I have modified MimeMaker_VS2010 sample project to use PKCS11 for S/MIME signing.
Modified part of menuItem_Assemble_Click is below.
When i debug application i see that correct certificate is added to SenderCertStorage (TElMemoryCertStorage), but i get "Sign message error code: 8194" at msg.AssembleMessage.
How can i solve this problem?

PKCS11CertStorage = new SBPKCS11CertStorage.TElPKCS11CertStorage();
PKCS11CertStorage.DLLName = @"C:\Windows\System32\eTPKCS11.dll";
Session = PKCS11CertStorage.OpenSession(0, true);
Session.Login((int)SBPKCS11Base.Unit.utUser, "****");
Cert = PKCS11CertStorage.get_Certificates(0);

SenderCertStorage.Add(Cert, true);
smime.EncoderSignCertStorage = SenderCertStorage;

Thank you for contacting us.

This approach should work. Is it possible that you clean SenderCertStorage or close PKCS#11 session before AssembleMessage is called?

Neither closed, nor cleaned.
At debug, i can see certificate at new "System.Collections.ArrayList.ArrayListDebugView(((SBCustomCertStorage.TElMemoryCertStorage)(((SBSMIMECore.TElMessagePartHandlerSMime)((msg.MainPart).MessagePartHandler)).EncoderSignCertStorage)).CertificateList)).Items[0]" while calling msg.AssembleMessage.
Rest of code is:
TAnsiStringStream sm = new TAnsiStringStream();
int res = msg.AssembleMessage(sm, "utf-8",  SBMIME.TElHeaderEncoding.heBase64, "base64", "base64", false);
