“Astoria Offline” is designed to provide an end-to-end solution for authoring of offline applications that use data from data services, either within a corporate network or across the Internet. This download provides the tools and runtime components necessary to create the client and server components of the system and create sync-capable databases (or adjust existing database schemas with sync capabilities).

The download contains a “Using Astoria Offline” document that gives a step-by-step walkthrough to create an offline-enabled application. The walkthrough provides an exploration of the infrastructure and how it can be used to build applications. Additionally, a complete example of an offline-enabled application is included in the download.

This release is built on top of the ADO.NET Data Services v1.0 release and .NET Framework 3.5 SP1. This is an early “preview” release, as such, it is not supported and should only be used for prototyping and investigating. As this is a preview release, it is strongly recommended that this release be installed in a test-only environment; a virtual machine is recommended. Please read the included README for more information on support and limitations of this download.

Note: This release is separate from the ADO.NET Data Services v1.5 CTP1 release that will be available soon. Installing this offline preview release on the same system as the v1.5 CTP1 is not supported and it is strongly recommended that you do not install the two releases on the same system.
