Change taskbar icon at runtime on deployed app

I would like to change taskbar icon to identity what type the current app is, so I set a default icon for the app and the icon will be changed according to the type returned from server when the app is launching.

I just change the icon like this:

```csharp
Application.Current.MainWindow.Icon = new BitmapImage(new Uri(string.Format("AppLogos/{0}.ico", terminal.TerminalType.Name), UriKind.Relative));
```

It's working well on Visual Studio but I found out that it's not changing my task bar on deployed app (Install the app using a MSI file).

So is there a way to do it?

**UPDATE**

To force the icon refresh on my deployed app I have to pin/unpin my icon taskbar, unfortunately this is a user command only so I can't do this in wpf programmatically.
