Splitting EDMX Model

Question

I'm looking to split my EDMX models into their own project to be referenced across the different projects without having to recreate the models across projects.

I have one project that contains the Entity Data Model. I have another project that will contain common items across the projects. This common project, I would like it to contain the Entity Models and remove them from the Entity Data Model project.

In the common project, I add an EF dbContext Generator. I change the .tt inputFile to point to the edmx file in the other project and remove the .tt file from the Entity Data Model project.

This works but how do I go about handling any changes to the Entity Data Model and carrying them over to the common project since the .tt file no longer exists?

Is there a better solution for this?

Answer 1

I figured it out. All I need to do is right click on the .tt file in the common model and choose 'Run Custom Tool'
