If we run our project in debug mode, we can see that our code changes don't prevent the client app from booting properly. We didn't break it this time, yay! However, if we try to use the navigation menu to go to the Counter and/or Fetch data, nothing will happen; this is hardly a surprise, since we just moved these components out of the way. To avoid confusion, let's remove these links from the menu as well.

Open the /ClientApp/app/components/navmenu/navmenu.component.html file and delete the offending lines. Once done, the updated source code should look as follows:

<div class='main-nav'>
    <div class='navbar navbar-inverse'>
        <div class='navbar-header'>
            <button type='button' class='navbar-toggle' data-   
              toggle='collapse' data-target='.navbar-collapse'>
                <span class='sr-only'>Toggle navigation</span>
                <span class='icon-bar'></span>
                <span class='icon-bar'></span>
                <span class='icon-bar'></span>
            </button>
            <a class='navbar-brand' [routerLink]=" 
            ['/home']">TestMakerFree</a>
        </div>
        <div class='clearfix'></div>
        <div class='navbar-collapse collapse'>
            <ul class='nav navbar-nav'>
                <li [routerLinkActive]="['link-active']">
                    <a [routerLink]="['/home']">
                        <span class='glyphicon glyphicon-home'></span>       
                          Home
                    </a>
                </li>
            </ul>
        </div>
    </div>
</div>

While we're here, let's take the chance to get rid of something else. Do you remember the Hello, World! introductory text shown by the browser when we firstly ran the project? Let's change it with our own content.

Open the /ClientApp/app/components/home/home.component.html file and replace its whole content with the following:

<h1>Greetings, stranger!</h1>
<p>This is what you get for messing up with .NET Core and Angular.</p>

Save, run the project in debug mode and get ready to see the following:

The Counter and Fetch data menu links are gone, and our Home View welcome text couldn't be sleeker.

That's about it for now. Rest assured, we can easily do the same with other components and completely rewrite their text, including the navigation menu; we'll do that in the following chapters, where we'll also update the UI layout, add new components, and so on. For the time being, understanding how easy it is to change the content--and also how fast Webpack will handle our modifications--is good enough.
