Some of the guys on the team have been knocking out videos to promote data explorer. The videos are high level, light hearted videos to explain the value prop of what we are doing. I think they are quite fun. Here are the first two that they have done...

Been quiet for the last week. I was busy trying to get some stuff done before a customer road trip in Europe. We were in Ireland today and will be in Stockholm tomorrow then Helsinki on Wednesday and Thursday ending with a meeting in London on Friday...

In Data Explorer, you do not always have to pull stuff in from external sources. You can write text and treat it as a data source or you can just write expressions in the formula bar. In this post we will play with some of the ways you can create data...

One of the things I really like about our bits is the fact that I can build little "libraries" by example. In this case I wanted to create an RSS Reader, a library we should have but do not yet have. We can use our existing capabilities, however, to...

When we did the demo at PASS we were showing the cloud experience. In my last post I had a video of one of our earlier iterations on the Montego client - the mashup component of Data Explorer. This next post shows a little bit about how you can reference...

Earlier this year (when we were still the Montego Project... i.e. before we become Microsoft Codename Data Explorer) we started with building out a client experience over our runtime. We still have both the client and the cloud service but we only...

14 months ago… It was 14 months ago that a bunch of us were sitting in a conference room with Dave Campbell reviewing some things he had been thinking about and some stuff we had been playing with. Our team had been sitting with some internal...

3 Years... that's right, three years since I posted on this blog. Wow, talk about not having much to talk about. Well... I am pretty excited about the stuff we are doing now and am eager to start talking about it. I have been chomping at the bit for...

Greg Young pointed out that I inadvertently perpetuated the canonical model stuff when I said the following: To be clear, one misconception is that we were trying to deliver on the old promise of canonical schemas, when we said one common model we...

So, it seemed like it would be useful to talk a bit about why we built the EF and the EDM, what we think it is and where we think it is going. A lot of docs exist on the EF and EDM. One can find many opinions on both all over the web. I wanted to take...

We just wrapped up our first iteration of V2. We are shooting to get another iteration in before PDC and are still working on how we can get early bits out to customers outside of the rhythms of the CTP's and such. One of the nifty things in our...

I spent some time this week with Scott Bellware. He and Greg Young have been in town talking to the EF team about Test Driven Development, Behavioral Driven Design and Domain Driven Design. On Tuesday night we went out to dinner and had a long chat...

There is a wonderful debate going on right now on the entities wiki . You need only read some of the comments on the front page to see that different people are sharing their perspectives on application architecture, methodologies and patterns. For a...

Although we want all folks from the team to be able to post content as they saw fit on the EF Design Blog , we wanted someone on point to be the person who did actual care & feeding of it. Alex James , one of the PM's on the team is the person on...

So,  I just threw up a new wiki to collect patterns and practices from the developer community that can help inform our understanding of real world developer scenarios. Where did this come from? ... I had a good thread with Scott Bellware where he...

I just exchanged email with Martin Fowler about the term Lazy load. The interpretation that we on the Entity Framework team had about Lazy Loading was that on a given query we would not "eagerly" load an entire graph (i.e. load a customer, their...

We just threw up a screencast on the EF design site to complement the POCO feature design notes. This was a prototype that Mirek (one of the developers on the team) has been doing around a full POCO enabled state manager. I am hoping that we can get early...

We just pushed the first piece of content to the EF Design Blog . This one is a "Feature Design" posting about the POCO feature that we are working on for V2. Sometime today we hope to get a quick screen cast of a prototype up. We will actively...

So, It's been a long, long time since I have posted anything on my blog. Reality is I tried to maintain a blog where I thought I could come up with wonderfully profound things to share with the world but clearly that was not the case. Having said that...

So, I am a self-admitted “value layer” bigot. I spend a lot of my coding time in ADO.NET Entities building stuff on top of our value layer (in other words working directly against Entity Client without using our object abstractions). Recently...

The latest Orcas CTP has ADO.NET Entities available and we have posted some samples . The bits available with the Orcas CTP do not have LINQ support or out of the box tooling, if you want LINQ support then you should pull our August CTP and Tools ...

We shipped our CTP last week ( ADO.NET August CTP ). Pretty cool. I guess I should blog some on things like EDM, Metadata, Mapping and the like. For now I will point out some interesting blogs: Murali made a large post on queries There's the channel...

Shyam Pather, a dev lead on the ADO.NET effort just posted on the Data Access Blog he has done some screencasts with our current bits: Part 1 Part 2 enjoy...

I am jazzed by the fact that people are reading our docs and posting opinions. The feedback, positive or negative, is always good stuff for us to consume and internalize. One thing that I wanted to talk about, having read many of the blogs out there,...

In case you have not seen this, Sam and Anders are on Channel 9 talking about LINQ, LINQ to SQL and LINQ to ADO.NET.
