I have an MVC 5 application, made from the empty template. I've added Microsoft.AspNet.Mvc via Nuget and my packages file looks like so:
<packages>
<package id="Microsoft.AspNet.Mvc" version="5.2.3" targetFramework="net46" />
<package id="Microsoft.AspNet.Razor" version="3.2.3" targetFramework="net46" />
<package id="Microsoft.AspNet.WebPages" version="3.2.3" targetFramework="net46" />
<package id="Microsoft.CodeDom.Providers.DotNetCompilerPlatform" version="1.0.0" targetFramework="net46" />
<package id="Microsoft.Net.Compilers" version="1.0.0" targetFramework="net46" developmentDependency="true" />
<package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net46" />
</packages>
I have a Razor page that declares a model with @model IEnumerable<Models.ToDoModel> and uses it in a foreach loop.
@model IEnumerable<Models.ToDoModel>
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Home</title>
</head>
<body>
<h1>Hello World!</h1>
<ul>
@foreach (var item in Model)
{
<li>ID: @item.Id</li>
}
</ul>
</body>
</html>
When I run the page, it renders fine, however Visual Studio persistently said there's an error:
It won't recognise the model keyword or give me any Intellisense.
My Web.Config looks like so:
<?xml version="1.0" encoding="utf-8"?>

I encountered this issue and tried every solution under the sun. For a week I tried editing the web config (in both the view and the root), reloading the project, clearing resharper caches.. you name it, I tried it. I loaded up an old project and hovered over the "Layout" and "Model" sections to see what namespaces they required. On closer examination, the namespaces which were required had been removed from my project. I have no idea how - I had recently performed an upgrade.. Anyhow - I referenced these 2 files from the solution folder System.Web.Mvc and another, rebuilt, and it worked. I could have danced on the spot. Hope this helps someone down the line!

If you have resharper , suspending it will fix i.e: Tool - Options - Resharper - Suspend
