```csharp
public TimeSpan ActivationSchedulingQuantum
```

Gets or sets the soft time limit on the duration of activation macro-turn (a number of micro-turns). If an activation was running its micro-turns longer than this, we will give up the thread. If this is set to zero or a negative number, then the full work queue is drained (MaxWorkItemsPerTurn allowing).
