ASP.NET Core MVC & Controller Integration

If you aren't using Minimal APIs yet, Sannr still tightly integrates into standard ControllerBase architectures.

The Sannr setup automatically installs an IObjectModelValidator designed natively to override standard reflection behaviors completely, while correctly populating ModelState entries intuitively.

var builder = WebApplication.CreateBuilder(args);

// Replaces standard metadata constraints automatically
builder.Services.AddControllers();
builder.Services.AddSannr();

var app = builder.Build();

Creating the Controller

Validation runs the exact same way you expect. Because Sannr's IObjectModelValidator intercepts the binder, your controllers gracefully receive pre-validated objects or explicitly bound ModelState hierarchies without custom action filters.

using Microsoft.AspNetCore.Mvc;

[ApiController]
[Route("[controller]")]
public class UserController : ControllerBase
{
    [HttpPost]
    public IActionResult CreateUser([FromBody] UserRegistration model)
    {
        // Executes exactly like standard DataAnnotationsbut 20x faster.
        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        // Processing...
        return Ok(model);
    }
}

AOT Compatibility Notes

Be aware that AddControllers() itself breaks Native AOT guidelines natively inside extensive metadata trees without aggressive explicit route configurations. If you demand absolute .NET 8 Native AOT capabilities, we strongly advise evaluating our Minimal API patterns instead.
