Entity Framework entity can't be found in dbcontext auto-generated code

Question

I use entity framework 6.1.3 model first approach. I needed to design a simple model as following.

Then i generated sql to create the database but i found that my entities sets were not defined in my DbContext. I tried to add them manually but Entity Framework keeps regenerating the following code. It only generates the abstract entity which is exactly the opposite of what it is designed for.

public partial class UploadsDataModelContainer : DbContext
{
    public UploadsDataModelContainer()
        : base("name=UploadsDataModelContainer")
    {
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        throw new UnintentionalCodeFirstException();
    }
    public virtual DbSet<AzureBlobs> AzureBlobs { get; set; }
}

Is this a bug in EF code generator or am i missing a step in model creation ?

You probably want to map both subtypes to their own tables. See TPH vs. TPT or TPC inheritance. And add an entity set name in the designer. — Gert Arnold

If you want, because Visual Studio generates partial classes, you can add a new file with the same UploadsDataModelContainer context and add the relevant properties: public DbSet<Upload> Uploads { get; set; } — Ricardo Peres

Thanks to RicardoPeres i added a class file with the following content and it resolved my problem by avoiding the automatic updates of the DbContext.cs file :

    public partial class UploadsDataModelContainer : DbContext
{

    public virtual DbSet<Chunk> CHunks { get; set; }
    public virtual DbSet<Upload> Uploads { get; set; }

}
