Remarks
This method is for internal use. It can access certain Object Spaces XAF uses internally (for example, the Object Space used by the Security System). Do not use such Object Spaces in your applications because this may cause unexpected behavior. Instead of this, implement the approaches below.
To access an object’s Object Space in the class code, use one of the following options:
- Implement the IObjectSpaceLink interface in non-persistent classes.
- Use the automatically implemented IObjectSpaceLink interface in EF Core classes.
- Use the object’s Session in XPO persistent classes.
In other cases, create a new Object Space and use the GetObject(Object) method to retrieve an object in the current Object Space.
