Authentication is supported via the CloudFoundry.UAA namespace. Below is some sample code showing how to obtain a bearer token from UAA.
private static AuthenticationContext refreshToken = null;
client = new CloudFoundryClient(new Uri("https://[URL TO PCF INSTANCE]"), new System.Threading.CancellationToken());
CloudCredentials credentials = new CloudCredentials();
credentials.User = "[USER NAME]";
credentials.Password = "[PASSWORD]";
try
{
refreshToken = await client.Login(credentials);
retVal = true;
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
