Currently the only solution that we sell for .NET data access is the DBISAM ODBC driver, which can be used from .NET using the ODBC.NET data provider. This allows for both local and multi-user (file sharing) usage, as well as client-server usage. There is a native 3rd party ADO.NET data provider available for client-server usage only from Retail Decision. This provider is not supported by Elevate Software, however.
