namespace nancyapi
{
    public class ApiModule : Nancy.NancyModule
    {
        private ITaskRepository taskRepository;

        public ApiModule() {
            taskRepository = new TaskRepository();

            Get["/api"] = x => taskRepository.All;
            Get["/api/{id}"] = x => taskRepository.Find(x.id);
            Post["/api"] = pars =>
            {
                var task = new Task();
                task.Description = Request.Form.description;
                task.Priority = Request.Form.priority;
                task.CreatedOn = Request.Form.createdon;

                var id = taskRepository.InsertOrUpdate(task);
                taskRepository.Save();

                return JsonEncode(id);
            };
            Put["/api/{id}"] = pars =>
            {
                var task = new Task();
                task.Id = pars.id;
                task.Description = Request.Form.description;
                task.Priority = Request.Form.priority;
                task.CreatedOn = Request.Form.createdon;

                var id = taskRepository.InsertOrUpdate(task);
                taskRepository.Save();

                return JsonEncode(id);
            };
            Delete["/api/{id}"] = x => taskRepository.Delete(x.id);
        }
    }
}

In Nancy version, cant you just do this:

var task = this.Bind();
var id = taskRepository.InsertOrUpdate(task);
taskRepository.Save();

            return JsonEncode(id);

ok, but is there a performance difference?

It seems like you are doing way more error checking on the Web API version than the Nancy version, which un-fairly complicates the Web API code. If there is any automatic error handling that Nancy does, Web API could do the same to automatically turn un-handled exceptions into the proper responses.

Agree with @jrharmon. Even though this is 3 years old it is appearing in google searches. It is not a like for like comparison... should be updated to be more realistic.
