Bing's move to .NET 7 with Principal Engineer Ben Watson

Summary

The main theme is the intricate, multi-layered architecture of Bing's search engine, specifically focusing on the "federation routing layer." Key subjects include the UX layer, numerous backend repositories and databases, and a classification layer that dynamically selects relevant "plugins." The practical takeaway is that despite its vast number of components, Bing efficiently processes queries by only activating a fraction of them based on classification.
