ScheduleProblemKind

enum.NET 6 / 8 / 10.NET Framework 4.8Binarymission.WinForms.Controls.ProjectManagement

`ConstraintConflict`	A task that `TaskConstraintKind.MustStartOn` a date is held later than that date by its links or its summary. The date it must start on is kept.
`DuplicateLink`	A link repeats an earlier one of the same type between the same two tasks, whatever its lag. The later one is left out.
`DuplicateTask`	Two tasks share an `ProjectTask.Id`. The first in the list is used and the other is left out of the plan.
`InvalidDate`	A date could not be read. `ProjectScheduler` takes dates as `DateTime` values and does not report this kind itself; it is reserved for plans whose dates are read from text.
`LinkCycle`	A link would make tasks wait for each other in a loop. Links are dropped one at a time, latest in the list first, until the loop is broken; each one dropped is reported.
`LinkWithinSummary`	A link joins a summary task to one of its own subtasks, at any depth. The link is left out.
`ParentCycle`	A task's chain of parents leads back to itself. The task is placed at the top level.
`SelfLink`	A link joins a task to itself. The link is left out.
`UnknownParent`	A task names a `ProjectTask.ParentId` that is not in the plan. The task is placed at the top level.
`UnknownTask`	A link names a task that is not in the plan. The link is left out.
`UnsupportedSummaryLink`	A link leads into a summary task by its finish (finish-to-finish or start-to-finish), or out of one by its start (start-to-start or start-to-finish), which a summary's rolled-up dates cannot honour. The link is left out.
