Custom CSP buiding -getting started-

I obtained MS Microsoft Cryptographic Service Provider Development Kit.
I read readme.txt and then I got stuck.
There is no support for XP.
Dose it means that I cannot develop custom CSP for XP on XP computer?
(Suggestion to Microsoft is to update the DK, please)

Reading these posts I found here I found out that it's possible to patch
advapi32 on mine own so I did. I then installed the csp.dll as is stated in
CSPDK (part Installation Instructions). When I run the test app from CSPDK I
get a following message:

Calling CryptAcquireContext - CryptAcquireConext returned error 80090019
FAILED

Is this normal behavior of correctly installed sample application or I'm
missing something?

Also I tried to run CSP test suite to try to see what happens if I use it on
sample CSP (csp.dll), but I cannot find sample csp.dll in CSP name list. Any
help or suggestions would be highly appreciated.
