The Origin of LINQ to SQL

History of LINQ to SQL

Not many Microsoft employees dare to publicly refer to WinFS as a black hole. Matt Warren does in this

I'll never forget Luca Bolognese's tearful announcement at TechEd 2004 that ObjectSpaces had acquired a dependency on WinFS and thus was postponed to the Longhorn/Orcas timeframe. WinFS and the Microsoft Business Framework/Project Green were two stakes in ObjectSpace's heart.

I refered to WinFS as a "black hole" in a forthcoming (July) feature story for "Visual Studio Magazine" about LINQ to SQL: "Redmond’s first attempt to deliver an O/RM platform appeared briefly in Whidbey (VS 2005 Beta 1) as ObjectSpaces and later vanished into the black hole generated by the demise of WinFS. Judging by the ruckus that Whidby participants raised when ObjectSpaces disappeared, data-oriented .NET developers definitely are O/RM enthusiasts."

I love: LINQ expression trees, LINQ generator-like behavior

I hate: Typing. IEnumerable<IEnumerable<IEnumerable<AnonymousType>>> just becomes too difficult to fathom. Bring back COmega * and + datatype identifiers.

I bet he referred to "preventing integration of LINQ to SQL into ADO Entities" by "political nightmare". If that was what he meant, congratulations for fighting this war and standing firm!!! Entities seems to have the same great project management skills that WinFS had and it is great to see the people that are commited to LINQ prevent a disaster this time around.

Maybe 'politcal nightmare' was a bit over the top. I would have actually preferred a better integration story between the two products.

Hello Matt,

Thank you for all the work you and your team mates put in the the APIs. LINQ (in general) and LINQ to SQL is forever going to change the way we think and write code.

I've recently held a 3½ hour internal session amongst developers in our company and the everybody agreed that LINQ is the best thing since sliced bread.

I also followed the development of ObjectSpaces and WinFS. Even back then, it was quite easy to see the black hole grow in strengh - sucking light and life away. Thanks for standing up to the internal political cauldrun and truly trying to make a big difference for developers out there.

Feel free to provide part 2 of the story btw. :-)

I bet it is because of Anders' name rather than bravery of smart (but powerless) developer like Matt.

After using Turbo Pascal and Delphi and C#, what can I say. C'mon, the guy knows more about developers' needs than almost anyone else who is active today. I bet WinFS suffered because they didn't have anyone like him. A handful of people can build big systems but even fewer can understand what developers want before launching a big project.

Having met Anders in person I can say that he's definately a guy that cares about developers. I'm sure the developers also want to improve life for all of us there - Anders may take a lot of the press, but I would seriously credit the entire team for LINQ.

It really doesn't matter who was responsible for pushing LINQ and related technologies such as LINQ to SQL - the techonologies just appeared at the right time in the right form.

Still looking forward to part 2 of the story btw. :-)

The Business Portal SDK (a precursor to MBF) shipped an object-relational mapping framework back in 2003 as part of MBS's Business Portal. It is even documented on MSDN.
