Someone made this suggestion:

I think you either need to call ReleaseDispatch() between invocations of
QueryAllRecords() or create a "new" Recordset each time and delete when you're done.

I don't grok this. ReleaseDispatch() is on what object? I don't see it anywhere.

What do you mean by "new" and "delete" Recordset? QueryAllRecords() returns a Recordset. I assume that C# manages this object like others. I don't need to explicitly delete it.

I'm missing something obvious or fundamental.
