Error when creating controller in Episerver

Question

I'm trying to create a block in Episerver but got an error for the name of my class in the controller. The errormessage is

The type 'MyEpiserverSite.Controllers.WeekletterController' cannot be used as type parameter 'TBlockData' in the generic type or method 'BlockController'. There is no implicit reference conversion from 'MyEpiserverSite.Controllers.WeekletterController' to'EPIServer.Core.BlockData'

My code is

using EPiServer.Web.Mvc;
using EpiserverSite1.Models.Blocks;
using System.Web.Mvc;

namespace MyEpiserverSite.Controllers
{
    public class WeekletterController : BlockController<WeekletterController>
 {
    public override ActionResult Index(WeekletterBlock currentblock)
    {
        return PartialView(currentblock);
    }
 }
}

Is there any using that I am missing or what are wrong whit my code?

Answer 1

You inherit from BlockController<WeekletterController> but you should inherit from BlockController<WeekletterBlock>.
