I am following the article Using SQLite Embedded Database with Entity Framework and Linq-to-SQL, and have tried installing the SQLite provider, first using the System.Data.SQLite NuGet package, and then by installing the provider via the Setups for 32-bit Windows (.NET /Framework 4.0) installer package (for v1.0.79). After both installs, and a system restart, I still see no SQLite Database File provider in the Add Connection dialogue from Server Explorer.
I can proceed by manually creating a connection string and using external tools to create my SQLite database file, but I still would like to know what is wrong why I do not have the advertised design time support for SQLite despite having installed the latest provider. What could be wrong here?
Ensure the data tools for visual studio were installed correctly as per:

There are various fixes listed, making sure there weren't older tools installed first, etc. I'm going to give it a try, but the article may help you out.
