using a locally published web app

[EDIT by guardrex to fix the code blocks]

### Description

Your document is hard to follow.

The following code does not work:

```csharp
public class ProductsController : Controller
{
public IActionResult Details(int id)
{
return ControllerContext.MyDisplayRouteInfo(id);
}
}
```

I get a CS1061 error.

I have added the package to the project's csproj file:

```xml

net8.0
enable
enable

```
