Hi Sankar,
I have observed following issues in your code:
- Child count is manually set which is not recommended.
- BaseLineStart and BaseLine Finish dates are wrong.
- PercentageComeplete is set manually whereas setting ActualStart and ActualFinish set this valaue automatically.
- Task Start, Finish and Duration are set manually however it is recommended that only start and duration be set, while Finish date be calculated by the library itself.
- Summary task start, finish duration etc. is set manually however it should also be calculated by the library.
- While setting the Predecessor of a task, name of the predecessor task is set instead of ID.
Here is a sample code which can be used as guide line to accomplish the task.

WorkingTime wt2 = new WorkingTime();
wt2.FromTime = new DateTime(1, 1, 1, 13, 0, 0, 0);
wt2.ToTime = new DateTime(1, 1, 1, 17, 0, 0, 0);
prj.Calendars[0].Days[6].DayWorking = true;
