Public Shared Property OidInitializationMode As OidInitializationMode

Property Value

Type	Description
OidInitializationMode	An OidInitializationMode enumeration value specifying when a new GUID value is assigned to the Oid property.

Available values:

Name	Description
AfterConstruction	Specifies that a new GUID value is assigned to the BaseObject.Oid property in the AfterConstruction method override.
OnSaving	Specifies that a new GUID value is assigned to the BaseObject.Oid property in the OnSaving method override.

Remarks

In OidInitializationMode.AfterConstruction mode, the unique object identifier is immediately assigned to a newly created object. In OidInitializationMode.OnSaving mode, the unique identifier is assigned to a newly created object when the object is saved.

The Solution Wizard generates new projects with the FrameworkSettings.DefaultSettingsCompatibilityMode property set to Latest. This sets the OidInitializationMode property value to AfterConstruction using the following code line added to the ModuleBase constructor in the Module.cs (Module.vb) file:

C#

BaseObject.OidInitializationMode = OidInitializationMode.AfterConstruction;

VB.NET

BaseObject.OidInitializationMode = OidInitializationMode.AfterConstruction
