Hello Mark, Thank you for your proposal. Yes, it would be useful to test using your servers in the case my hosting site would not be able to "keep the pressure" of coming data requests, and in the scenarious when several servers would need to communicate - something like distributed workflow (using WF). BTW, my sample site works OK now: Here is a "query" to retrieve Shippers. http://shamils-4.hosting.parking.ru/NorthwindNetDataService/NWNetDS.svc/Shipper and this one for Categories http://shamils-4.hosting.parking.ru/NorthwindNetDataService/NWNetDS.svc/Category Note: those queries return ATOM feed therefore ATOM feed interpretation should be switched off in your browser. Such queries can be used to do all the data manipulation including CRUD operations AFAIU. I haven't yet checked/read how to make such quieries secure but I assume that this feature is implemented already, and I need just to switch it on. The returned data can be of different structure ATOM feed, JSON etc. - and they can be consumed by many types of clients including AJAX (KavaScript) etc. In other words once you get ADO.NET data Service published (no any programming was needed in my simple sample case) you can immediatley start developing custom applications/clients. As for performance - it should be good enough I expect - at least for business areas and the applications we develop. AFAIU ADO.NET Data Services internals can be fine tuned for special case to increase response time. We can test performance - we can write test clients and run them on our PCs querying the above sample service or the one you can install on your server - to compare response time from public ASP.NET hosting site I use or dedicated servers you have - I plan to publish this sample service on our CodePlex Northwind project area... Is ADO.NET Data Services the future? - that's is the question to MS - I do not have a Crystal Ball :) For sure it's very useful and promising technology.
