I am using Entity Framework 4.1 and want to take advantage of their code-only approach. In the video located at http://channel9.msdn.com/Events/TechEd/Europe/2010/DEV212 starting at 35:00 minutes in they show a tool that reverse engineers their POCOs from their existing database. I want to do this as I have an existing database. I have installed EF 4.1 and I can create POCO entities just fine but I can't seem to find the tool they used to create POCOs from the existing database. Was this tool not released with 4.1?
Thanks in advance.
The tool is called EF Power Tools CTP1.
If your database is SQL Server, or SQL CE 4.0 then you can use the "Entity Framework Reverse POCO Generator" available at visualstudiogallery.msdn.microsoft.com
Update:
This answer is no longer relevant as EF 5+ is completely full-featured with code-first migration tools.
I had abandoned code-first for a while because it did not appear to be as full-featured as I had hoped. Recently I had some time to play with EF 4.1 a little more and examine it in more detail. All I really believe they are lacking now is a data/schema migration ability. This dropping and recreating of the database is not very ideal.
In my examination I found that the tool I am asking for in this question was indeed shipped with EF 4.1. It is a code generation template called "ADO.NET DbContext Generator". It can be found by opening up your existing EDMX file, right-clicking your design surface, and selecting "Add Code Generation Item".
