Error in Client - Three Legged Auth dies when there is no refresh token.

[cdarrigo]

WHen the refresh token is null (which is true when implementing a client using threelegged client mode), the following exception is thrown ArgumentNullException

from here

public string Code { get { return base.Parameters["code"]; } set { if (string.IsNullOrEmpty(value)) { throw new ArgumentNullException("value"); } base.Parameters["code"] = value; } }
