This code crashes using Compact Framework on a mobile device WM 6.0x:

   FRequest = new TElCertificateRequest(null);
   FRequest.Subject.Count = 6;
   for (int i = 0; i <= 5; i++) FRequest.Subject.set_Tags(i, SBASN1Tree.Unit.SB_ASN1_PRINTABLESTRING);
   FRequest.Subject.set_OIDs(0, SBUtils.Unit.SB_CERT_OID_COUNTRY);
   FRequest.Subject.set_Values(0, SBUtils.Unit.BytesOfString("DE"));
   FRequest.Subject.set_OIDs(1, SBUtils.Unit.SB_CERT_OID_STATE_OR_PROVINCE);
   FRequest.Subject.set_Values(1, SBUtils.Unit.BytesOfString("*******"));
   FRequest.Subject.set_OIDs(2, SBUtils.Unit.SB_CERT_OID_LOCALITY);
   FRequest.Subject.set_Values(2, SBUtils.Unit.BytesOfString("*******"));
   FRequest.Subject.set_OIDs(3, SBUtils.Unit.SB_CERT_OID_ORGANIZATION);
   FRequest.Subject.set_Values(3, SBUtils.Unit.BytesOfString("*******"));
   FRequest.Subject.set_OIDs(4, SBUtils.Unit.SB_CERT_OID_ORGANIZATION_UNIT);
   FRequest.Subject.set_Values(4, SBUtils.Unit.BytesOfString("***"));
   FRequest.Subject.set_OIDs(5, SBUtils.Unit.SB_CERT_OID_COMMON_NAME);
   FRequest.Subject.set_Values(5, SBUtils.Unit.BytesOfString("************************"));


A strange thing is, that there is no internal exception thrown, but WM error reporting pops up with error code 0xC0000005.
Mysteriously that code works while connected via Mobile Device Center on the same device, formerly ActiveSync.

using: SecureBlackbox.PKI.dll

Thank you for the report.

1) Did you check on emulator as well? If no, please do. As we are only able to check on emulator, it's important to narrow down the problem a bit.
2) What version of .NET CF are you using? WM 6.0 uses .NET CF 2.0 as far as I remember.

Sincerely yours
Eugene Mayevski

I checked this in an emulator image "Windows Mobile 6 Professional VGA Emulator" and .NET CF 3.5. The code works, but needs a huge amount of time. I guess around 45min (in words: forty-five minutes!) with a host processor load of 45%. Using a real device connected in ActiveSync-Debugmode this takes 'only' 2min.
