Inject DbContextOptions vs DbContext in a repository EF Core

Question

I have the StudentDbContext

public class StudentDbContext : DbContext
{
    public StudentDbContext()
    {
    }

    public StudentDbContext(DbContextOptions<StudentDbContext> options)
        : base(options)
    {

    }

    public virtual DbSet<Students> Students{ get; set; }

}

and then I have a repository and I try to understand what is the difference if I inject the StudentDbContext vs inject DbContextOptions

Inject the DbContextOptions

class StudentRepository : IStudentRepository
{
    private readonly DbContextOptions<StudentDbContext> _context;

    public StudentRepository(DbContextOptions<StudentDbContext> context)
    {
        _context = context;
    }
}

Inject StudentDbContext

class StudentRepository : IStudentRepository
{
    private readonly StudentDbContext _context;

    public StudentRepository(StudentDbContext context)
    {
        _context = context;
    }
}

Are there any advantages or disadvantages in each case?

Answer 1

DbContextOptions class is used to create the options to be used by a DbContext. It configures the database (and other options) to be used for the database context. DbContext class contains DbSet properties for each entity in the model. If you try to use DbContextOptions in a repository you will have no access to any model since it doesn't have them.
