Entity Framework in one project but on 2 solutions

Hi

I have an entity framework project in my solution which is a CMS, and I also have a solution which uses the same project, using Add Exisiting Project.

Everything works fine on the CMS project, but when I do an update it always breaks the other project due to:

The model backing the 'ApplicationDbContext' context has changed since the database was created. Consider using Code First Migrations to update the database (http://go.microsoft.com/fwlink/?LinkId=238269).

Is there a way to fix it, so when i run the other solution it doesn't bring up the error?
