Answer 1

Your problem is the ApplicationDbContext is not a module it's the class name of the contractor. So replace the ApplicationDbContext with ProjectDbContext. and your problem with be solved.

Here is the code you:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.EntityFrameworkCore;

namespace Rocky.Data
{
public class ProjectDbContext:DbContext
{
    public ProjectDbContext(DbContextOptions<ProjectDbContext> options): base(options)
    {

    }
}
}
