```csharp
public static bool TryGetParentBuild(GUID buildSessionGuid, out GUID parentBuildSessionGuid)

### Returns

| Type                                                          | Description                                                                                       |

| [bool](https://learn.microsoft.com/dotnet/api/system.boolean) | `true` if the build is tracked in the build history and has a recorded parent; otherwise `false`. |

### Remarks

The parent is recorded when the build runs. The value is returned regardless of whether the parent build is actually still present in the build history. For example it could reference a build that has already been deleted by the retention policy.
