producesresponsetype attribute in C#

In C#, the producesresponsetype attribute is used to specify the MIME types or content types that a
web API action method can produce as a response. It enables the API to inform the client about the type of data it
can expect in the response.

Example:


[ApiController]
[Route("api/[controller]")]
public class UsersController : ControllerBase
{
    [HttpGet]
    [Produces("application/json")] // Specify the content type as JSON
    public ActionResult<User> GetUser()
    {
        User user = GetUserFromDatabase();
        if (user == null)
        {
            return NotFound("User not found");
        }
        return user;
    }
    
    // Other action methods...
}

In the above example, the [Produces("application/json")] attribute is applied to the GetUser
action method in the UsersController class. It indicates that this method will produce JSON as its response
type. This helps API consumers to understand that they will receive JSON data when invoking this action.

The [ApiController] attribute is used to enable automatic model validation and binding source inference
in the controller. The [Route("api/[controller]")] attribute specifies the routing pattern for the API
controller.
