How to get Asp.Net Core to return the correct view

Question

My Asp.Net Core project is arranged as follows:

MyApp
--Folder1
  Folder1Controller.cs
  Index.cshtml
--Folder2
  Folder2Controller.cs
  Index.cshtml
--Views
  Shared
  etc..

I've changed the startup, so that it's aware of this directory structure:

services.Configure<RazorViewEngineOptions>(options =>
{
    options.ViewLocationFormats.Clear();
    options.ViewLocationFormats.Add($"/Folder1/{{0}}{RazorViewEngine.ViewExtension}");
    options.ViewLocationFormats.Add($"/Folder2/{{0}}{RazorViewEngine.ViewExtension}");
    options.ViewLocationFormats.Add($"/Views/Shared/{{0}}{RazorViewEngine.ViewExtension}");
});

The code for the Folder1Controller looks like this:

public IActionResult Index()
{            
    return View();
}

And it works fine. However, the code for Folder2Controller looks exactly the same. The problem is that when it executes the Index() method for Folder2 it looks in Folder1 first. I can get around it by doing this:

public IActionResult Index(string id)
{
    return View("/Folder2/Index.cshtml");
}

My question is, is there a way to get Asp.Net Core to look in the current directory first? Even if I use a relative path ( "./Index" ), it still goes to Folder1 first.

You can add a folder named with controller name to your folder1,folder2,so that route can recognize which view to find.

Firstly,change the folder structure like this:

MyApp
--Folder1
  Folder1Controller.cs
  --Folder1
    Index.cshtml
--Folder2
  Folder2Controller.cs
  --Folder2
    Index.cshtml
--Views
  Shared
  etc..

Startup:

  services.Configure<RazorViewEngineOptions>(options =>
                {
                    options.ViewLocationFormats.Clear();
                    options.ViewLocationFormats.Add("/Folder1/{1}/{0}" + RazorViewEngine.ViewExtension);
                    options.ViewLocationFormats.Add("/Folder2/{1}/{0}" + RazorViewEngine.ViewExtension);
                    options.ViewLocationFormats.Add($"/Views/Shared/{{0}}{RazorViewEngine.ViewExtension}");
                });

result:
