One important feature of pervasive services is their awareness to the surrounding context. The behavior of context-aware pervasive services should be fully defined and deterministic. These services may be implemented using context-aware languages. So far, these languages either have dealt with only one of these features (i.e. fully defined or deterministic behavior) or have not taken into account any of the two features. In this paper, we propose a programming paradigm which facilitates the development of the context-aware pervasive services with fully defined and deterministic behavior. The multifaceted programming entity is the core concept of our proposal. In order to demonstrate the practical validity of the proposed paradigm we extended C# language with multifaceted programming entity.
