some troubles with WPF and Windows XP

is .net framework 3 compatible with xp? i install visual studio 9.0 (.net 3.5) on win XP. when i compile a WPF project and try to run it, this error occurs:

cannot initialize application ...... at address 0x<some digits>

(antivirus protection is off)

after first fail of wpf, all other project types (windows applicati开发者_如何学Pythonon, console &...) after compiling don't run. where is problem?

WPF and .NET 3.5sp1 are supported on XP. You can create WPF applications with run on Windows XP.

It sounds like you have some other issue on your XP system. If other project types (ie: console) are failing, this is most likely some other, more serious issue.

Edit:

The System Requirements for .NET 3.5sp1, including WPF, are listed here. Basically, you need to have XPsp2 or better if you're using 32bit Windows XP, but both 32bit and 64bit XP are supported fully.
