What it's for
This extension enables other Visual Studio extensions (like the EF Core Power Tools) that use the DDEX APIs to do things like the following.
It also enables connecting to SQLite databases in Server Explorer to see their schema and data. This read-only view can be useful when debugging your app.
What it's not for
There are plenty of great tools out there to help you design SQLite databases and queries. This is not one of them. The following features are specifically outside the scope of this project.
If you're looking for a great tool that does all of that inside Visual Studio, I recommend the SQLite Toolbox.
