ASP.NET MVC with AngularJS

Question

I have been doing with ngRoute. I've SPA which having 2 tabs clicking on each tab we show partial as html, but I'm experiencing issue while navigating from one tab to another tab when use like below.

angular.module('sam').config(function($routeProvider){
    $routeProvider.when('/main/customer',{
             templateUrl:"customer.html",
             controller:"customerController"
      })
    .when('/main/client',{
             templateUrl:"client.html",
            controller:"clientController"
      });
});

the above line kept it as separate file called app.js, Here I use ASP.NET MVC as backend, so from index.cshtml I did like below

<a href="/main/customer">Customer</a>
<a href="/main/client">Client</a>

I am experiencing an issue with above coding. But in angular ngRoute the second / looks for routeParams???that's why I'm getting error??

Can anyone help me in this.
