Does SQLite in case-insensitive?

Does EF Core use SQLite’s NOCASE comparison?

The last code listing uses SQLite’s ADO.NET APIs (the layer beneath EF Core) to replace SQLite’s built-in NOCASE comparison with .NET’s more complete implementation. (using pure unicorn magic ) Yes, my first two comments also apply to EF Core 1.x. Sorry, something went wrong.
