Man vs Code

In the original Linq CTP and the first Orcas Beta, we included a DataSet specific Linq operator called CopyToDataTable<T> (It was called ToDataTable at one point also).  For Beta 2 of Orcas, we ended up restricting this method to only work...

Late Sunday night we released the first public preview of ASP.NET 3.5 Extensions. For information on the release, see ScottGu's announcement . As part of that preview, we released the first CTP of the production version of Project Astoria. For details...

A number of people have asked me for a VB version of the CopyToDataTable<T> sample I wrote a few months back.   Unfortunately, between getting some skiing in (lots of snow in Washington this year!) and getting Astoria ready for Mix, I...

I will be posting more about the changes to the ObjectSpaces release plans in the near future- but in the mean time, I wanted to make sure everyone was aware of that we are willing to listen to any and all feedback about the changes. The following lists...

In V1 of .net, value types could not be null. Since, this was contradictory to relational databases use of null, the DataSet needed to have a concept of nullable value types – hence DBNull was invented. DBNull is simple type in the System namespace. It...

Some interesting comments from my entry on new DataSet features… Please nix the DataSet from the framework entirely and re-focus on the domain-oriented data access work you were doing prior to Tech-Ed 04. If that's not possible, please have the Visual...

Nic Wise (of Fast Chicken fame) has written a nice little introduction to ObjectSpaces .

DataSet... Linq... hmmmmmmmm.

I have to say I disagree with Ingo’s comments about preferring “ bare bones Sql ” over O/R mapping technology. IMO, the two topics are orthogonal. Data Access is all about solving high level use cases. There are no rules out there...

At the Mix07 conference this week, we will be announcing Project Jasper – aka Dynamic ADO.net. Available immediately is the initial CTP (Community Technology Preview) release for the project. What is Project Jasper? Here is the high level description...

Ok… as with anything, the initial effort is always the hardest – so I am just going to jump right in and start hacking. My name is Andrew Conrad , I am a Software Design Engineer with the Sql Server group at Microsoft.   For the past...

As someone pointed out, I have been referring to ObjectSpaces as supporting true POCO – which is technically incorrect. ObjectSpaces does prescribe the usage of ObjectHolder and ObjectList for delayed load cases (more of the merits of delayed loading...

The question “ Is Jasper useable from c#? ” came up on the Jasper forum . The short answer is – We designed Jasper specifically for CLR languages with late-bound facilities such as VB and IronPython. C# doesn’t currently support late-bound calls and...

SqlXml WR3 sp2 RTM has been released.   Actually, it was released late last week - but I have been so busy I haven't had time to post about it.   But that is another story for another time.   In my opinion, this should...

Back in the game...

  There is a known problem with pre sp2 of SqlXml WR3 when running with IIS 6.0 (Windows Server 2003).   Basically, SqlXml virtual directories do not work properly when using the “Configure IIS Support” tool to set up SqlXml virtual...

We have begun the initial planning for the next version of the DataSet (post VS 2005). If you have a feature you would like to see, let me know. I can also pass on feature requests for other components in System.Xml and ADO.net to the proper folks.

Got a very observant comment on my ObjectSpaces and WinFS Part 2 entry: My big scare is that merging ObjectSpaces and WinFS will restrict me from using OS as the persistence layer in places where the customer doesn't have and won't upgrade to the latest...

Some interesting comments from my old team.

Over the past few weeks I have posted a couple of samples of implementing IUpdateable for non-EF DALs so those can be used as data sources for ADO.NET Data Services.  A handful of people have asked me why this is interesting, so I now realize I should...

Over the last week or so we have been trying to gather information on what developers are saying about Project Jasper. (This, even in the age of rockin’ search engines is a lot harder then one thinks). As part of this, I have seen a handful of interesting...

The Astoria team is hiring! We have positions open for Developers and Program Managers. Currently, we are finishing up V1 and planning for V2, so it is a great time to join the team. For V2, we are thinking about expanding the project into new areas ...

Peter Qian, the newest member of the ADO.NET Data Services, now has his own blog . In his initial post , Peter talks about the row count feature we included with v1.5 of ADO.NET Data Services.  He was one of the main designers and the implementer...

Based on feedback from Robert Fonseca-Ensor , I have made a bunch of bug and performance fixes to the IUpdatable implementation for Linq to Sql and posted those to code gallery .  Rob is also now my first official contributor to the project. As part...

Finally got IUpdateable.ResetResource() for Linq To Sql working correctly.  This means that REPLACE operations are now working correctly.  I have uploaded those changes to code gallery . Going forward all changes to the code with be available...
