Atlassian.Net SDK get all projects and sprints

I am using Atlassian .net SDK from NuGet gallery. I am able to retrieve all the issues with below code:

    var jira = Jira.CreateRestClient("https://xxxx.atlassian.net", "user name", "pwd");

    var jiraIssues = from i in jira.Issues.Queryable

                 orderby i.Created
                 select i;

    foreach (var issue in jiraIssues)
    {
        System.Console.WriteLine(issue.Key.Value + " -- " + issue.Summary);
    }

But I am not able to get all the Projects, Sprints etc. Can anybody help me on this ?
