# uip rpa-legacy type-definition

> `uip rpa-legacy type-definition` inspects any .NET type from a project's dependencies — enum values, properties, methods, constructors, and base types. Useful when an activity returned by [`find-activities`](./uip-rpa-legacy-find-activities.md) takes an argument whose type you need to construct or interpret.
