I would like to make a new Structure Group when we create a new Folder. In older versions of Tridion we might do this with the TDSE object.

I'm on Tridion Sites 9 and wanted to use something similar and tried with the following code.
StructureGroup newSg = (StructureGroup) session.GetNewObject();

Error CS0311 The type 'Tridion.ContentManager.CommunicationManagement.StructureGroup' cannot be used as type parameter 'T' in the generic type or method 'Session.GetNewObject()'. There is no implicit reference conversion from 'Tridion.ContentManager.CommunicationManagement.StructureGroup' to 'Tridion.ContentManager.SystemWideObject'.

Is my only option here to use the Tridion Core Service?

Use the StructureGroup constructor to get a new SG, something like this:

StructureGroup newSg = new StructureGroup(session, parentSGTcmId);

Here is a snippet from the API docs:

    Thanks Nick! I also found another way to solve it as well :)

        public class NewStructureGroupForImageFolder : TcmExtension
            public NewStructureGroupForImageFolder()

            private void Subscribe()
                EventSystem.Subscribe<Folder, SaveEventArgs>(HandleFolderSave, EventPhases.TransactionCommitted);

            private void HandleFolderSave(Folder folder, SaveEventArgs args, EventPhases phase)
                // create new Structure Group
                Publication pub = folder.ContextRepository as Publication;
                StructureGroup rootSg = pub.RootStructureGroup;
                StructureGroup newSg = rootSg.GetNewObject<StructureGroup>();
                newSg.Title = "a new structure group";
                newSg.Directory = "newsg";
