Umbraco.Community.CustomValidator - New Package for v17

Hi all!

I’ve just released my first package for Umbraco which provides a framework for doing custom validation in the backoffice with strongly typed models.

I’d love to hear any feedback people have! and for those in the Yorkshire area join me in person at Umbraco Leeds this Thursday where I’ll be doing a talk on how it works UmbLeeds Lightning Talks: Agentic Development & Backoffice Validation, Thu, Feb 5, 2026, 6:30 PM | Meetup

Congratulations! It looks like a useful package. I just did something custom to do something similar.
