I spent quite a lot of time with WCF Data Services (‘Astoria’/’ADO.NET Data Services’ as it was) in its first iteration. It’s a framework that I really like so I’m feeling a little guilty that I haven’t found time to completely revisit it as it becomes part of a ‘much bigger thing’ (i.e. OData ) and...

I did a short session on the Open Data Protocol (OData) last week at the NxtGen User Group and I thought I’d share the slides here. There are quite a few builds/animations in that slide-deck so I’d suggest that downloading it will produce a better experience than viewing it on SlideShare.

A big thanks to all the people who came along to my session at SQLBits today on ADO.NET Data Services and also to the organisers and community around SQLBits that made the event happen in the first place. I was there for most of the afternoon and it seemed like a fantastic event to me in a cool venue...

Tantalising post from the Astoria team.

Someone asked me if I had a simple sample of how to read/write documents into a database table using FILESTREAM in SQL Server 2008. I set about it. Firstly, I had to find out how to switch FILESTREAM on in the RTM of SQL Server. At times like this you need Bob Beauchemin to tell you how it's done and...

I produced a new set of short videos around ADO.NET Data Services and dropped them on to Channel 9. You can find them here; http://channel9.msdn.com/tags/UK and that list will grow as time goes in ( specifically, it'll grow if I can get the publishing system to publish my next 4 videos for me as it's...

This is similar but not at all identical to this post about LINQ to SQL because it's using a different framework and that has different capabilities. Someone mailed and asked how we can detect concurrency problems with Entity Framework in order to ensure that when we submit changes to the DB we first;...

I came across a bit of a glitch in using timestamps for checking concurrency violations in LINQ to SQL and thought I'd share. Say I've got a table like; create table Person ( id int identity primary key , firstName nvarchar(30), lastName nvarchar(30), timestamp ) so, we have a simple table that has a...

Following on from this last post , if I start to edit the data in the grid and change some value then the property value will change in the underlying class but nothing else will happen. That is, the NorthwindEntities class which is managing my data for me client-side ( which is derived from DataServiceContext...

Someone mailed me to ask whether I had a video on how to put together Silverlight and ADO.NET Data Services. I don't at the time of writing and I've also got a cold right now ( thank you, Microsoft Manchester office :-) ) so I thought I'd write something rather than record it. Let's run through a step...

Thanks to the people who came along to my talk on Entity Framework at VBUG in Bristol yesterday. I promised that I'd make the slides available and they can be found here for download in PPTX format and PDF format . This was more or less the same talk as I delivered at Southampton the week before so these...

Julie points to Danny and Danny points to the next CTP of Entity Framework - if you're interested in serializing the entities that Entity Framework returns back to you then you'll be interested in this; http://www.thedatafarm.com/blog/2008/03/28/HallelujahEntityGraphsWillBeXMLSerializable.aspx

...and followed Christian's great advice over here to get myself hosted inside of a console application; Self-Hosting Your ADO.NET Data Services ( Astoria ) Services took about 3 minutes. Now need to figure out what the heck I can do with this framework in its revised form.

Hmmmmmmm. If I had a pound for every time someone has asked me in the past "What's the best way to pass an array of values into a SQL Server stored procedure" then I'd have at least 4 pounds :-) I've seen people do it with strings. I've seen people do it with XML (both before and after SQL Server actually...

This is just a convenience - links to the posts that I've made so far around beta 2 of the ADO.NET Entity Framework. The Overview Video Entity Framework - Overview Video Note: This is also available on my Live SkyDrive in 5 pieces if that helps. "Getting Up and Running" Posts ADO.NET Entity Framework...
