TaskLink

class.NET 6 / 8 / 10.NET Framework 4.8Binarymission.WPF.Controls.ProjectManagement

A dependency between two tasks: the successor waits for the predecessor.

public class TaskLink : INotifyPropertyChanged

Inherits from / implements: INotifyPropertyChanged

Remarks

A link into a summary task holds back every subtask in it, and a link out of one waits for all of them. Because a summary's dates belong to its subtasks, only FinishToStart and StartToStart can lead into a summary, and only FinishToStart and FinishToFinish can lead out of one; any other is reported as a problem and left out.
