How to set Default Controller in asp.net MVC 4 & MVC 5

the best way is to change your route. The default route (defined in your App_Start) sets /Home/Index

routes.MapRoute(        "Default", // Route name        "{controller}/{action}/{id}", // URL with parameters*        new { controller = "Home", action = "Index",         id = UrlParameter.Optional });

as the default landing page. You can change that to be any route you wish.

routes.MapRoute(        "Default", // Route name        "{controller}/{action}/{id}", // URL with parameters*        new { controller = "Sales", action = "ProjectionReport",         id = UrlParameter.Optional });

Set below code in RouteConfig.cs in App_Start folder

public static void RegisterRoutes(RouteCollection routes){ routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( name: "Default", url: "{controller}/{action}/{id}", defaults: new { controller = "Account", action = "Login", id = UrlParameter.Optional });}

IF still not working then do below steps

Second Way : You simple follow below steps,

1) Right click on your Project

2) Select Properties

3) Select Web option and then Select Specific Page (Controller/View) and then set your login page

Here, Account is my controller and Login is my action method (saved in Account Controller)

Please take a look attached screenshot.

I didnt see this question answered:

How should I setup a default Area when the application starts?

So, here is how you can set up a default Area:

var route = routes.MapRoute(    name: "Default",    url: "{controller}/{action}/{id}",    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }    ).DataTokens = new RouteValueDictionary(new { area = "MyArea" });
