sqlceoledb40.dll

Microsoft SQL Server Compact provider for Windows.

The interesting thing about this DLL is that there is the ProgId Microsoft.WINDOWS.SQLLITE.OLEDB.4.0 with the CLSID {3BE786A0-0366-4F5C-9434-25CF162E475E} which points to the InProcServer32 sqlceoledb40.

So, the question is if this DLL is also(?) used for an SQLite data source.
