C# Entity Framework Database Migrations in Class Library

Question

I have a solution with an MVC 4 project and a class library. Both the MVC 4 project and the class library have database migrations enabled on them. I can run "Update-Database" for each project and apply both migrations to the database but when I try to add an addition migration to either project, the migration includes code to remove the tables from the other project's migrations. Any help on this would be appreciated.

Note: This is not a duplicate. This question is about migrations. My problem is that each set of migrations takes over the entire database.

Answer 1

Code first right?

i'm not sure if this will answer your question but you can try either of the following

• CreateDatabaseIfNotExists - this will only recreate the database if it does not exists
• DropCreateDatabaseAlways - this will always recreate the database, this will delete the current database including the data then recreate the database schema
• DropCreateDatabaseIfModelChanges - this will recreate the database if you change your model classes and will loose all the data.

hope that helps
