Vista - It takes 10-20 secs to start first WPF app after system boot

Hi,
I have a concern about a startup time of WPF applications.
In my system - Pentium-M 1.8G, ATI FireGL2-128MB and 1GB System Memory, this
spec is enough I believe because the WinSAT rate is '2' -, It takes 10-20
seconds to start WPF application. This is common issue for Vista 5365 and
WinXP with WinFX Runtime.
But, Once the 'first' WPF app has started, WPF apps which starts after that
can start immediately.

Are there any workaround or fix plan about this issue?
If not, it's hard to use WPF for applications that require less latency for
startup - like as application launcher or onscreen sound volume control app.

Hi Mamoru,

I would not blame it on WPF itself. It is a known effect of starting
a .NET app for the first time after reboot.
The initializing process of the CLR and some additional init of the WPF
runtime need time!
