EF 6 How to skip existing tables when generating migrations

Question

I am trying to use code-first within my existing project. I want to exclude existing entities from migrations I generate for new entities.

I have all models in separate class library project e.g. Data.Models and I am intending to use one context by creating another class library e.g. Infra.EF (model project is referenced in it).

This is how my DbContext looks like:

    public DbSet<ExistingEntityOne> DataOfEntityOne { get; set; }
    public DbSet<ExistingEntityTwo> DataofEntityTwo { get; set; }
    public DbSet<NewEntity> NewData { get; set; }

Sorry if question isn't clear but I can add more information based on your feedback.

Thanks.

Answer 1

1. Remove Migration directory from your project.

2. Comment new entities in your new DbContext.

   public DbSet<ExistingEntityOne> DataofEntityOne { get; set; }
   public DbSet<ExistingEntityTwo> DataofEntityTwo { get; set; }
   //public DbSet<NewEntity> NewData { get; set; }
   

3. Run following commands In power console manager:

   Enable-Migrations
   Add-Migration somename -IgnoreChanges
   

4. uncomment, commented entities.

   public DbSet<ExistingEntityOne> DataofEntityOne { get; set; }
   public DbSet<ExistingEntityTwo> DataofEntityTwo { get; set; }
   public DbSet<NewEntity> NewData { get; set; }
   

5. Run following command:

   Add-Migration someOtherName
