You have to use the NotifyIcon control from System.Windows.Forms, or alternatively you can use the Notify Icon API provided by Windows API. WPF Provides no such equivalent, and it has been requested on Microsoft Connect several times.

I have code on GitHub which uses <code>System.Windows.Forms</code> NotifyIcon Component from within a WPF application, the code can be viewed at <a href="https://github.com/wilson0x4d/Mubox/blob/master/Mubox.QuickLaunch/AppWindow.xaml.cs" rel="noreferrer">https://github.com/wilson0x4d/Mubox/blob/master/Mubox.QuickLaunch/AppWindow.xaml.cs</a>

Here are the summary bits:

Create a WPF Window with ShowInTaskbar=False, and which is loaded in a non-Visible State. 

At class-level:

<pre><code>private System.Windows.Forms.NotifyIcon notifyIcon = null;
</code></pre>

During OnInitialize():

<pre><code>notifyIcon = new System.Windows.Forms.NotifyIcon();
notifyIcon.Click += new EventHandler(notifyIcon_Click);
notifyIcon.DoubleClick += new EventHandler(notifyIcon_DoubleClick);
notifyIcon.Icon = IconHandles["QuickLaunch"];
</code></pre>

During OnLoaded():

<pre><code>notifyIcon.Visible = true;
</code></pre>

And for interaction (shown as notifyIcon.Click and DoubleClick above):

<pre><code>void notifyIcon_Click(object sender, EventArgs e)
{
 ShowQuickLaunchMenu();
}
</code></pre>

From here you can resume the use of WPF Controls and APIs such as context menus, pop-up windows, etc.

It's that simple. You don't exactly need a WPF Window to host to the component, it's just the most convenient way to introduce one into a WPF App (as a Window is generally the default entry point defined via App.xaml), likewise, you don't need a WPF Wrapper or 3rd party control, as the SWF component is guaranteed present in any .NET Framework installation which also has WPF support since it's part of the .NET Framework (which all current and future .NET Framework versions build upon.) To date, there is no indication from Microsoft that SWF support will be dropped from the .NET Framework anytime soon.

Hope that helps.

It's a little cheese that you have to use a pre-3.0 Framework Component to get a tray-icon, but understandably as Microsoft has explained it, there is no concept of a System Tray within the scope of WPF. WPF is a presentation technology, and Notification Icons are an Operating System (not a "Presentation") concept.

I am a total WPF newbie and wonder if anyone could give me some pointers how to write an application that starts minimized to tray. The idea is that it periodically fetches an RSS Feed and creates a Toaster-Popup when there are new feeds.

The Application should still have a Main Window (essentially just a list containing all feed entries), but that should be hidden by default.

I have started reading about XAML and WPF and I know that the StartupUri in the App.xaml has to point to my main window, but I have no idea what the proper way is to do the SysTray icon and hide the main window (this also means that when the user minimizes the window, it should minimize to tray, not to taskbar).

Any hints?

我是一个完全的WPF新手，不知道是否有人可以给我一些指针，如何编写一个应用程序，开始最小化到托盘。它的想法是定期获取一个RSS提要，并在有新提要时创建一个Toaster弹出窗口。应用程序应该仍然有一个主窗口(本质上只是一个包含所有提要条目的列表)，但在默认情况下，它应该是隐藏的。我已经开始阅读关于XAML和WPF的文章...
