This white paper discusses how an IDE can be transformed from a generic IDE to an application-specific IDE, allowing it to play a central role in capturing the knowledge a developer has or gains over the course of creating the application, associating that knowledge in a meaningful with the application, and then using the knowledge to enable others to easily navigate and modify that application without having to go through the same learning process all over again. Explore how a technology, known as Application Factories, enables an IDE to manifest application-specific metadata with interactive, just-in-time tooling. Learn how developers can customize applications more efficiently, greatly reducing the cost and overhead associated with the complexity of today's applications.
