dotConnect for SQLite is an enhanced ORM enabled data provider for SQLite that builds on ADO.NET technology to present a complete solution for developing SQLite-based database applications. With support for Entity Framework, NHibernate, and LinqConnect ORMs, it introduces new approaches for designing application architecture, boosts productivity, and leverages database applications.

Fast and Advanced ADO.NET Provider
dotConnect for SQLite offers both high-performance connectivity to the SQLite database and a number of innovative development tools and technologies. It supports a wide range of SQLite-specific features, such as user-defined functions, CEROD and SEE encryption extensions, support for enabling SQLite extensions with connection string parameters, etc.

RAD Approach
dotConnect for SQLite provides a vast number of GUI tools that increase your productivity. It integrates into Visual Studio Server Explorer and other tools and provides advanced visual component editors to simplify component tweaking. DataSet tools, such as DataSet Wizard, DataSet Editor, DataSet Manager, provide you an easy way to create and edit typed and untyped DataSets.

ORM Solutions
The app for SQLite offers enhanced ORM support with a bundled visual designer for ORM models - Entity Developer. dot Connect for SQLite supports ADO.NET Entity Framework, NHibernate, and LinqConnect (formerly known as LINQ to SQLite) - our own ORM solution, closely compatible to Microsoft LINQ to SQL, while extending its functionality with its own features.
