I have the following

Controller/HomeController
Views/Home.cshtml and Home.aspx in same folder

Now when this below code executes;

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

Controller fetches Home.aspx first not Home.cshtml.

Any reason ? Why does it select aspx over cshtml ?

What I have tried:

I tried the code and i understood that it first fetches aspx but i want to know WHY ?

That depends on the view engine.
If you are using the Razor view engine, it will choose .cshml over .aspx.

If you're using web forms, then it will choose .aspx (or .ascx for partial views) over .cshtml.

By default, it looks like the "web forms" view engine is registered before the Razor view engine:
aspnetwebstack/ViewEngines.cs[^]

C#

private static readonly ViewEngineCollection _engines = new ViewEngineCollection
{
    new WebFormViewEngine(),
    new RazorViewEngine(),
};

If you don't need aspx views, you can remove the WebFormViewEngine in the Application_Start event:

C#

var webFormEngine = ViewEngines.Engines.OfType<WebFormViewEngine>().FirstOrDefault();
if (webFormEngine != null) ViewEngines.Engines.Remove(webFormEngine);

If you want both view engines, but want Razor views to take priority, you can change the order:

C#

ViewEngines.Engines.Clear();
ViewEngines.Engines.Add(new RazorViewEngine());
ViewEngines.Engines.Add(new WebFormViewEngine());
