Integration with Project Server 2016 via C#

Question

I try to do a simple task: with help of Visual Studio I try to get info about tasks such as baseline. I can read and get all projects, but can't get list of tasks. How I can get it? Here the example of my code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.ProjectServer.Client;


namespace ProjectAPI
{
    class Program1
    {
        private const string pwaPath = "https://XXXXXXXXX"; 
        private static string projName = string.Empty;

        private static ProjectContext projContext;
        private static PublishedTask projTasks;

        static void Main(string[] args)
        {
            projContext = new ProjectContext(pwaPath);
            projContext.Load(projContext.Projects);
            projContext.ExecuteQuery();

            List<string> TasksID = new List<string>();

            foreach (PublishedProject pubProj in projContext.Projects)
            {
                Console.WriteLine("\n\t{0} : {1}", pubProj.Name, pubProj.CreatedDate.ToString());
                foreach (PublishedTask item in pubProj.Tasks)
                {
                    TasksID.Add(projTasks.Name);
                                    }
                Console.WriteLine("\nProject ID : Project name : Created date");
            }

            Console.Write("\nPress any key to exit: ");
            Console.ReadKey(false);

        }
    }
}

After that i have following error:

"Microsoft.SharePoint.Client.CollectionNotInitializedException" in Microsoft.SharePoint.Client.Runtime.dll

The collection has not been initialized. It has not been requested or the request has not been executed. It may need to be explicitly requested.

You need to load the tasks first:

foreach (PublishedProject pubProj in projContext.Projects)
{
   Console.WriteLine("\n\t{0} : {1}", pubProj.Name, pubProj.CreatedDate.ToString());
   projContext.Load(pubProj.Tasks);
   projContext.ExecuteQuery();
   foreach (PublishedTask item in pubProj.Tasks)
   {
      foreach (PublishedTask pubTask in pubProj.Tasks)
      {
         Console.WriteLine("\n{0}", pubTask.Name);
      }
   }
}
