I have a project on Sitecore 9.3 that uses both View and Controller renderings. My view renderings have not had any intellisense errors so far and work just fine after being built.
When I built my first Controller Rendering, I got the error "The type or namespace name 'AspNetCore' does not exist in the namespace 'Microsoft'. If I add a package reference to AspNetCore v2.2.0, the intellisense errors on my Controller Rendering are fixed; however, now I see intellisense errors on all of my View Renderings.
The error on my View Renderings is "'IHtmlHelper' does not contain a definition for 'Sitecore' and the best extension method overload 'HtmlHelperExtensions.Sitecore(HtmlHelper)' requires a receiver of type 'HtmlHelper'".
I have verified that I am using the correct version of System.Web.Mvc (5.2.4) and all references in the web.config files in the views folders are the correct version. I also verified that the version of System.Web.Mvc.dll is the same in my web root.

I also tried adding a package reference to Microsoft.AspNet.Mvc (5.2.4) but that did not fix the problem.
I have verified that the version of the web.config file in the views folder in the web root is the same as the version in my project. All web.config files in my project have their build action set to none and copy to output directory set to do not copy so the web root is never overridden.
I am using the Sitecore Helix Templates VS Extension (if that makes a difference). If I publish the solution as-is with the intellisense errors, it makes no difference and my code works just fine when rendered on the live site. But, I would very much like to remove all intellisense errors from my solution. Thank you in advance for your help!
Edit: Adding Controller Code
using Sitecon.Feature.PageContent.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web.Mvc;
namespace Sitecon.Feature.PageContent.Controllers
{
public class PageContentController : Controller
{
public ActionResult ListWithIcons()
{
if (Sitecore.Context.Item == null)
{
return new EmptyResult();
}
var item = Sitecore.Context.Item;
var multiLineTextString = item.Fields[Templates.ListWithIcons.Fields.ListText].Value;
ListWithIconsItems listWithIconsItems = new ListWithIconsItems();
listWithIconsItems.ListItems = new List<string>();
if (string.IsNullOrEmpty(multiLineTextString))
{
return new EmptyResult();
}
string[] sep = new string[] { "\r\n" };
string[] lines = multiLineTextString.Split(sep, StringSplitOptions.RemoveEmptyEntries);
foreach (string listItem in lines)
{
if (!string.IsNullOrEmpty(listItem))
{
listWithIconsItems.ListItems.Add(listItem);
}
}
listWithIconsItems.ListIcon = item.Fields[Templates.ListWithIcons.Fields.ListIcon].Value;
return View(listWithIconsItems);
}
}
}
Model Code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Sitecon.Feature.PageContent.Models
{
public class ListWithIconsItems
{
public string ListIcon { get; set; }
public List<string> ListItems { get; set; }
}
}
Controller Rendering Code:
@using Sitecore.Mvc
@using Sitecore.Mvc.Presentation
@using Sitecon.Feature.PageContent.Models
@using Sitecon.Foundation.SitecoreHelperExtensions
@model ListWithIconsItems
<ul class="fa-ul">
@foreach (var li in Model.ListItems)
{
<li><span class="fa-li"><i class="fas [email protected]"></i></span>@li</li>
}
</ul>
Intellisense is erroring on Model.ListItems & Model.ListIcon: The name 'Model' does not exist in the current context
