Name does not exist in namespace

Question

I am working on a simple UWP project using data template binding in VS 2015. When I try to specify the type for the Datatemplate, I get an error.

XAML:

<Page x:Name="RootPage"
x:Class="Adaptive_News_Layout.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
xmlns:local="using:Adaptive_News_Layout"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" FontSize="22" >

 <SplitView x:Name="MySplitView" Grid.Row="1" DisplayMode="CompactOverlay" Background="LightGray" OpenPaneLength="200"  >
            <SplitView.Pane>
                <ListView x:Name="MyListview" ItemsSource="{x:Bind NavigationItems}"  >
                    <ListView.ItemTemplate>
                        <DataTemplate x:DataType="local:NavItem" >
                            <StackPanel Orientation="Horizontal">
                                <RelativePanel>
                                    <Button x:Name="Icon"  FontFamily="Segoe MDL2 Assets" Content="{x:Bind ButtonIcon}" Width="50" Height="50"/>
                                    <TextBlock x:Name="Section" Text="{x:Bind SectionTitle}" RelativePanel.RightOf="Icon" />
                                </RelativePanel>
                            </StackPanel>
                        </DataTemplate>
                    </ListView.ItemTemplate>

This is the class:

namespace Adaptive_News_Layout
{
    public class NavItem
    {
        public string ButtonIcon { get; set; }
        public string SectionTitle { get; set; }
    }
}

The error is being read: The name "NavItem" does not exist in the namespace "using: Adaptive_News_Layout"

I realized what the problem is. This is a crash in Visual Studio 2015. After you add the namespace in XAML, it is best to compile / test your program or you will get this problem. The fix is ​​simple:
