Tantalising post from the Astoria team.

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;...

Thanks a lot to the people who came along to my Entity Framework talk at the Oracle and .NET Special Interest Group in London today. As promised, I've uploaded the slides in PPTX and PDF format if you need them for anything.

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

I did a talk down at DevWeek this afternoon about ADO.NET Entity Framework. Whilst it was a small room, it was full and I had a great time - hopefully if you attended then you enjoyed it too and got something useful out of it. Thanks for all the questions :-) As promised, the slide-deck is available...

Someone asked me about this so I thought I'd share here. The question was around how you can work with database generated values and have them returned to the client after the insert. My experiment ran like this. I created a table; create table test ( id int identity primary key not null , someColumn...

I have a mail from Tim on the EF team that I've had for a little while. I'd asked a question about mapping and he'd given me an answer saying something like "Oh, you could always do X, Y, Z" and I'd left this mail in my inbox for a while because I've been distracted and also because I didn't really understand...

I made a few more videos; ADO.NET Data Services - Querying with LINQ ADO.NET Data Services - Query Interceptors ADO.NET Data Services - Service Operations to go with these videos . Note, there are some "technical difficulties" at the moment in getting some of those videos to play in the Silverlight player...

I made a few videos about Data Services. I have plans to make a few more as well but (as always :-)) I've got distracted by something else so, for the meantime; ADO.NET Data Services - Surfacing Data ADO.NET Data Services - Querying with URI's ADO.NET Data Services - A Basic .NET Client ADO.NET Data...

Just a quick link to make this easier to find; ADO.NET Data Services Silverlight Add-On

I keep searching the web to find this useful document about Data Services; Using ADO.NET Data Services CTP1 so I'm linking to it here for my own sanity :-) Maybe it's installed as part of the SDK. Maybe it's on another website somewhere but I can never find it when I want it (well, ok, I can now I've...

One of the things that I briefly mentioned in this post was the idea that because Data Services sits atop of WCF you can plug in a ServiceAuthorizationManager which gets a chance to look at every request before it gets dispatched into your data service. Whilst you can write explicit interceptors that...
-
Take some of this with a pinch of salt - just some thoughts I had whilst playing with controlling access to an ADO.NET Data Service, haven't necessarily got it worked out just yet. When you first create an ADO.NET Data Service, one of the things that you'll encounter is the need to configure access to...

This is one of those posts where I might not have thought the whole thing through but I was thinking about authenticating clients with ADO.NET Data Services. In Data Services, we have the URI of the resource and an XML/JSON response so for authentication there really isn't anywhere to put credentials...
