If you try to reference a property that doesn't exist in litdb you first get an intelli-sense error at dev time / compile error at build time and a runtime validation error at runtime that prevents the query from being executed.

The idea is that your App models represents your database's schema which your App's logic is bound to. You can also use litdb schema APIs [1] to create your database tables so that they're in sync.
