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 ?
