However as of now it is a little out of date with Nop version 3.8.
Ive followed the tutorial and made one change (the admin menu).
Im about to create the "CreateUpdatePromoSlider.cshtml" but im hit with an issue.
<li @Html.RenderSelectedTabIndex(0, GetSelectedTabIndex())>Slider</li>
Seems it doesnt contain a definition anymore.
Im guessing it was changed in 3.8, does any one know the fix for this?
