Namespace: [VM.Managed.DAFUL.Constraints](VM.Managed.DAFUL.Constraints.md)  
Assembly: VMDCB.dll

This class is to represent the user subroutine as driver.

```csharp
public sealed class DriverUserSubroutine : Driver, IObservableObject, IDisposableObject, ILinkable, IObject, ILinkContainer, IOwned, IHasID, IEventProvider, ILinkContainerEvent, IVerifiable, IEnableForSimulationScenario

```
