namespace ConsoleAppExample
{
    public class Program
    {
        public static void Main(string[] args)
        {
            // You should build a DbContextOptions for CasbinDbContext<TKey>.
            // The example use the SQLite database named "casbin_example.sqlite3".
            var options = new DbContextOptionsBuilder<CasbinDbContext<int>>()
                .UseSqlite("Data Source=casbin_example.sqlite3")
                .Options;
            var context = new CasbinDbContext<int>(options);

            // If it doesn't exist, you can use this to create it automatically.
            context.Database.EnsureCreated();

            // Initialize a EF Core adapter and use it in a Casbin enforcer:
            var efCoreAdapter = new EFCoreAdapter<int>(context);
            var e = new Enforcer("examples/rbac_model.conf", efCoreAdapter);

            // Load the policy from DB.

            e.Enforce("alice", "data1", "read");
            
            // Modify the policy.
            // e.AddPolicy(...)
            // e.RemovePolicy(...)
