Summary

Install the latest version of the Entity Framework Power Tool
Restart Visual Studio.
On you Entities assembly:
right click and select Entity Framework/Customize Reverse Engineer Templates
* 3 templates will be added.
Save the project.
TO the model.tt template, add:
- virtual keyword to the properties to allow for POCO self-tracking
- Add WCF DataContract and DataMember to the properties
Right click on the Project and select Entity Framework/Reverse Engineer Code First

Note: For Enums, consider: http://linqto.net/blog/category/code-first/

Note: I could not get the namespace to taken into account right-clicking entities.tt and setting 'Custom Tool Namespace'. I tried several options that all caused exceptions:
