This CTP is a preview of the set of features Microsoft is considering shipping with the next version of ADO.NET Data Services. This CTP targets the Microsoft .NET Framework 3.5 SP1 and extends the functionality Microsoft provided in v1.0 of ADO.NET Data Services by providing additional features. The features in this CTP may not be included in the .NET Framework 4 or Silverlight 3 when they ship.

As this is a CTP release, you should not install this release on your primary development computer. Also, be aware that the features that ultimately ship with the final release of v1.5 may be different than the features included in this CTP.

The features included in this CTP are:

• Row count
• Feed customization (aka “web-friendly feeds”)
• Data binding for WPF and Silverlight 2
• Enhanced blob support
• Server-driven paging
• A new “Data Service Provider” interface for custom providers
• Various bug fixes to V1.0 features

Install Notes:
This release is separate from the Project Codename “Astoria Offline” Alpha Preview released earlier this month. Installing this CTP on the same system as the Offline release will cause a conflict and is not supported. You should not install them together.

It is possible to use this CTP with the Windows 7 Beta; however, design time support integrated with Microsoft Visual Studio 2008 SP1 or Microsoft Visual Web Developer 2008 Express Edition will not be available on Windows 7 Beta. Using DataSvcUtil.exe for client-side code generation will also not be available on Windows 7 Beta. You will receive a warning if you use the setup on a system with Windows 7 Beta installed indicating a file is locked but the setup will not fail.
