asp.net-core-mvc Change default view location Create a View Location Expander

Example

To be able to change the view location, you need to implement the IViewLocationExpander. The ExpandViewLocations method returns an IEnumerable<string> containing the different locations where to search, with

public class MyViewLocationExpander : IViewLocationExpander
{
    public IEnumerable<string> ExpandViewLocations(ViewLocationExpanderContext context, IEnumerable<string> viewLocations)
    {
        yield return "/CustomViewFolder/{1}/{0}.cshtml";
        yield return "/SharedFolder/{0}.cshtml";
    }

    public void PopulateValues(ViewLocationExpanderContext context)
    {            
    }
}
