The entity type <type> is not part of the model for the current context

julie asked 2 weeks ago

I am getting into the Entity Framework, but I am unsure if I am missing a critical point in the code-first approach.

I am using a generic repository pattern based on the code from and have created my entities.

But when I try to access or modify the entity I run into the following:

System.InvalidOperationException: The entity type Estate is not part
of the model for the current context.

It happens when I am trying to access it from my repository:

public virtual void Insert(TEntity entity)
    ((IObjectState)entity).ObjectState = ObjectState.Added;
    _dbSet.Attach(entity); // <-- The error occurs here

The database (./SQLEXPRESS) is created just fine, but the entities (tables) is just not created on startup.

I am wondering if I need to explicit set the mapping of the entities? Is EF not able to this by its own?

My Entity is:

public class Estate : EntityBase
    public int EstateId { get; set; }
    public string Name { get; set; }

My context is as so:

public partial class DimensionWebDbContext : DbContextBase // DbContextBase inherits DbContext
    public DimensionWebDbContext() :
        Database.SetInitializer<DimensionWebDbContext>(new CreateDatabaseIfNotExists<DimensionWebDbContext>());
        Configuration.ProxyCreationEnabled = false;

    public new IDbSet<T> Set<T>() where T : class
        return base.Set<T>();


Is there any specific reason why this error occurs? I have tried enable migrations and enable automatic migrations without any help either.
