# Version

> The generational version of the entity.

## Definition

* **Type:** Property
* **Namespace:** [Unity.Entities](/engine/7000.0/script-reference/unity/entities.md)
* **Assembly:** UnityEngine.EntitiesModule

```csharp
public int Version { get; set; }
```

### Remarks

The Version number can, theoretically, overflow and wrap around within the lifetime of an application. For this reason, you cannot assume that an Entity instance with a larger Version is a more recent incarnation of the entity than one with a smaller Version (and the same Index).
