[dotNetRDF-Support] ReadWriteSparqlConnector OAuth authentication

[Noble, A. (AS01) <Ash...@ho...>]

Hi All,
I'm trying to use the ReadWriteSparqlConnector to connect to a BlazeGraph store that is authenticated with OAuth (Azure Active Directory). Generally making OAuth calls I add an Authorization header to the request, but with the SparqlRemoteEndpoint the only thing I can set is the NetworkCredential which can't handle OAuth.

Is there any suggested way to be able to add a header to the rest calls that ReadWriteSparqlConnector makes?

Here is a working example of what I'm doing with Basic auth, but I need to update it to talk OAuth:

            var networkCredential = new NetworkCredential(_rdfServerConfig.UserName, _rdfServerConfig.Password);
            var endpointUri = new Uri(string.Format("{0}/bigdata/namespace/{1}/sparql", _rdfServerConfig.RdfServer,_rdfServerConfig.DefaultDb));
            var queryEndpoint = new SparqlRemoteEndpoint(endpointUri) { Credentials = networkCredential };
            var updateEndpoint = new SparqlRemoteUpdateEndpoint(endpointUri) { Credentials = networkCredential };
            VDS.RDF.Options.ForceHttpBasicAuth = true;

            return new ReadWriteSparqlConnector(queryEndpoint, updateEndpoint);

Cheers,
Ash.
