Microsoft SQL Server Compact 3.5 SP1 Beta for ADO.Net Entity Framework Beta 3

SQL Server Compact 3.5 SP1 Beta release for the ADO.Net Entity Framework Beta 3 enables the following scenarios:

Applications can work in terms of a more application-centric conceptual model, including types with inheritance, complex members, and relationships
Applications are freed from hard-coded dependencies on a particular data engine or storage schema
Mappings between the conceptual application model and the storage-specific schema can change without changing the application code
Developers can work with a consistent application object model that can be mapped to various storage schemas, possibly implemented in different database management systems
Multiple application models can be mapped to a single storage schema
Language-integrated query support provides compile-time syntax validation for queries against a conceptual model
