Building a Robust Deep Link Router in .NET MAUI
Deep linking looks trivial until real apps arrive: cold-start timing, unauthenticated users, malformed parameters, duplicate delivery, and Android vs iOS delivering the same link through different mechanisms. Jorge Perales Diaz reframes it as a routing problem and builds a reusable Deep Link Router for .NET MAUI that keeps public URLs independent from your internal Shell hierarchy.
What you’ll learn
- External vs internal routes — why a public URL like
/products/42shouldn’t map directly to a Shell route, and how a router becomes the stable translation layer - Parse, match, validate — a
DeepLinkRequest, an allowlisted route registry, and a segment matcher that extracts dynamic parameters like/products/{id} - Authentication-aware routing — deferring protected links to login and resuming the original intent afterward with a pending-link store
- Startup, deduplication, and gates — waiting on real application readiness, a
SemaphoreSlimnavigation gate, and duplicate-delivery protection - Platform integration and security — thin Android/iOS receivers feeding one cross-platform router, route priorities, input validation, and redacting sensitive query values from logs
