AppBar in UWP

Step 1: First of all we've to create a Blank Universal Windows Platform Project in Visual Studio 2015.

Step 2: The next thing we'll do is to add the following code.It should be kept in mind that the AppBar code goes after the Grid.

<Page.BottomAppBar>
    <CommandBar>
        <CommandBar.PrimaryCommands>
            <AppBarButton Name="webcamera" Icon="WebCam" Label="Camera" />
            <AppBarButton Name="user" Icon="AddFriend" Label="Add User" />

        </CommandBar.PrimaryCommands>

        <CommandBar.SecondaryCommands>
            <AppBarButton Name="webcamera" Icon="WebCam" Label="Camera" />
            </CommandBar.PrimaryCommands>
    </CommandBar>
</Page.BottomAppBar>

Notice that there're two types of commands Primary Command and Secondary Command.

Primary Command is for our buttons and secondary command is for Menu.

Following diagram makes the concept clear.
