An update is available that provides additional features and improvements for ADO.NET Data Services in the .NET Framework 3.5 SP1 on a computer that is running Windows 7 or Windows Server 2008 R2

The Microsoft ADO.NET Data Services framework consists of patterns and libraries that enable you to handle Web services data that complies with representational state transfer (also known as REST) semantics. This update provides additional features that extend the functionalities that are in version 1.0 of the ADO.NET Data Services framework. The update is designed for the Microsoft .NET Framework 3.5 Service Pack 1 (SP1) on Windows 7 and on Windows Server 2008 R2.

This ADO.NET Data Services update includes the following features and improvements:

• The ADO.NET Data Services integrates into the Microsoft Office 2010.
  
  Built-in integration helps you expose Microsoft Office SharePoint Server data as a data service. Built-in integration also lets you access the data by using the ADO.NET Data Services client library.
• Support for custom data service providers is updated.
  
  The update helps you build an ADO.NET data service on any data source.
• The DataServiceCollection class is added to support two-way data binding.
  
  This collection class automatically tracks changes that are made on client-side objects. Changes are tracked for client-side objects that are created by using the ADO.NET Data Services client library.
• A new feed customization feature is provided.
  
  Feed customization lets you shape and change the structure of Atom feeds that are produced by an ADO.NET data service. When you change the structure of the Atom feed, third-party clients can consume feeds from an ADO.NET data service. Clients are people who consume an Atom feed that has a custom format.
• The binary large object (BLOB) support is improved.
  
  The BLOB support helps you stream BLOBs to a data service or from a data service. The BLOB support is also added to the ADO.NET Data Services client library. This feature lets you upload and download binary objects from an application that is created by using the library.
• Server Driven Paging (SDP) lets service authors limit the size of query results.
  
  This feature gives service authors more control over the network bandwidth and the time that are required to process requests.
• A new select query option enables query results to be projected into an arbitrary data type.
  
  This feature lets clients request a specific set of properties for an entity in a query. Reducing the number of properties in a query reduces the time and the network bandwidth that are required to process requests.
• A new option lets you set the number of entities that a query returns. When the option contains the total number of entities that are in the entity set, the query returns a partial result.
• The request-processing pipeline is optimized.
  
  The optimization provides service authors more ability to control and customize at different stages of query processing.
