    7.3.4 > 7.4 RC upgrade guide

    Is there any guides on upgrading from 7.3.x to 7.4rc. It seems there are a number of breaking changes?

    On the 7.4 download page you can see the list of breaking changes:

    I've tried some 7.3 upgrades with NuGet and so far everything still works.

    Hi all!

    After updating to version 7.4RC1 I got the error:

     [MissingMethodException: Method not found: "Boolean Umbraco.ModelsBuilder.Configuration.Config.get_EnableLiveModels()".]
       Umbraco.ModelsBuilder.AspNet.LiveModelsProvider.get_IsEnabled() in X:\Projects\Umbraco\ModelsBuilder\Zbu.ModelsBuilder\Umbraco.ModelsBuilder.AspNet\LiveModelsProvider.cs:45
       Umbraco.ModelsBuilder.AspNet.LiveModelsProviderModule.Install() in X:\Projects\Umbraco\ModelsBuilder\Zbu.ModelsBuilder\Umbraco.ModelsBuilder.AspNet\LiveModelsProvider.cs:156

    Does anyone know how I can resolve this?

    I'm facing the same "Method not found"-error. Any news about it?

    Upgrading 7.3.4. to 7.4 Final After a couple of hours of headscratching i have a couple of heads-ups for those in trouble :)

    · Read the upgrade guide

    · Compare /config/applications.config if you have custom sections like SEOChecker

    · Compare grid.editors.config.js if you have custom grid editors.

    · If youre using LeBlender and have trouble in the backend, Download umbraco.dll from here
