Use this generator to create a page-mapping dictionary class for JsonNavigationService, and configure it by calling NavService.Initialize(NavView, NavFrame, NavigationPageMappings.PageDictionary).

This generator reads the JSON file and extracts each UniqueId along with its corresponding page type.

How To Use it?

Just add an AdditionalFiles entry to your .csproj.

<ItemGroup>
  <AdditionalFiles Include="Assets\NavViewMenu\AppData.json" Link="%(RecursiveDir)%(Filename)%(Extension)" Visible="false"/>
</ItemGroup>

Namespace

You can define your own namespace by adding a property to a PropertyGroup.

<PropertyGroup>
    <NavigationMappingsNamespace>MyNavigationMappingsNamespace</NavigationMappingsNamespace>
</PropertyGroup>

Result

The result is a mapping dictionary similar to the following:

public partial class NavigationPageMappings
{
    public static Dictionary<string, Type> PageDictionary { get; } = new Dictionary<string, Type>
    {
        {"DevWinUIGallery.Views.HomeLandingPage", typeof(DevWinUIGallery.Views.HomeLandingPage)},
        {"DevWinUIGallery.Views.ColorAnalyzerPage", typeof(DevWinUIGallery.Views.ColorAnalyzerPage)},
        {"DevWinUIGallery.Views.MenuFlyoutSecondaryMenuPage", typeof(DevWinUIGallery.Views.MenuFlyoutSecondaryMenuPage)},
    }
}

NOTE

Each valid JSON file generates its own mapping class. A single file keeps the NavigationPageMappings name; with multiple files, AppData.json (or the first file by path if absent) generates NavigationPageMappings, while other files use their filename as a suffix (for example, AppDataGlyph.json generates NavigationPageMappingsAppDataGlyph).
