ServiceStack.OrmLite - Fast, Simple, Typed ORM for .NET

•    CSharp

Follow @ServiceStack or join the Google+ Community for updates, or StackOverflow or the Customer Forums for support.OrmLite's goal is to provide a convenient, DRY, config-free, RDBMS-agnostic typed wrapper that retains a high affinity with SQL, exposing intuitive APIs that generate predictable SQL and maps cleanly to (DTO-friendly) disconnected POCO's. This approach makes easier to reason-about your data access making it obvious what SQL is getting executed at what time, whilst mitigating unexpected behavior, implicit N+1 queries and leaky data access prevalent in Heavy ORMs.

ServiceStack.Redis - .NET's leading C# Redis Client

•    CSharp
