Ola, I am trying to put in ifs layout in order to change login to logout but it is not working. In Layout I have this code : 

@using Microsoft.AspNetCore.Http;
@using WebApplication1.Controllers;
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>@ViewData["Title"] - WebApplication1</title>
<link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.min.css" />
<link rel="stylesheet" href="~/css/site.css" />
<link href="~/lib/jqueryui/jquery-ui.css" rel="stylesheet" />
</head>
<body>
<header>
    <nav class="navbar navbar-expand-sm navbar-toggleable-sm navbar-dark bg-dark border-bottom box-shadow mb-3">
        <div class="container">

                    aria-expanded="false" aria-label="Toggle navigation">

            </button>
            <div class="navbar-collapse collapse d-sm-inline-flex flex-sm-row-reverse">

It is necessary to change @else if for else if.

Ex: https://www.w3schools.com/asp/showfile_c.asp?filename=try_razor_cs_012

@{var price=25;}
<html>
<body>
@if (price>=30)
    {
    <p>The price is high.</p>
    }
    else if (price>20 && price<30) 
    {
    <p>The price is OK.</p>
    }
    else
    {
    <p>The price is low.</p>
    }
</body>
</html>
