The Microsoft ASP.NET 3.5 Extensions Preview CTP shipped in December of 2007 and included a client library to facilitate access to ADO.NET Data Services ...

Design Notes: URI Containment in Astoria

DB Blogs December 21, 2007 Dec 21, 2007 12/21/07

Problem statement Today in Astoria if you have two entity types that are functionally in a containment relationship, you still see a top-level entity set for the instances of the contained type, and further the URLs for instances of the contained types that go through the parent type contain redundant information. For example, assuming a ...

LINQ to ADO.NET Data Services

DB Blogs December 11, 2007 Dec 11, 2007 12/11/07

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 platforms.  The .NET Framework an ASP.NET AJAX libraries shipped with the Dec 2007 CTP of...

ADO.NET Data Services Dec2007 CTP – Validation and Access Control

DB Blogs December 10, 2007 Dec 10, 2007 12/10/07

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, we thought the topic would be a good one to kick off a series of blog posts about ...

Viewing Data Services Responses Using Atom Serialization in Internet Explorer

DB Blogs December 10, 2007 Dec 10, 2007 12/10/07

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, this industry standard format can be used for general purpose data exchange...

Astoria data sources and system layering

DB Blogs September 27, 2007 Sep 27, 2007 09/27/07

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 back for a second first and establish why certain data sources are interesting. Why does ...
