Vista - Problem with CryptRegisterOIDInfo in Microsoft "Longhorn" Server Beta2

When I call CryptRegisterOIDInfo with pInfo parameter pointing on
"old-style" CRYPT_OID_INFO structure (cbSize = 28) without pwszCNGAlgid and
pwszCNGExtraAlgid members, I get error about invalid parameter.
If use CRYPT_OID_INFO with new members (csSize = 36) it's OK.

Usually, there are back-compatibility in CryptoAPI for such changes...

The repro-example is:

typedef struct _CRYPT_OID_INFO_LH
{
DWORD cbSize;
LPCSTR pszOID;
LPCWSTR pwszName;
DWORD dwGroupId;
union {
DWORD dwValue;
ALG_ID Algid;
DWORD dwLength;
};
CRYPT_DATA_BLOB ExtraInfo;
LPCWSTR pwszCNGAlgid;
LPCWSTR pwszCNGExtraAlgid;
} CRYPT_OID_INFO_LH, *PCRYPT_OID_INFO_LH;

CRYPT_OID_INFO OIDInfo =
{
sizeof(CRYPT_OID_INFO),
"1.2.3",
L"Test",
CRYPT_ENHKEY_USAGE_OID_GROUP_ID
};
CRYPT_OID_INFO_LH OIDInfoLH =
{
sizeof(CRYPT_OID_INFO_LH),
"1.2.3",
L"Test",
CRYPT_ENHKEY_USAGE_OID_GROUP_ID
};
OIDInfoLH.pwszCNGAlgid = L"";
OIDInfoLH.pwszCNGExtraAlgid = L"";

DWORD dwError;
BOOL res;
res = CryptRegisterOIDInfo(&OIDInfo, 0); // res: FALSE
dwError = GetLastError(); //dwError :0x80070057
res = CryptRegisterOIDInfo((PCCRYPT_OID_INFO)&OIDInfoLH, 0); //res: TRUE
