Is Attestation Verifiable Credentials Type repo demo available in c#?

[sergiosolorzano]

I have tested successfully idtokenhint demo and I am trying unsucessfully attestation verifiable credentials type , similar to the Woodgrave Employee Onboarding Demo, is this code available in c#?

I can request the issuance of the VC but Authenticator doesn't request the user to Present a verifiable credential in order to issue one, thus the issuance of the VC doesn't get authorized.

Meaning in my case I need the Authenticator to request the VerifiedCredentialExpert VC first but I don't see how to trigger this on Authenticator, I tried this on issuance_request_config.json file, I also tried adding requestedCredentials to type VerifiedCredentialExpert as you see below to suggest to Authenticator to get this first, but didn't change the error behaviour:

     "callback": {
       //In this sample code we will overwrite the callback and use the HOSTNAME dynamicall
       //make sure you use ngrok or something like that when running on a local devbox. 
       //The MS AAD VC Request service needs to be able to reach the callback URI
       "url": "https://YOURPUBLICREACHABLEHOSTNAME/api/issuer/issuanceCallback",
       "state": "STATEWILLBESETINCODE",
       "headers": {
         "api-key": "OPTIONAL API-KEY for ISSUANCE CALLBACK API"
       }
     },
     //The Authority is the DID from your MS AAD Verifiable Credential service, you can copy this from the VC page in azure portal
     "authority": "did:ion: THIS IS YOUR DID FROM THE VC PAGE IN AZURE PORTAL WHICH IS SET IN THE SAMPLE BY COPYING THE VALUE FROM APPSETTINGS.JSON   ",
     "registration": {
       "clientName": "Verifiable Test Register Verifiable Credential"
     },
     //The type needs to be the same as defined in the rules json definitione. The manifest can be copied after the credential has been
     //created in the azure portal
     "type": "VerifiedTestRegistration",
     "manifest": "CREDENTIAL URL IN THIS SAMPLE WILL BE COPIED FROM APPSETTINGS.JSON",
     //Recommendation is to protect issuance payload with a PIN code. 
     //The pincode is set to a random value in code and will be displayed in the UI to the user
     "pin": {
       "value": "123456",
       "length": 4
     },
     //This is an example payload which will be used in the rules file of the credential.
     //The rules files maps information from the ID Token (hint) to the VC
     "claims": {
       "country_of_registry": "",
       "registration_number": "",
     },
     //You can request multiple verifiable credentials at once that's whty the requestCredentials is an array
     "requestedCredentials": [
       {
         "type": "VerifiedCredentialExpert",
         "purpose": "Required presentation of verifiable credentials expert to get Test Registration card.",
         //You can trust multiple issuers who might be issuing the same credential type (for example certifications or diplomas)
         //You need to specify at least 1 trusted issuer DID, for this sample code we copy the IssuerAuthority from appsettings to the request
         //"acceptedIssuers": [ "did:ion: copied from your VC portal in this sample the code copies it from APPSETTINGS.JSON" ]
         "acceptedIssuers": [ "theaccepetedidissuer" ]
       }
      
     ]
   }
