        public ToDosController(IToDoService _service)
        {
            service = _service;

        [HttpPost]

Service >

    public class ToDoService : IToDoService
      {
        IToDoFW database;

        public ToDoService(IToDoFW _database)
        {
            this.database = _database;
        }
        public void Add(ToDo toDo)
        {
            database.Add(toDo);
        }
      }

This is my program.cs codes:

    var builder = WebApplication.CreateBuilder(args);
 
    // Add services to the container.
    builder.Services.AddControllers();

    // Learn more about configuring Swagger/OpenAPI at 
    https://aka.ms/aspnetcore/swashbuckle
    builder.Services.AddEndpointsApiExplorer();
    builder.Services.AddSwaggerGen();

    builder.Services.AddDbContext<ToDoContext>();
    var app = builder.Build();

    // Configure the HTTP request pipeline.
    if (app.Environment.IsDevelopment())
    {
      app.UseSwagger();
      app.UseSwaggerUI();
    }
    IServiceCollection services;
    app.UseHttpsRedirection();

    app.UseAuthorization();

    app.MapControllers();

    app.Run();

Fw it means that FrameWork. . . . I hope you can help me about it, thanks for reading guys

You have to add the service to your IServiceCollection in your Program.cs (for .NET6 and higher) or Startup.cs (.NET 5.0 and lower).

services.AddScoped<IToDoService, ToDoService>();
