ADO.Net Entity Framework Tools Aug 07 Community Technology Preview

The ADO.NET Entity Framework Tools Preview CTP contains a preview release of the ADO.NET Entity Designer which enables users to visually design model and mappings using Visual Studio 2008 Beta 2. The designer in this CTP has limited functionality and only supports a subset of the ADO.NET Entity Framework. Please refer to ReadMe.htm in the links below for a list of known issues in this CTP.

Overview of features in this CTP:

  Entity Designer  
* Generate a model from a database with the wizard and display it on the designer surface  

* Edit conceptual model properties (e.g. namespace, alias)  

* Layout and control visual aspects of the design surface and persist changes  

* Add, delete, and edit entities, scalar properties, associations, and inheritance  

* Automatic set management  

* Automatic navigation property management  

* Error reporting  

* Validate model and mappings using the Entity Framework Runtime  


  Entity Mapping  
* View the mapping for a C-Side Entity or Association  

* Rename or delete C-Side objects without worrying about mapping  

* Map an EntityType to multiple tables  

* Apply multiple conditions to a table mapping  

* Map associations  

* Automatic generation of conditions and referential constraints on associations  

* Map an Entity hierarchy to a single table (TPH mapping)  

* Map an Entity hierarchy to multiple tables (TPT mapping)  

  Entity Model Browser  
* Understand and visualize the model in a tree hierarchy  


  Visual Studio Integration  
* item template, model generation wizard, EdmxDeploy.exe, and Entity Framework validation on build
