I need to access Windows Azure Service Management REST API directly from the deployed Cloud Service instance. To do that I need to access X509 certificate, right? When I deploy a cloud service, the service management certificate is not deployed to the instance. At least I could not find any certificate in the deployed Virtual Machine (certmgr.msc).
How shall I deploy the X509 certificate to the Cloud Service instance?
Follow the instructions here. These are for SSL certificate with private key, but are 1:1 for a public key only certificate. This way you will have access to the certificate in all your Instances.
