Updated to work with Visual Studio 2012.

The N-Tier Framework for Windows Forms is designed to put the developer in control with tools & APIs for the rapid development of database applications in c#.

NTier is designed to leverage developers' skills and familiarity with Visual Studio and Windows Forms to quickly build large business applications. NTier provides tools, frameworks, designers, extender providers and helpers to make database application development easy without replacing familiar tools completely or simply providing an inflexible code generator.

A key design principal is that each feature of NTier is decoupled from other NTier features and works with and not against the Visual Studio tools, APIs or form designers. The developer is free to use as few or as many features that are found to be useful.

A complete database application generation wizard is provided to help get started quickly.

Supports Microsoft .NET Framework 2.0 and above.
