Konstruktor is a tiny dependency injection container for .NET 3.5.

it features:

• Constructor Injection
• Open Generic interfaces and generators.
• Automatic factory generation and injection via Func<> and Func<,>
• Lifetime management through IDisposable
• Constructor argument injection.
• Hierarchical lifetime scoping
• Thread-safe

Intentionally, it does not support:

• field / property injection (though it can be done by specifying generator methods).
• XML configuration
