Hello, I am writing a package for Umbraco 11. I am using ModelBuilder models in my logic in some c# classes/services. I would like to use them but I have so much difficulties to make it work when I deploy my package to Nuget and try to rely on the new generated models.. Like I have included an Umbraco package with document types and content and it is installed via package migration, so my models can be generated again after this package migration runs. But if I don't include my models builder assembly package in nuget I get an error during boot time that the assembly is missing. If I include it later on after the new models builder classes are generated I get errors because there are multiple models for one thing. I digged into Umbraco and got understanding about how Umbraco works with ModelBuilder models with the default factory, crawling the assemblies and loading the types etc etc. and I can't really think about a way on how to make it work. Maybe if I include the models as content which will be restored during the install of the package and then add note to manually move/remove them to the modelsbuilder folder? Do you have some ideas or it is causa perduta.

Hi. My clean starter kit has templates which rely on MoB models being there. The key is to not change the namespace of the models. Use the Umbraco.Cms.Web.PublishedContentModels or whatever it is. Also you need to make sure the doc types are created. Clean starter kit installs the doc types for you. I made a tutorial about how to do such things in this playlist. https://youtube.com/playlist?list=PL90L_HquhD-_g78W-IUX40G7KqFKTXD1V

Hey, Paul. Thanks. I checked your package but the issue on my side is that I have cs files which depend and it is a bit different in that case. Thanks for the nice series. I learnt a lot 🙂

Create interfaces in your package. Make it a requirement to apply those interfaces to the generated models using partial classes.

I actually did something else. In umbraco 11.4.0 it is possible to hook into the models generation and there I check if the model type is from my assembly and I skip generating it

I think there's an elegant way to do that with attributes but don't have the docs at hand.
