Mismatches between pre-qualified existing components and the particular reuse context in applications have been a major factor hindering component reusability. Although component adaptation has acted as a key solution of eliminating these mismatches, it often appears impossible for adaptation at a deep level with tolerable code overheads and human work. In this paper, we address the above problem by realizing the Scenario based Generative component Adaptation (SAGA) approach in the .NET framework. The developed prototype tool (SAGA Bench) helps to achieve deep adaptation with little code overhead through three key techniques: XML-based component specification, interrelated adaptation scenarios, and corresponding component adaptation and generation. The whole process aims to be highly automatic, with necessary user interaction only at XML document level.
