How to pass WindowState from desktop shortcut into WPF app?

How can I control the initial WindowState (Normal, Minimized, Maximized) of a WPF main window from a desktop shortcut?

The "Run:" combobox of the shortcut's properties dialog let's me choose between "Normal window", "Minimized" and "Maximized". But this option seems to be completely ignored by WPF apps. With WinFor开发者_Go百科ms this was automatically supported with no additional code.

Is there a way to access this option from the launched WPF process? I know I can specify the ProcessStartInfo.WindowStyle property when launching new processes. But how can I access this option from the process being launched?

System.Diagnostics.Process.GetCurrentProcess().StartInfo.WindowStyle

Use NativeMethods.StartupInfo.GetInitialWindowStyle() to get just the initial window state or NativeMethods.StartupInfo.FromCurrentProcess to access the entire information.
