        [HttpPost]

        {
            try
            {

                return Redirect("~/Home");
            }
        }
    }
}

• Step 2:Now Lets modify Index.cshtml with the following

@{
    Layout = null;
}
@using Microsoft.AspNet.Identity
<!DOCTYPE html>
<html>
<head>
    <meta name="HandheldFriendly" content="true" />
    <meta name="viewport" content="width=device-width,
          initial-scale=1, minimum-scale=1, maximum-scale=1, user-scalable=no" />
    <title>Log In</title>
</head>
<body>
    <div>
        @if (Request.IsAuthenticated)
        {
            using (Html.BeginForm("LogOut", "Account",
                FormMethod.Post, new { id = "logoutForm", @class = "navbar-right" }))
            {
                @Html.AntiForgeryToken()
                <p>
                    Hello @User.Identity.GetUserName() |
                    @Html.ActionLink("Change Password",
                    "ChangePassword", "Account",
                    routeValues: null, htmlAttributes: new { id = "changepassword" }) |
                    <a href="javascript:document.getElementById('logoutForm').submit()">Log off</a>
                </p>
                <a href="HTMLClient">LightSwitch Application</a>
            }
        }
        else
        {
            <p>
                @Html.ActionLink("Register", "Register", "Account",
                routeValues: null, htmlAttributes: new { id = "registerLink" }) |
                @Html.ActionLink("Log in", "Login", "Account",
                routeValues: null, htmlAttributes: new { id = "loginLink" })
            </p>
        }
    </div>
</body>
</html>
