The most obvious choice is to select “Run Custom Tool” from the EDMX file, but that doesn’t do anything: If you F4 the corresponding T4 file you can see that the custom tool associated with the T4 file is: Text Templating File Generator So, I selected “Run Custom Tool” from the T4 context menu: And that generated the file: But I still didn’t have the Foo class in my object model: So I selected the “Run Custom Tool” on the “Conf Speakers. I will ping the product team to see if they can run the custom tool on the EDMX file when it is saved and recursively run on all the tt files associated with that EDMX parent.Context.tt” file: And that generated the correct object model: So anytime you find your EF model and/or class files out of sync with your database then you need to manually run the “Run Custom Tool” command on both the [Entities]file and the [Entities].

Be very careful when deleting or renaming primary and foreign keys columns. Existing properties and associations will become unmapped and new key properties will appear.

This is particularly important when renaming or deleting database objects that you have previously mapped to your EDM.

The wizard's guiding principal is that the conceptual entity model is yours.

The procedure in this topic describes how to generate an file that is based on an existing database and how to generate an empty file.

When I have a table with the columns ID, Column1, Column2 and I changed Column2 into Column2Changed, my edmx has a model with ID, Column1, Column2, Column2Changed instead of ID, Column1, Column2Changed.

That's why it only adds to the conceptual entity model; it won't remove or change anything in the conceptual model.

However, the wizard acts as if it owns the storage and mapping schemas.You should assume that the wizard rewrites everything in the mapping and storage schemas.Of course it reads your previous mappings and preserves them if it understands them.An entity that once had a single part key will have a composite two part key: the old key property under the old name and the new key property under the new name property.This change cascades to the associations that depend upon that key.You will have to make manual repairs when you delete or rename anything in the database. You can power through it if you know what changed in the database and remember that the wizard only adds, never deletes.
