We demonstrate that Microsoft LINQ can be used as a convenient tool to define architectural assertions. We introduce an abstract model of software based on a directed multigraph and formalize the notion of software architecture and architectural assertions. We demonstrate how Microsoft Visual Studio can be harnessed to extract the architecture of a given software project and append it with assertions using LINQ notation. In particular we explain the flow of data processing that takes place within Visual Studio engine. We follow with examples of assertions selected to demonstrate the expressive power of our approach. We conclude by showing subsequent areas of research worth following in order to deepen the research indicated in this paper. Position
