using System.Collections.Specialized;
using Redmine.Net.Api;
using Redmine.Net.Api.Types;

namespace RedmineTest
{
    class Program
    {
        static void Main(string[] args)
        {
           string host = "<host>";
           string apiKey = "<api-key>";

           var manager = new RedmineManager(host, apiKey);

           Issue issue = new Issue();
           issue.Project = IdentifiableName.Create<IdentifiableName>(<project-id>);
           issue.Priority = IdentifiableName.Create<IdentifiableName>(<project-id>);
           issue.Subject = "Example";
           issue.Description = "Description";
           issue.Category = IdentifiableName.Create<IdentifiableName>(<project-id>);
           issue.Status = IdentifiableName.Create<IdentifiableName>(<project-id>);
           issue.AssignedTo = IdentifiableName.Create<IdentifiableName>(<project-id>);
           issue.ParentIssueId = <parent-issue-id>;

           Issue savedIssue = manager.CreateObject(issue);
           Console.WriteLine("Saved issue {0}." ,savedIssue);
       }
    }

After version 4.6.5
