Extensible productivity tool for exposing common classes in application building

Architecture for developing an application. The architecture provides an entry point to commonly used classes of an application development framework. A developer begins a project which predefines a set of collection classes. An exposer component includes an identifier component and a compiler for generating accessors to the collected classes. The identifier uses an attribute on a collection class which a compiler dynamically extracts in order to generate accessors to the desired collected classes and compiles the generated collection classes for use in the namespace.
