私はバックグラウンドで動作するアプリケーションを持っていますが、私はUWP APIでウィンドウを追加したかったのです。WPFアプリケーションでUWP UIを使用する
への参照を追加した後：
Windows.UI
Windows.UI.Xaml
私はUWPアプリケーションを起動しようとした：
using System;
using System.Diagnostics;
using Windows.ApplicationModel;
using Windows.ApplicationModel.Activation;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Navigation;
namespace ClipboardSync {
public class UWPApp : Windows.UI.Xaml.Application {
private bool _contentLoaded;
public void InitializeComponent() {
if (_contentLoaded)
return;
_contentLoaded = true;
}
public UWPApp() {
this.InitializeComponent();
this.Suspending += OnSuspending;
}
protected override void OnLaunched(LaunchActivatedEventArgs e) {
Frame rootFrame = Window.Current.Content as Frame;
// Do not repeat app initialization when the Window already has content,
// just ensure that the window is active
if (rootFrame == null) {
// Create a Frame to act as the navigation context and navigate to the first page
rootFrame = new Frame();
rootFrame.NavigationFailed += OnNavigationFailed;
if (e.PreviousExecutionState == ApplicationExecutionState.Terminated) {
//TODO: Load state from previously suspended application
}
// Place the frame in the current Window
Window.Current.Content = rootFrame;
}
if (e.PrelaunchActivated == false) {
if (rootFrame.Content == null) {
// When the navigation stack isn't restored navigate to the first page,
// configuring the new page by passing required information as a navigation
// parameter
rootFrame.Navigate(typeof(MainPage), e.Arguments);
}
// Ensure the current window is active
Window.Current.Activate();
}
}
/// <summary>
/// Invoked when Navigation to a certain page fails
/// </summary>
/// <param name="sender">The Frame which failed navigation</param>
/// <param name="e">Details about the navigation failure</param>
void OnNavigationFailed(object sender, NavigationFailedEventArgs e) {
throw new Exception("Failed to load Page " + e.SourcePageType.FullName);
}
/// <summary>
/// Invoked when application execution is being suspended. Application state is saved
/// without knowing whether the application will be terminated or resumed with the contents
/// of memory still intact.
/// </summary>
/// <param name="sender">The source of the suspend request.</param>
/// <param name="e">Details about the suspend request.</param>
private void OnSuspending(object sender, SuspendingEventArgs e) {
var deferral = e.SuspendingOperation.GetDeferral();
//TODO: Save application state and stop any background activity
deferral.Complete();
}
}
}
Windows.UI.Xaml.Application.Start(p => new UWPApp(););
ただし、新しいUWPAppインスタンスは作成されず、エラーメッセージも表示されません。
WPFアプリケーション内でUWPアプリケーションを開始できないような制限がありますか？
