public static T AddCredential<T>(this T request, ICredential credential) where T : ClientServiceRequest
Add a credential that is used for this request only.
This will override a service-level credential (if there is one).
Do not call more than once per request instance, as each call incrementally adds the provided credential.
To perform identical requests but with distinct credentials, create a separate request instance for each credential.
Parameters
Name
Description
