sqlite-net is a lightweight .NET ORM library for SQLite, providing both synchronous and asynchronous APIs. It maps C# classes to database tables via attributes, supports CRUD operations, LINQ-like queries, transactions, migrations, encryption (SQLCipher), and backup. The library is implemented in two main source files (SQLite.cs and SQLiteAsync.cs) and uses SQLitePCLRaw or P/Invoke to interface with native SQLite. It targets .NET Standard 2.0, .NET 8, and .NET 9, and is designed for cross-platform use including Xamarin, UWP, and desktop applications. The codebase is well-structured with performance optimizations like fast column setters and prepared statement caching, and includes a comprehensive test suite. It is actively maintained with recent commits and CI integration.
