Generate SM2 certificate signing request with Pkcs10CertificationRequest class

[bian8021]

Hello,

I want to implement CSR and private key with SM2 algorithm. I am trying to use following code to generate:

var pkcs10CertificationRequest = new Pkcs10CertificationRequest("SM3WITHSM2", subjectName, sm2KeyPair.Public, null, sm2KeyPair.Private);

But it shows "string SM3WITHSM2 not an OID", what does the error mean? does Pkcs10CertificationRequest support to generate SM2 CSR?
