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...

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.

I came upon the the IMDB bottom 100 film list while reconciling a lunch time wager pertaining to Cool as Ice .   My opinions of the list   Spice World should not be on this list.   If you have seen it, you will agree...

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...

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...

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...

There have been several internal email threads here at Microsoft about how ObjectSpaces will fit into the world of SOA. Below I have included my internal reply to one such post on the subject. Note - my reply is not intended to be a manifesto on the subject...

Hello All - since this is my first post on http://weblogs.asp.net since moving from the gotdotnet blogging site, I decided to revive my original “introduction” post. My name is Andrew Conrad, I am a Software Design Engineer with the Sql...

Last week I was visiting Fargo to do some work with the Microsoft Business Frameworks team. In the weeks leading up to the visit, our co-workers in North Dakota harassed us Redmond’ites with a variety of emails explaining how cold it had become...

A data layer is all about abstracting the explicit boundary between the application/ domain model and the persistence datasource. Although this boundary can never be totally transparent, the data layer does its best to expose the persistence data in a...

While preparing my talk for Teched, I figured out a trick for getting simple sub-tree pruning when running XPath queries via SqlXml.   Sub-tree pruning is the ability to filter sub-trees of an Xml hierarchy.   For example, let’s say I had...

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 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...

Scott Bellware has an interesting post about Lazy Load in ORMs. IMHO, I prefer eager load of all scalar values and load on demand (lazy load) for all complex objects, even when the cardinality is M..1 and 1..1. And once something is loaded, it stays loaded...

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...

IUpdatable for Linq to Sql I have had an implementation of IUpdateable for Linq to Sql about half done for quite some time now. Yesterday I decided to bite the bullet and finish it up. Below I have included that code. I’ve done some light testing...

I just finished " reading " an incredible book – Moneyball: The art of winning an unfair game .  This book is about the Oakland A's , and how it's general manager, Billy Beane, has made the team successful in a market place (major league baseball...

About a 1 ½ years ago, I decided to purchase an iPod and get a membership with audible.com (which I highly recommend) in an effort to “read” more. Since the birth of my second child in mid-2003, my amount of free leisure time had been drastically cut...

It has been a while since I blogged, almost three months. So what have I been up to – well actually quite a bit. I have left the WinFS client API team and moved back to my old group (formally the WebData team) now called Dataworks. To make a long story...

Back in the game...

  From a comment on my “ObjectSpaces Myths” post:   “ However it's NOT a myth that ObjectSpaces is spec'ed to be 40% slower than DataSets, correct?”   The comparison is actually not that...

Don Box is looking for an “a ha” moment on why he should use SqlXml. Unfortunately, he probably won't find it while building his new Blog engine. The reason for this is that the real usefulness for SqlXml shows itself in development scenarios...

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...

System.Data.DataSet contains some very significant performance improvements over prior versions – particularly for large result set scenarios. In particular, Highly efficient Binary Remoting -- For large Dataset, orders of magnitude better than v1.x Row...
