Configuring view and area locations

In this recipe, you will learn how to change the view location used per convention by ASP.NET Core MVC.

Getting ready

We will use the previous recipe and add some modifications to use a different view location.

How to do it...

1. First, let's create a new views folder named ViewsOld. In this folder, we will copy _ViewImports.cshtml and _ViewSart/cshtml from the Views folder, and cut the Product views folder to paste it into the ViewsOld folder:

2. Next, we create a folder named Infrastructure and create a C# class named OldViewsExpander.cs. This class will contain the following code:

public class OldViewsExpander : IViewLocationExpander
{
  public IEnumerable<string> ExpandViewLocations
  (ViewLocationExpanderContext context,
  IEnumerable<string> viewLocations)
  {
    // rerturn all classic locations
    foreach (string location in viewLocations)
    {
      yield return location;
    }
    // return new locations
    yield return "/ViewsOld/Shared/...
