SetWindowsHookEx is not supported on any WindowsCE (read: Mobile) version. Hooks in general are not supported, in fact.
However, if you're willing to use undocument/unsupported APIs you can pull SetWindowsHookEx out of coredll.dll, and call it as you would on proper Windows. You want WH_KEYBOARD_LL, which a little googling says is 20.
You'll actually need to pull out pointers to the following methods: SetWindowsHookEx, CallNextHookEx, and UnhookWindowsHookEx.
Your code will resemble (this is untested):
//myHook.dll
LRESULT myLowLevelKeyboardProc(int nCode, WPARAM wParam, LPARAM lParam)
{
//You'll need to pull a reference to CallNextHookEx out of coredll as well
if(nCode < 0) return CallNextHookEx(nCode, wParam, lParam);
KBDLLHOOKSTRUCT data = *((PKBDLLHOOKSTRUCT)lParam);
//Do something with data
return CallNextHookEx(nCode, wParam, lParam);
}
//Main Code, which ignores all the nasty function pointers you'd ACTUALLY have to use to do this
...
HHOOK hook = SetWindowsHookEx(WH_KEYBOARD_LL, pMyLowLevelKeyboardProc, hMyHookDll, 0);
...
//Some point in the future
UnhookWindowsHookEx(hook);
I would strongly suggest against this however. I doubt very much that this code will keep working for all future versions of Windows Mobile. Consider some other way to achieve whatever it is you're actually after.
I can't say I have any recommendations for free compilers or IDEs. Anything other than Visual Studio for C/C++ always causes me a lot of frustration. I think this is more a reflection of my habits than a commentary on any other tools.

On the desktop it is possible to install WH_KEYBOARD_LL hooks using pure managed code. You'll have to experiment to see if the same holds true for Windows Mobile. My examples are in C as they're the "most likely" to work; as noted this is an unsupported operation.

i'm doing a tool on windows mobile, it can run in background and capture key which user pressed (in global), so can i do it in c#?

Follow the above URL. It has the required code to work on Windows Mobile and Windows CE and also has a good explanation as well as a forum to discuss further on...
Forgot to say that the code is in C# as required by some other users...
