Hello, some advices or guides to create a custom section in umbraco v15? cause i read the documentation about sections/entry points and package manifest but i'm a little bit confused 🙄 any real life sample to follow? And, any particular reason on why i should be using Lit instead of Blazor to create back office components?

This is a bit older but still a good resource to dive in to, it implements a simple implementation for most extension points. https://github.com/KevinJump/TimeDashboard A section is here: https://github.com/KevinJump/TimeDashboard/tree/master/TimeDashboard.Client/assets/src/section We don't support Blazor at this time as our focus is on extending the backoffice through browser standards (in this case: web components).

now i will take a look, my idea would be to create an exportable web component in blazor, if the BO supports generally web components this should work, i'll try to do it as POC, in the meantime thank you!

You'd make a lot of people happy if you could make Blazor work, there's a long thread here https://discord.com/channels/869656431308189746/1220732155412480053 but no real success yet.
