In context-aware system, components are dynamically adapted without requiring system to restart, in response to all possible changes in the execution environment. Existing approaches to make such a system more vigorous and safe, are both brittle and time intense. A approach has been devised for dynamic adaptation, to automate the component integration process at runtime by accessing the equivalent component from a set of diversified components. The .NET technology allows developers to adapt run-time component by specifying assertions on the component’s services and also allows performing comparison of these assertions. These assertions will help us to compute metadata for each component in the repository. This metadata-driven component selection is an efficient and promising mechanism. In this paper, we describe the mechanism for component adaptation using .NET approach, by considering a system in dynamic context having proxy switcher and network switcher components.
