ADO.NET Data Services Framework Beta 1 is Live!

So I guess there still aren't any options for getting total record count when doing paging, eh? Doesnt seem like that functionality is going to make it into 1.0 at all. I just really cant understand how something that seems like such a core requirement to me isnt going to be addressed for the 1.0 release. Maybe I'm the only one that thinks its required and everyone else is OK with doing next / prev paging solutions. Ah well.

Eric: you can be sure we had long serious conversations about this...however, our focus is on ship soon, ship often. There will be always more features that we'd like to add. We prefered to deliver this version of Astoria as part of SP1, and then in the next iteration we'll include a number of the things that didn't make this time around. For this case we thought that next/prev was "good enough"...I understand that it's not perfect for everybody.

Quick question - is there any reason why Astoria won't work with AdventureWorks 2008 sample database? I can get it to recognize some tables (Person.EmailAddress, Production.Product), but not others (Person.Person, etc.) I haven't found a pattern yet - am I missing something? Thanks.

Mike: assuming you installed SP1 beta 1, the EDM wizard pops-up when you do File -> Add New Item and choose the "ADO.NET Entity Data Model" item template. The wizard will guide you through the rest of the process.

As for the LINQ to SQL case, one thing that might be happening is that not all the tables may result in CLR types that follow the Astoria default convention for key properties, so you may need to use the DataServiceKey attribute to indicate which properties should be treated as keys on each table (at least each table that didn't show up). DataServiceKey is a class-level attributes to enable these scenarios, you can use a partial class to put the attribute and pass the name(s) of the key property.

Thanks Pablo, there's currently no "ADO.NET Entity Data Model" item template showing up. I do have .NET 3.5 SP 1 beta 1 and VS 2008 SP 1 beta 1. I'm uninstalling and reinstalling both now. I'll have a look at the data types for the tables it's not pulling via LINQ to SQL Classes, but the tables I'm pulling don't appear to have any of the new 2008 data types in them. I'll have a closer look and get back to you. BTW, the LINQ to SQL Classes method appears to work great against SQL 2005. Thanks again for the help.

Hi!

Thanx for the new stuff! Is entity polymorphism scenario supported in this release? I've noticed that the .OfType<T>() query operator isn't. I hope this will be a v1 feature because my entity models heavily relies on inheritance.

Re: polymorphism, yes, Data Services can include schemas that use inheritance. OfType<T> should work if used within the limitations of queries translatable to URLs. What is your scenario? What error do you get?

Hi Pablo!

I haven't got enought time yet to test the beta bits. It might be my fault not data service's. :) Glad to hear that it finally supported. Today I gonna give it another try!

Just for the record, I was at Summit, I know some members of your team. I've been developing a full featured change tracker databindable client library for Astoria. I have a friend in the VSX team (Istvan Novak, author of the DiveDeeper blog: http://www.architekturaforum.hu/blogs/divedeeper/), so Visual Studio integration is on the roadmap. I've been working a real life solution and article also to demonstrate power of the 3.5 era, including EF, Astoria, WCF, WPF and Silverlight 2.0. It will be published on a hungarian .NET site, but English version is coming soon.

I (we) only need a better documentation of Astoria. Entity Framework already have an early version on MSDN, but Astoria's short introduction on asp.net is poor. Today if we want to know something we have to use Reflector. Or MSDN forum, but it's nine hour later at Europe you know, so it's not too fast information gathering method. :)

Again, thank you for the new stuff! Today I'll give it a try!

I make a db with one table. That table has a primary key. I create a model. I run. I get:

The method 'Skip' is only supported for sorted input in LINQ to Entities. The method 'OrderBy' must be called before the method 'Skip'.

Any ideas?

Then I pressed F5 and clicked on my table.

Hi Peter,

When you create your web site, please make sure you choose 'Dynamic Data Entities Web Site' and not 'Dynamic Data Web Site' (which is for Linq To Sql).

thanks,

Could you please drop a note here when the docs are ready? I need to get up to speed for SL integration.

Thank you guys for bringing this platform. Amazing, it was like yesterday, when Pable was demoing his ideas about Astoria on the first video, and not it's part of .Net.

Way to go Pablo...

Regarding the missing Entity Data model problem.... I ran into this, tried the devenv /setup suggestion, looked harder (again) for problematic beta or KB updates that needed to be removed, and finally (!) reread the release notes... no luck...

THEN! just as I was about to uninstall/reinstall, I recalled the release note about the SP1 not saving your settings... and guess what one of the default settings is for a VS2008 project? .Net *3.0*.

Yesss!! No reinstall for me on my Saturday afternoon, changing the project type to .net 3.5 did the trick.

Hope this helps others get going.

What can users like myself, JB, Eric Smith, PWelter, Michael DB, jb_tiburon, and countless others do to ensure the that a method to return record count for a query makes it in to the next release?

What do we need to do? A petition? What will it take to make these cries heard?

re: ADO.NET Data Services Framework Beta 1 is Live!

Nick: we've heard you loud and clear. We know folks want this and we have a work-item for it in our all-up features database. I want this to make it to the next release as much as you guys. That said, as a matter of policy we never guarantee that a given feature makes it to a particular release. Things happen that shuffle priorities around in unplanned ways.
