c# - SSL Certificate: A specified logon session does not exist -

i have created method create certificate, store certificate store , bind port. here method:

private static void createstoreandbindcertificate(string a_ipaddress, string a_ipport)         {             guid _appid = guid.parse("b30f5be6-2920-4fa1-b0a6-5a56b63051bc");              var _rootcert = new rootcertificatecontainer("cn=myapp root ca", 1024);             var _servercert = new servercertificatecontainer("cn=myappapi", _rootcert, 1024);              //here certificate created , store             string _pathrootcertcer = path.combine(path.gettemppath(), "root-cert.cer");             string _pathservercerpfx = path.combine(path.gettemppath(), "server-cert.pfx");              _rootcert.x509certificate.privatekey = null;             file.writeallbytes(                 _pathrootcertcer,                 _rootcert.x509certificate.export(x509contenttype.cert)             );              var _servercertpfx = new pfx(_servercert.x509certificate);             file.writeallbytes(_pathservercerpfx, _servercertpfx.generatepfxfile());              process.start(                 new processstartinfo()                 {                     createnowindow = true,                     windowstyle = processwindowstyle.hidden,                     filename = "certutil",                     arguments = string.format("-f -p -importpfx \"{0}\"", _pathservercerpfx)                 }             ).waitforexit();              try             {                 icertificatebindingconfiguration config = new certificatebindingconfiguration();                 var _ipport = new ipendpoint(ipaddress.parse(a_ipaddress), convert.toint32(a_ipport));                 var certificatethumbprint = _servercert.x509certificate.thumbprint.tolower();                 if (config.query(_ipport).length > 0)                     config.delete(_ipport);                 config.bind(new certificatebinding(certificatethumbprint, storename.my, _ipport, _appid));             }             catch (exception ex)             {                 throw new exception(ex.message);             }         } 

when execute method parameters: createstoreandbindcertificate("127.0.0.1", "9001"), error: a specified logon session not exist. may have been termintaed.
missing?

for certificate bind in port want need create .pfx certificate using password. make same small changes:

const string passwordpfx = "mypassword"; 

should added in beginning of method. change:

var _servercertpfx = new pfx(_servercert.x509certificate); 

to

var _servercertpfx = new pfx(_servercert.x509certificate, passwordpfx); 

change:

process.start(                 new processstartinfo()                 {                     createnowindow = true,                     windowstyle = processwindowstyle.hidden,                     filename = "certutil",                     arguments = string.format("-f -p  -importpfx \"{0}\"", _pathservercerpfx)                 }             ).waitforexit(); 

to:

process.start(                 new processstartinfo()                 {                     createnowindow = true,                     windowstyle = processwindowstyle.hidden,                     filename = "certutil",                     arguments = string.format("-f -p {0} -importpfx \"{1}\"", passwordpfx, _pathservercerpfx)                 }             ).waitforexit(); 

another possible solution not use password @ have remove -p processstartinfo arguments. below:

process.start(                 new processstartinfo()                 {                     createnowindow = true,                     windowstyle = processwindowstyle.hidden,                     filename = "certutil",                     arguments = string.format("-f -importpfx \"{0}\"",  _pathservercerpfx)                 }             ).waitforexit();
