• LINQ Support
  LightSpeed includes LINQ support when targeting .NET 3.5 or above meaning you can leverage either the built in LINQ-to-LightSpeed querying model or the traditional LightSpeed querying model. This feature effectively enables LINQ to MySQL, LINQ to PostgreSQL, LINQ to SQLite, LINQ to Sql Server and LINQ to Oracle.
• Migrations built in
  Save yourself the pain of writing sql migrations - LightSpeed can manage schema migrations for you! Save hours of with this one feature alone!
• Convention Over Configuration
  LightSpeed does away with verbose XML configuration and mapping files in favor of a simple, consistent set of conventions for how domain objects should be built. This approach increases agility by both minimizing unnecessary duplication, and, by providing a consistent set of patterns for how the domain model is represented.
• Small & Lightning Fast
  LightSpeed is designed to be fast. It employs several advanced performance enhancing techniques such as dynamic methods (LCG) instead of reflection, multi-reader eager loading, lazy loading and optimized query batching. Our internal benchmarks show LightSpeed to be faster than NHibernate.
• Employs Best Practice Patterns
  LightSpeed uses patterns from domain-driven design including Repository, Unit of Work, Entity, Value Object and Specification.
• Designed for Testability
  LightSpeed is designed with testability in mind. It allows for mocking of key interfaces along with built-in support for transactional testing. Additionally, due to LightSpeed's transparent support for multiple databases, unit testing can be performed against a small local database such as SQLite.
• Legendary support
  We answer most help requests in under 24 hours and add new features and enhancements to our nightly builds based on feedback so all users can enjoy them!
