Question

Unable to create an object of type \'My

Answer 1

The quick solution to the problem is to implement the default constructor in your context

 public MyContext() : base()
 {
 }

The problem with this solution is that you will have to enter the connection string in the 'OnConfiguring' function explicitly, which is not recommended

 protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
 {
        if (!optionsBuilder.IsConfigured)
        {
            optionsBuilder.UseSqlite("ConnectionString");
        }
 }
