Quick Start

Show Registration Dialog

using LicenseManagement.EndUser.Wpf.Views;
using LicenseManagement.EndUser.Wpf.ViewModels;

var viewModel = new RegisterLicenseViewModel();
var view = new RegisterLicenseView
{
    DataContext = viewModel
};

if (view.ShowDialog() == true)
{
    string receiptCode = viewModel.ReceiptCode;
    // Process the receipt code
}

Display License Status

using LicenseManagement.EndUser.Wpf.ViewModels;

var licenseVm = new LicenseViewModel
{
    Status = LicenseStatusTitles.Valid,
    ExpirationDate = DateTime.UtcNow.AddMonths(6),
    ProductName = "My Product"
};

Use Converters in XAML

<Window xmlns:converters="clr-namespace:LicenseManagement.EndUser.Wpf.Converters.ValueConverters;assembly=LicenseManagement.EndUser.Wpf">
    <Window.Resources>
        <converters:LicenseStatusConverter x:Key="StatusConverter"/>
        <converters:UtcToLocalTimeConverter x:Key="TimeConverter"/>
    </Window.Resources>

    <TextBlock Text="{Binding Status, Converter={StaticResource StatusConverter}}"/>
    <TextBlock Text="{Binding ExpirationDate, Converter={StaticResource TimeConverter}}"/>
</Window>

Include Resource Dictionary

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/LicenseManagement.EndUser.Wpf;component/AppResources.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

Sample Application

We provide a complete sample WPF application demonstrating real-world usage patterns:

WPF Sample App

The WPF Sample Application demonstrates:

• License validation at application startup
• Handling different license states (Valid, Trial, Expired)
• Feature gating based on license status
• Integration with built-in license management UI
• Centralized license service pattern

// Example: Validate license at startup
private void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
    var context = _licenseService.ValidateLicense(
        onLicFileNotFound: DownloadLicenseFile,
        onTrialEnded: HandleTrialEnded
    );
    UpdateFeatureAccess(context.LicenseModel.Status);
}

See the sample README for complete setup instructions.
