WPF integration

1. Application startup

Call bootstrap before showing the main window so staged updates and JSON settings load exactly like WinForms.

using System.Windows;
using LicenPro.SDK.AppHosting;

public partial class App : Application
{
    protected override void OnStartup(StartupEventArgs e)
    {
        SdkBootstrap.OnApplicationStartup();
        base.OnStartup(e);
    }
}

2. Async validation without blocking the UI thread

Construct LicenseClient on a background thread or the UI thread, but always await validation. LicenseClient captures SynchronizationContext.Current when created; expiry warnings (LicenseExpiringSoon) are posted back to that context, so constructing the client on the UI thread keeps dialogs safe.

3. MVVM-oriented layering

Recommended shape:

• ILicenseService (your interface) wraps LicenseClient, exposes Task-based validate / try-auto-validate, and forwards SessionDisconnected.
• App-level host owns service lifetime and calls DisposeAsync on shutdown.
• View models bind commands to the service; never block the UI thread with synchronous validation APIs.

4. Hardware identity

The SDK computes a composite hardware fingerprint internally for activation and update checks. You normally do not need a separate “WPF hardware provider”; only supply IHardwareIdentifier in advanced test scenarios.
