This CTP is a preview of the set of features we are 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 we provided in v1.0 of ADO.NET Data Services by providing additional features. This CTP builds on and makes updates to the functionality provided in ADO.NET Data Services v1.5 CTP1.
As this is a CTP release, we recommend that you do 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 3
- Enhanced blob support
- Server-driven paging
- Projection Support (via the $select query option)
- A new "Data Service Provider" interface for custom providers
- Various bug fixes to V1.0 features
This release is separate from the Project Codename "Astoria Offline", Alpha Preview released on March 5, 2009. Installing this CTP on the same system as the Offline release will cause a conflict and is not supported. We strongly recommend that you do not install them together.
Installing this CTP on the same system as the ADO.NET Data Services CTP1 is not supported. You must uninstall CTP1 before installing CTP2.
It is possible to use this CTP with the Windows 7; 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. Using DataSvcUtil.exe for client-side code generation will also not be available on Windows 7. If you use the installer named ‘ADONETDataServices_v15_CTP2.exe’ you will receive a warning when you use the setup on a system with Windows 7 installed indicating a file is locked but the setup will not fail and the design-time components will not be installed. A separate installer named ‘ADONETDataServices_v15_CTP2_RuntimeOnly.exe’ is provided that installs only the runtime components and does not present the error message during install.
