I am using Entity Framework 4.1 and want to take advantage of their code-only

  • 0

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.

    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”.
