Thank you David for this information. When I relayed your comments to a colleague of mine, he just "groaned" as he had been looking forward to the ObjectSpaces technology. Eitherway, we have downloaded the Versant demo stuff to get a feel for the product.

Best,



>ObjectSpaces was supposed to be released with Whidbey (Visual Studio 2005) but instead was cut out and merged into WinFS, to be released with Longhorn in 2006. Then WinFS was cut from the first release of Longhorn. Now, there was news last week that WinFS may be released well after Longhorn. So now we're talking 2008-9!!!

>The ObjectSpaces team has been disbanded (perhaps temporarily, but who knows). Effectively, for your strategic planning you have to consider it to be dead.
>
>Now, the interesting question is why did Microsoft kill ObjectSpaces? The official reason is that they didn't want to release "another" data access methodology that would confuse people. My guess is that some program managers do not understand Object-Relational Mapping. They are the ones that are cofused, not the customers!

>>>ObjectSpaces is dead. The two best alternatives are:

>>>1) Versant Open Access .NET: Clean programming API, Databinding, integrated Visual Studio Tools, won't be cheap.

>>>2) NHibernate: Open source but no integrated tools.

>>>Currently MM.NET supports the Table Module design pattern where the business object provides the methods that wrap a DataSet. I know Kevin has done some work to support O/R Mappers but I don't know how close it is to release.
>>>
>>>My personal preference is to avoid most of the code generators in this category. Your milage may vary.
