UID editorUID = new UIDClass();
editorUID.Value = "esriEditor.Editor";
_Editor = ArcMap.Application.FindExtensionByCLSID(editorUID) as IEditor;

UID editSnapUid = new UIDClass();
editSnapUid = "esriEditorExt.EditorSnapping";
IEditorSnapping _EditorSnapping= editor.FindExtension(editSnapUid) as IEditorSnapping
}

Public Sub GetEditorSnappingByCLSID()
Dim eUID As UID = New UIDClass()
eUID.Value = "esriEditor.Editor"
'This Code would be used in an Add-in, if the project is not an add-in the Application object can be 'obtained from the hook parameter.
_Editor = TryCast(My.ArcMap.Application.FindExtensionByCLSID(eUID), IEditor)

Dim chipUID As UID = New UIDClass()
chipUID.Value = "esriEditorExt.EditorSnapping"
Dim _SelectionChip As IEditorSnapping = TryCast(_Editor.FindExtension(chipUID), IEditorSnapping)
