ADO.NET Data Services for Silverlight 3 Update CTP3 now available for download
A few weeks back, we announced our Data Services update to .NET 3.5 SP1. That release introduced many new features. We are now releasing the Silverlight counterpart, ADO.NET Data Services for Silverlight 3 Update CTP3. This CTP updates our Silverlight client assembly to make use of the new features. This release is just a CTP because we will be shipping with Silverlight 4. However, we wanted to give our users an early opportunity to try out our new features in Silverlight. This is a side by side update. We recommend that you do not replace the original assembly. Instead, just extract the files and reference it fr...
Compatibility Note: SharePoint 2010 Beta & Data Services Update
If you want to try out Data Services with the SharePoint 2010 Beta today you have to use CTP2 of Data Services v1.5, because unfortunately the Data Service RTM version, aka the Data Services Update for .NET 3.5 SP1 is incompatible with the SharePoint 2010 Beta. This is a point in time issue – when SharePoint RTMs it will work seamlessly with the Data Services Update for .NET 3.5 SP1. Alex JamesProgram ManagerMicrosoft

Server Paging in Data Services
The Data Services team recently released an update to.NET 3.5 SP1 that adds a number of features to data services – we are calling this update Data Services V2.

In this post, I’ll introduce you to the concept of page limits, I will teach you how to set limits on a service, and finally I will teach you how to work with the partial pages in the data services client.

Getting Started with the Data Service Update for .NET 3.5 SP1 – Part 2
In Part 1 we created a Data Service that exposes V2 of the OData Protocol, in this post we will create a WPF application to consume our Data Service. Walkthrough: Step 1 – Update Code Generation Settings: The Data Services Update is basically a patch to .NET 3.5 SP1, so it can’t break existing projects, this means we need a way to opt-in to the new Code-Gen features. To do this after you installed the update you need to create two environment variables: Set dscodegen_version to 2.0. This tells CodeGeneration to generate classes that can leverage V2 protocol features. Set dscodegen_usedsc to 1. This tells CodeGe...
