Data Services can be used in heavily distributed workflow
scenarious, with support of distributed transactions etc.etc. Workflows are
designed and programmed for such applications using Windows Workflow
Foundation (WF). "Not data" services are developed using Windows
Communication Foundation (WCF) (and ADO.NET data services are also driven by
WCF services AFAIU)...
