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:

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.

I think that it is a bug. I tried @musli’s idea, creating a runner.exe that runs the real application. As of now, changing the application icon in the taskbar under the following conditions has worked.

1. if I call the runner.exe directly from the program directory.
2. or if I pin a shortcut to the runner.exe in the start (pin to start).

But now it gets interesting: If I pin the original exe in addition to the pinned runner.exe in the startup, then the change of the application icon in the taskbar does not work anymore.

So, in my opinion, the problem is related to Windows’ own shortcut management.

@563203132 @lindexi Maybe there’s a problem with your packaging, and I created a wix SetupProject that uses it to compile a .msi installation package, and the program that runs out doesn’t have that problem There’s also a small finding that your problem won’t exist when the taskbar doesn’t merge icons (from Quicker of master) Demo.zip
