Do I have to use IgnorePropertyType instead of ImplementPropertyType to implement my own logic? about modelsbuilder.original

The tool parses all the files that live in the same directory that already contains the "custom tool" file, ie ContentModelBuilder.cs in your case, if I understand correctly. So this is where you want your partial class to be, too. So Whatever.generated.cs and Whatever.partial.cs end up in the same directory.

And then [ImplementPropertyType("whatever")] on the property in the partial ''should'' be enough.

Either you partial files are not in the right place, and therefore not parsed, or there's a bug somewhere.

Ah, then that was the obvious thing I'm missing ;-)
I had my generated models in Models\Generated, the partial implemented models in \Models

Thanks for your prompt response!
