NTLM Authentication using RestSharp?

I am trying to use NTLM authentication for my REST calls to TeamCity using RestSharp.

IRestClient _client=new RestClient(_url);
_client.Authenticator = new NtlmAuthenticator
(System.Net.CredentialCache.DefaultNetworkCredentials);

However it is not working. Please suggest if I am missing something.

This now appears to be working properly and can be done very easily utilizing the NTLMAuthenticator like so:

RestClient client = new RestClient(_baseURL);
client.Authenticator = new NtlmAuthenticator();

Try this:

var client = new RestClient(_baseURL)
{ Authenticator = new RestSharp.Authenticators.NtlmAuthenticator()
};

As of RestSharp v107, The NtlmAuthenticator is deprecated.

This worked for me:

var credentials = new NetworkCredential(username, password, domain);
var options = new RestClientOptions(_settings.ServiceEndPoint)
{ UseDefaultCredentials = false, Credentials=credentials
};
var client = new RestClient(options);

Not supported currently. Refer to the below thread.
