Note

Windows in project references is for using Windows Runtime (WinRT) API. It refers to Windows.winmd whose location has been changed over time. If it is not solved, find its location in your system and modify its path in .csproj file.

Usage

Instantiate ToastRequest class, set its properties and then call ToastManager.ShowAsync method.

public async Task<bool> ShowToastAsync()
{
    var request = new ToastRequest
    {
        ToastTitle = "DesktopToast WPF Sample",
        ToastBody = "This is a toast test.",
        ToastLogoFilePath = string.Format("file:///{0}", Path.GetFullPath("toast128.png")),
        ShortcutFileName = "DesktopToast.Wpf.lnk",
        ShortcutTargetFilePath = Assembly.GetExecutingAssembly().Location,
        AppId = "DesktopToast.Wpf",
    };

    var result = await ToastManager.ShowAsync(request);

    return (result == ToastResult.Activated);
}

Action Center of Windows 10

To interact with Action Center of Windows 10, an application needs to register COM class type which implements INotificationActivationCallback. In addition, the registration of COM server in the registry is required for an application to be started by COM when it is not running.

See WPF sample for implementation. Note that the CLSID of COM class type (AppUserModelToastActivatorCLSID) must be unique for each application.
