4470809 SqlConnection instantiation exception on .NET 4.6 and later after August-September 2018 .NET Framework updates.
|Microsoft is working on a resolution and will provide an update in an upcoming release.|
|After installing this update, third-party applications may have difficulty authenticating hotspots.||This issue is resolved in KB4480967.|
|Applications that use a Microsoft Jet database with the Microsoft Access 97 file format may fail to open if the database has column names greater than 32 characters. The database will fail to open with the error, “Unrecognized Database Format”.|| |
Use one of the following options:
Option 1: Modify the database to ensure that all column names are less than or equal to 32 characters.
Option 2: Convert the database to the .accdb file format. To use the .accdb file format, you must change the Connection string after conversion.
The easiest way to convert is to use Microsoft Access 2010 or earlier.
Option 3: Convert the database to a newer .mdb file format. This doesn’t require a change to the Connection string.
