I have a .sdf
file (265 MB), and I need to open it with Visual Studio 2022. I have downloaded 'SQLite/SQL Server Compact Toolbox'. Then I added connection and chose 'SQL Server Compact 4.0 (by Simple ErikEJ).
When I clicked on 'test', it displayed:
Test connection succeeded
But when I clicked on 'OK', it displayed:
Unable to find the requested .Net Framework Data provider. It may not be installed
I have searched some solutions about it. I tried to modify 'machine.config' file, but it didn't work.
Also I downloaded and installed 'SSCERuntime-ENU.exe', it didn't work,too.
So how to open .sdf
file in Visual Studio?
Updated: I opened 'SQLite/SQL Server Compact Toolbox', then click 'Add SQL server compact connection'. When I tested connection, it displayed the error below.

Actually this is a chemical structure-data file. Although the extension is .sdf, it is different from SQL Server Comapct Database file. Many chemical structure software can open it, like DataWarrior.
