While we worked hard to make it such that any HTTP client can easily consume an ADO.NET Data Service, we are also working on client libraries for the .NET Framework, Silverlight and ASP.NET AJAX to up the level of abstraction clients written on those...

Note: This post refers to the CTP available here . When building frameworks to expose and consume data on the web, access policy and data validation are always one of the first topics discussed during the design process, at conferences, etc. Given this...

The default serialization format for ADO.NET Data Services is now Atom instead of alternative XML-based formats we experimented with in previous releases. In short, we chose this format because when combined with the Atom Publishing Protocol (APP) specification...

The first CTP of the production version of ADO.NET Data Services is now available for download here as part of the ASP.NET 3.5 Extensions preview release . We are referring to this as the "first CTP" because the releases of Astoria prior to this were...

A new name, but goals stay the same As per our last blog post, we just finished a round of presentations on Astoria at Tech Ed EMEA, Tech Ed Africa, Dev Connections and finally Dev Teach. Thanks to everyone that attended our sessions and who stopped by...

A few members of the Astoria team will be presenting on the technology in the coming month. We look forward to meeting those attending the conferences and discussing the project with you. Presentations include: Pablo Castro @ Tech Ed: http://www.mseventseurope...

The question is: what data sources should Astoria support as inputs? Should we allow ADO.NET Entity Framework only or open up more? If we open up more, how does the system need to be layered to enable the use of those alternate data sources? Let me step...

Deciding on something that becomes a public interface of a developer-oriented technology is a tricky task. Not only does the resulting design need to be correct and complete, but also there are various aspects that are more around aesthetics and personal...

Some time ago we shipped Visual Studio 2008 Beta 2 and a couple of weeks later we added the ADO.NET Entity Framework Beta 2 release as well as the first CTP of the tools for it. Once all of the frameworks/tools were in Beta 2 we got a bunch of email ...

The goal of Astoria is to make data available to loosely coupled systems for querying and manipulation. In order to do that we need to use protocols that define the interaction model between the producer and the consumer of that data, and of course we...

It's amazing to see how many people are building great things with Astoria so early in the cycle. We talk with folks in the development community often and we hear stories that range from teaching classes, to giving talks, to building experimental systems...

It’s been some time now since we switched from “incubation mode”, where it was just a couple of guys hacking stuff, into “production mode”, were we are building a product, following good engineering practices, spending a ton of time on every design detail...

At the Mix 2007 conference we announced an Astoria CTP which included two major pieces: CTP bits you can download, install and run on your own systems and an experimental read only online service over a few sample (northwind, etc) sets of data that we...

We have been looking at various options to ensure that the design of Astoria truly reflects the requirements of the day to day challenges that our developer community faces when building real-world web applications and services. We would like to start...

Welcome to the Project Astoria Team Blog! The Astoria team (part of the “ Data Programmability ” (DP) team within the SQL Server organization at Microsoft) is responsible for analyzing how current and next generation internet enabled applications use...
