In our solution, export mpp files has no project calender

Aspose.Tasks Product Family
1

We encountered this issue in our project, please help us investigate it.

  1. Our project has a C# dual-framework architecture.

  2. When using Aspose.Task to export MPP files, we found that the exported content does not include the project calendar.

  3. However, when creating a separate project and running the same code, the exported MPP file does include the project calendar.
    Please help us locate the specific issue with the code provided below.

         var project = new Project();
     project.CalculationMode = CalculationMode.None;
     project.WorkFormat = TimeUnitType.Day;
     project.NewTasksAreManual = false;//新任务模式

     project.StartDate = new DateTime(2022, 5, 27);
     project.MinutesPerDay = 480;

     //设置日历
     var calendar = project.Calendar;
     calendar.WeekDays.Clear();
     calendar.Exceptions.Clear();
     //Calendar.MakeStandardCalendar(calendar);
     calendar.Name = "默认日历";

     var sunday = new WeekDay(DayType.Sunday);
     sunday.DayWorking = false;
     calendar.WeekDays.Add(sunday);

     var monday = new WeekDay(DayType.Monday);
     //WeekDay.SetDefaultWorkingTime(monday);
     monday.WorkingTimes.Add(new WorkingTime(new DateTime(2023, 1, 1, 8, 0, 0), new DateTime(2023, 1, 1, 12, 0, 0)));
     monday.WorkingTimes.Add(new WorkingTime(new DateTime(2023, 1, 1, 13, 0, 0), new DateTime(2023, 1, 1, 17, 0, 0)));
     calendar.WeekDays.Add(monday);

     var tuesday = new WeekDay(DayType.Tuesday);
     //WeekDay.SetDefaultWorkingTime(tuesday);
     tuesday.WorkingTimes.Add(new WorkingTime(new DateTime(2023, 1, 1, 8, 0, 0), new DateTime(2023, 1, 1, 12, 0, 0)));
     tuesday.WorkingTimes.Add(new WorkingTime(new DateTime(2023, 1, 1, 13, 0, 0), new DateTime(2023, 1, 1, 17, 0, 0)));
     calendar.WeekDays.Add(tuesday);

     var wednesday = new WeekDay(DayType.Wednesday);
     //WeekDay.SetDefaultWorkingTime(wednesday);
     wednesday.WorkingTimes.Add(new WorkingTime(new DateTime(2023, 1, 1, 8, 0, 0), new DateTime(2023, 1, 1, 12, 0, 0)));
     wednesday.WorkingTimes.Add(new WorkingTime(new DateTime(2023, 1, 1, 13, 0, 0), new DateTime(2023, 1, 1, 17, 0, 0)));
     calendar.WeekDays.Add(wednesday);

     var thursday = new WeekDay(DayType.Thursday);
     //WeekDay.SetDefaultWorkingTime(thursday);
     thursday.WorkingTimes.Add(new WorkingTime(new DateTime(2023, 1, 1, 8, 0, 0), new DateTime(2023, 1, 1, 12, 0, 0)));
     thursday.WorkingTimes.Add(new WorkingTime(new DateTime(2023, 1, 1, 13, 0, 0), new DateTime(2023, 1, 1, 17, 0, 0)));
     calendar.WeekDays.Add(thursday);

     var friday = new WeekDay(DayType.Friday);
     //WeekDay.SetDefaultWorkingTime(friday);
     friday.WorkingTimes.Add(new WorkingTime(new DateTime(2023, 1, 1, 8, 0, 0), new DateTime(2023, 1, 1, 12, 0, 0)));
     friday.WorkingTimes.Add(new WorkingTime(new DateTime(2023, 1, 1, 13, 0, 0), new DateTime(2023, 1, 1, 17, 0, 0)));
     calendar.WeekDays.Add(friday);

     var saturday = new WeekDay(DayType.Saturday);
     saturday.DayWorking = false;
     calendar.WeekDays.Add(saturday);

     //特殊日历
     //var calendar = project.Calendars.Add("Calendar1");
     var exception = new CalendarException();
     //exception.Name = "New Calendar Exception";
     exception.EnteredByOccurrences = false;
     exception.FromDate = new DateTime(2022, 1, 31, 0, 0, 0);
     exception.ToDate = new DateTime(2022, 2, 6, 23, 59, 59);
     exception.Type = CalendarExceptionType.Daily;
     //exception.Month = Month.December;
     exception.DayWorking = false;
     calendar.Exceptions.Add(exception);

     var exception2 = new CalendarException();
     //exception2.Name = "New Calendar Exception";
     exception2.EnteredByOccurrences = false;
     exception2.FromDate = new DateTime(2021, 12, 31, 0, 0, 0);
     exception2.ToDate = new DateTime(2022, 1, 2, 23, 59, 59);
     exception2.Type = CalendarExceptionType.Daily;
     //exception2.Month = Month.December;
     exception2.DayWorking = false;
     calendar.Exceptions.Add(exception2);
     project.CalculationMode = CalculationMode.Automatic;


     project.Save("C:\\InforCenterData\\Temp\\Test我的测试计划" + DateTime.Now.ToString("MMddHHmmss") + ".mpp");

@Jiangqiming,
which version of Aspose.Tasks do you use?

3

The lastest version 23.4

I see that the resulting project contains the modified project calendar, but Monday-Friday are marked as non-working. You should set property DayWorking for these days:

monday.DayWorking = true;
tuesday.DayWorking = true;
etc.

I will create an improvement in our issue tracking system to make this scenario more user-friendly.

If your have another problem, feel free to describe it.

I understand the specific reason now, and it has nothing to do with the dual framework. It is because I have redundant low-version Aspose.Task.dll in the solution, which causes the project calendars to not be displayed in the exported mpp file, even though I have referenced the latest version of the dll.
