I am just getting to know NORMA (having used Visio Modeler a long time ago) and so far:
A) Installed NORMA in VS 2019 (CE) and completed the Tutorial.
B) Imported a complex model from an SQL server (Express)DB with no errors.
C) Had several failures trying to import Access databases running in Access 2010
All attempts to import an Access file result in an error dialogue with the message:
The specified invariant name is not supported"
Connection Tests are OK. Both mdb and .accdb formats give the same result.
