I have done it.

<pre lang="c#">
public class wishlistController : ApiController
    {
        DataContext rdb;
        public wishlistController()
        {
            rdb = new DataContext();
            rdb.Configuration.ProxyCreationEnabled = false;
        }
        ~wishlistController()
        {
            rdb.Dispose();
        }


        public List<wishlist> Delete(int wishid = 0)
        {

            //List<wishlist> deletwish = new List<wishlist>();
           var deletwish =rdb.wishlists.Single(x => x.WishID == wishid);
           rdb.wishlists.Remove(deletwish);
           rdb.SaveChanges();
           return rdb.wishlists.ToList();
        }

    }
</pre>
