Entity Framework code first: How to ignore classes

Question

This is similar to questions here and here, but those are old and have no good answers.

Let\'s say I have the following classes:

class HairCutStyle {         


        

Answer 1

There are three things to ensure:

1. Make sure you do not expose a DbSet in your DbContext-derived class
2. Make sure you do not have any mention of HairCutStyle in your OnModelCreating override
3. Mark your HairCutStyle property using the NotMapped attribute.
