If there are no models builder items in appSettings, then the entire thing should be disabled by default.

This will allow people to seamlessly upgrade from 7.3 -> 7.4 without any issues that might arise from Models Builder.

Of course for new releases, we will include these config options in the web.config so it is enabled when newly installed

This also means that the 'generate models' button needs to be removed when it is disabled.

Done - setting Umbraco.ModelsBuilder.Enable must be true for anything to happen.

I can confirm models are not generated when this setting is not enabled.

i just upgraded a 7.3.4 to 7.4. After installation the site was really slow. inspecting the Umbraco log i found a warning being fired hundreds of times pr. second. "Umbraco.ModelsBuilder.Umbraco.PureLiveModelFactory - No models". Disabling the models builder in web.config fixed it. So its not disabled by default...

MB is enabled by default - it is the primary way that views will be used in the future with strongly typed models. It is however not enabled by default for upgrades, you need to opt-in to enable it by adding the appSettings keys.

If you have steps to reproduce your issue please open an new ticket with this information. Thanks!
