Create a generic repository pattern-based class which exposes all the CRUD methods for handling a specific entity

public class Repository<T> : IRepository<T> where T : class
{
     private DbContext _context;
     private DbSet<T> _dbSet;

     public Repository()
     {
         _context = new DbContext();
         _dbSet = _context.Set<T>();
     }

     public void Delete(object id)
     {
         T entityToDelete = _dbSet.Find(id);
         Delete(entityToDelete);
     }

     public void Delete(T entityToDelete)
     {
         if (_context.Entry(entityToDelete).State == EntityState.Detached)
         {
             _dbSet.Attach(entityToDelete);
         }
         _dbSet.Remove(entityToDelete);
     }

     public IEnumerable<T> Get(Expression<Func<T, bool>> filter = null, Func<IQueryable<T>, IOrderedQueryable<T>> orderBy = null, string includeProperties = "")
     {
         IQueryable<T>
